    11\chapter{Macro-Benchmarks}\label{macrobench}
    2 The previous chapter demonstrated the \CFA scheduler achieves its equivalent performance goal in small and controlled \at-scheduling scenarios.
    3 The next step is to demonstrate performance stays true in more realistic and complete scenarios.
    4 Therefore, this chapter exercises both \at and I/O scheduling using two flavours of webservers that demonstrate \CFA performs competitively with production environments.
    5 
    6 Webservers are chosen because they offer fairly simple applications that perform complex I/O, both network and disk, and are useful as standalone products.
    7 Furthermore, webservers are generally amenable to parallelization since their workloads are mostly homogeneous.
    8 Therefore, webservers offer a stringent performance benchmark for \CFA.
    9 Indeed, existing webservers have close to optimal performance, while the homogeneity of the workload means fairness may not be a problem.
    10 As such, these experiments should highlight any \CFA fairness cost (overhead) in realistic scenarios.

     3The next step is then to demonstrate that this stays true in more realistic and complete scenarios.
     4This chapter presents two flavours of webservers that demonstrate that \CFA performs competitively with production environments.

     6Webservers where chosen because they offer fairly simple applications that are still useful as standalone products.
     7Furthermore, webservers are generally amenable to parallelisation since their workloads are mostly homogenous.
     8They therefore offer a stringent performance benchmark for \CFA.
     9Indeed existing solutions are likely to have close to optimal performance while the homogeneity of the workloads mean the additional fairness is not needed.

    1211\section{Memcached}
    13 Memcached~\cite{memcached} is an in-memory key-value store used in many production environments, \eg \cite{atikoglu2012workload}.
    14 In fact, the Memcached server is so popular there exists a full-featured front-end for performance testing, called @mutilate@~\cite{GITHUB:mutilate}.
    15 Experimenting on Memcached allows for a simple test of the \CFA runtime as a whole, exercising the scheduler, the idle-sleep mechanism, as well the \io subsystem for sockets.
    16 Note, this experiment does not exercise the \io subsystem with regards to disk operations because Memcached is an in-memory server.
     12Memcached~\cite{memcached} is an in memory key-value store that is used in many production environments, \eg \cite{atikoglu2012workload}.
     13This also server also has the notable added benefit that there exists a full-featured front-end for performance testing called @mutilate@~\cite{GITHUB:mutilate}.
     14Experimenting on memcached allows for a simple test of the \CFA runtime as a whole, it will exercise the scheduler, the idle-sleep mechanism, as well the \io subsystem for sockets.
     15This experiment does not exercise the \io subsytem with regards to disk operations.
    1716
    1817\subsection{Benchmark Environment}
    19 The Memcached experiments are run on a cluster of homogeneous Supermicro SYS-6017R-TDF compute nodes with the following characteristics.
     18These experiments are run on a cluster of homogenous Supermicro SYS-6017R-TDF compute nodes with the following characteristics:
     19The server runs Ubuntu 20.04.3 LTS on top of Linux Kernel 5.11.0-34.
     20Each node has 2 Intel(R) Xeon(R) CPU E5-2620 v2 running at 2.10GHz.
     21These CPUs have 6 cores per CPUs and 2 \glspl{hthrd} per core, for a total of 24 \glspl{hthrd}.
     22The cpus each have 384 KB, 3 MB and 30 MB of L1, L2 and L3 caches respectively.
     23Each node is connected to the network through a Mellanox 10 Gigabit Ethernet port.
     24The network route uses 1 Mellanox SX1012 10/40 Gigabit Ethernet cluster switch.
     25
     26\subsection{Memcached with threads per connection}
     27Comparing against memcached using a user-level runtime only really make sense if the server actually uses this threading model.
     28Indeed, evaluating a user-level runtime with 1 \at per \proc is not meaningful since it does not exercise the runtime, it simply adds some overhead to the underlying OS scheduler.
     29
     30One approach is to use a webserver that uses a thread-per-connection model, where each incoming connection is served by a single \at in a strict 1-to-1 pairing.
     31This models adds flexibility to the implementation, as the serving logic can now block on user-level primitives without affecting other connections.
     32
     33Memcached is not built according to a thread-per-connection model, but there exists a port of it that is, which was built for libfibre in \cite{DBLP:journals/pomacs/KarstenB20}.
     34Therefore this version can both be compared to the original version and to a port to the \CFA runtime.
     35
     36As such, this memcached experiment compares 3 different varitions of memcached:
    2037\begin{itemize}
    21 \item
    22 The server runs Ubuntu 20.04.3 LTS on top of Linux Kernel 5.11.0-34.
    23 \item
    24 Each node has 2 Intel(R) Xeon(R) CPU E5-2620 v2 running at 2.10GHz.
    25 \item
    26 These CPUs have 6 cores per CPUs and 2 \glspl{hthrd} per core, for a total of 24 \glspl{hthrd}.
    27 \item
    28 The CPUs each have 384 KB, 3 MB and 30 MB of L1, L2 and L3 caches respectively.
    29 \item
    30 Each node is connected to the network through a Mellanox 10 Gigabit Ethernet port.
    31 \item
    32 Network routing is performed by a Mellanox SX1012 10/40 Gigabit Ethernet switch.
    33 \end{itemize}
    34 
    35 \subsection{Memcached threading}
    36 Memcached can be built to use multiple threads in addition to its @libevent@ subsystem to handle requests.
    37 When enabled, the threading implementation operates as follows~\cite{https://docs.oracle.com/cd/E17952_01/mysql-5.6-en/ha-memcached-using-threads.html}:
    38 \begin{itemize}
    39 \item
    40 Threading is handled by wrapping functions within the code to provide basic protection from updating the same global structures at the same time.
    41 \item
    42 Each thread uses its own instance of the @libevent@ to help improve performance.
    43 \item
    44 TCP/IP connections are handled with a single thread listening on the TCP/IP socket.
    45 Each connection is then distributed to one of the active threads on a simple round-robin basis.
    46 Each connection then operates solely within this thread while the connection remains open.
    47 \item
    48 For UDP connections, all the threads listen to a single UDP socket for incoming requests.
    49 Threads that are not currently dealing with another request ignore the incoming packet.
    50 One of the remaining, nonbusy, threads reads the request and sends the response.
    51 This implementation can lead to increased CPU load as threads wake from sleep to potentially process the request.
    52 \end{itemize}
    53 Here, Memcached is based on an event-based webserver architecture~\cite{Pai99Flash}, using \gls{kthrd}ing to run multiple (largely) independent event engines, and if needed, spinning up additional kernel threads to handle blocking I/O.
    54 Alternative webserver architecture are:
    55 \begin{itemize}
    56 \item
    57 pipeline~\cite{Welsh01}, where the event engine is subdivided into multiple stages and the stages are connected with asynchronous buffers, where the final stage has multiple threads to handle blocking I/O.
    58 \item
    59 thread-per-connection~\cite{apache,Behren03}, where each incoming connection is served by a single \at in a strict 1-to-1 pairing, using the thread stack to hold the event state and folding the event engine implicitly into the threading runtime with its nonblocking I/O mechanism.
    60 \end{itemize}
    61 Both pipelining and thread-per-connection add flexibility to the implementation, as the serving logic can now block without halting the event engine~\cite{Harji12}.
    62 
    63 However, \gls{kthrd}ing in Memcached is not amenable to this work, which is based on \gls{uthrding}.
    64 While it is feasible to layer one user thread per kernel thread, it is not meaningful as it fails to exercise the user runtime;
    65 it simply adds extra scheduling overhead over the kernel threading.
    66 Hence, there is no direct way to compare Memcached using a kernel-level runtime with a user-level runtime.
    67 
    68 Fortunately, there exists a recent port of Memcached to \gls{uthrding} based on the libfibre~\cite{DBLP:journals/pomacs/KarstenB20} \gls{uthrding} library.
    69 This port did all of the heavy-lifting, making it straightforward to replace the libfibre user-threading with the \gls{uthrding} in \CFA.
    70 It is now possible to compare the original kernel-threading Memcached with both user-threading runtimes in libfibre and \CFA.
    71 
    72 As such, this Memcached experiment compares 3 different variations of Memcached:
    73 \begin{itemize}
    74  \item \emph{vanilla}: the official release of Memcached, version~1.6.9.
    75  \item \emph{fibre}: a modification of vanilla using the thread-per-connection model on top of the libfibre runtime.
     38 \item \emph{vanilla}: the official release of memcached, version~1.6.9.
     39 \item \emph{fibre}: a modification of vanilla which uses the thread per connection model on top of the libfibre runtime~\cite{DBLP:journals/pomacs/KarstenB20}.
    7640 \item \emph{cfa}: a modification of the fibre webserver that replaces the libfibre runtime with \CFA.
    7741\end{itemize}
    7842
    7943\subsection{Throughput} \label{memcd:tput}
    80 This experiment is done by having the clients establish 15,360 total connections, which persist for the duration of the experiment.
    81 The clients then send read and write queries with only 3\% writes (updates), attempting to follow a desired query rate, and the server responds to the desired rate as best as possible.
    82 Figure~\ref{fig:memcd:rate:qps} shows the 3 server versions at different client rates, ``Target \underline{Q}ueries \underline{P}er \underline{S}econd'', and the actual rate, ``Actual QPS'', for all three webservers.
    83 
    84 Like the experimental setup in Chapter~\ref{microbench}, each experiment is run 15 times, and for each client rate, the measured webserver rate is plotted.
    85 The solid line represents the median while the dashed and dotted lines represent the maximum and minimum respectively.
    86 For rates below 500K queries per seconds, all three webservers match the client rate.
    87 Beyond 500K, the webservers cannot match the client rate.
    88 During this interval, vanilla Memcached achieves the highest webserver throughput, with libfibre and \CFA slightly lower but very similar throughput.
    89 Overall the performance of all three webservers is very similar, especially considering that at 500K the servers have reached saturation, which is discussed more in the next section.

     49\end{figure}
     50Figure~\ref{fig:memcd:rate:qps} shows the result for the throughput of all three webservers.
     51This experiment is done by having the clients establish 15360 total connections, which persist for the duration of the experiments.
     52The clients then send requests, attempting to follow a desired request rate.
     53The servers respond to the desired rate as best they can and the difference between desired rate, ``Target \underline{Q}ueries \underline{P}er \underline{S}econd'', and the actual rate, ``Actual QPS''.
     54The results show that \CFA achieves equivalent throughput even when the server starts to reach saturation.
     55Only then does it start to fall behind slightly.
     56This is a demonstration of the \CFA runtime achieving its performance goal.
     57
     58\subsection{Tail Latency}
     59\begin{figure}
     60        \centering
     61        \input{result.memcd.rate.99th.pstex_t}
     62        \caption[Memcached Benchmark : 99th Percentile Lantency]{Memcached Benchmark : 99th Percentile Lantency\smallskip\newline 99th Percentile of the response latency as a function of \emph{desired} request rate for 15360 connections. }
    10263        \label{fig:memcd:rate:tail}
    10364\end{figure}
    104 
    105 \subsection{Tail Latency}
    106 Another popular performance metric is \newterm{tail} latency, which indicates some notion of fairness among requests across the experiment, \ie do some requests wait longer than other requests for service.
    107 Since many web applications rely on a combination of different queries made in parallel, the latency of the slowest response, \ie tail latency, can dictate a performance perception.
    108 Figure~\ref{fig:memcd:rate:tail} shows the 99th percentile latency results for the same Memcached experiment.
    109 
    110 Again, each experiment is run 15 times with the median, maximum and minimum plotted with different lines.
    111 As expected, the latency starts low and increases as the server gets close to saturation, at which point, the latency increases dramatically because the webservers cannot keep up with the connection rate so client requests are disproportionally delayed.
    112 Because of this dramatic increase, the Y axis is presented using log scale.
    113 Note that the graph shows \emph{target} query rate, the actual response rate is given in Figure~\ref{fig:memcd:rate:qps} as this is the same underlying experiment.
    114 
    115 For all three servers, the saturation point is reached before 500K queries per second, which is when throughput starts to decline among the webservers.
    116 In this experiment, all three webservers are much more distinguishable than the throughput experiment.
    117 Vanilla Memcached achieves the lowest latency until 600K, after which all the webservers are struggling to respond to client requests.
    118 \CFA begins to decline at 600K, indicating some bottleneck after saturation.
    119 Overall, all three webservers achieve micro-second latencies and the increases in latency mostly follow each other.
     65Another important performance metric to look at is \newterm{tail} latency.
     66Since many web applications rely on a combination of different requests made in parallel, the latency of the slowest response, \ie tail latency, can dictate overall performance.
     67Figure~\ref{fig:memcd:rate:tail} shows the 99th percentile latency results for the same experiment memcached experiment.
     68As is expected, the latency starts low and increases as the server gets close to saturation, point at which the latency increses dramatically.
     69Note that the figure shows \emph{target} request rate, the actual response rate is given in Figure~\ref{fig:memcd:rate:qps} as this is the same underlying experiment.
    12070
    12171\subsection{Update rate}
    122 Since Memcached is effectively a simple database, the information that is cached can be written to concurrently by multiple queries.
    123 And since writes can significantly affect performance, it is interesting to see how varying the update rate affects performance.
    124 Figure~\ref{fig:memcd:updt} shows the results for the same experiment as the throughput and latency experiment but increasing the update percentage to 5\%, 10\% and 50\%, respectively, versus the original 3\% update percentage.

    168 
    169 In the end, this experiment mostly demonstrates that the performance of Memcached is affected very little by the update rate.
    170 Indeed, since values read/written can be bigger than what can be read/written atomically, a lock must be acquired while the value is read.
    171 Hence, I believe the underlying locking pattern for reads and writes is fairly similar, if not the same.
    172 These results suggest Memcached does not attempt to optimize reads/writes using a readers-writer lock to protect each value and instead just relies on having a sufficient number of keys to limit contention.
    173 In the end, the update experiment shows that \CFA is achieving equivalent performance.

    176 The Memcached experiment does not exercise two key aspects of the \io subsystem: accept\-ing new connections and interacting with disks.
    177 On the other hand, a webserver servicing static web-pages does stress both accepting connections and disk \io by accepting tens of thousands of client requests per second where these requests return static data serviced from the file-system cache or disk.\footnote{
    178 Webservers servicing dynamic requests, which read from multiple locations and construct a response, are not as interesting since creating the response takes more time and does not exercise the runtime in a meaningfully different way.}
    179 The static webserver experiment compares NGINX~\cite{nginx} with a custom \CFA-based webserver developed for this experiment.
     114The memcached experiment has two aspects of the \io subsystem it does not exercise, accepting new connections and interacting with disks.
     115On the other hand, static webservers, servers that offer static webpages, do stress disk \io since they serve files from disk\footnote{Dynamic webservers, which construct pages as they are sent, are not as interesting since the construction of the pages do not exercise the runtime in a meaningfully different way.}.
     116The static webserver experiments will compare NGINX~\cit{nginx} with a custom webserver developped for this experiment.
    180117
    181118\subsection{\CFA webserver}
    182 The \CFA webserver is a straightforward thread-per-connection webserver, where a fixed number of \ats are created upfront (tuning parameter).
    183 Each \at calls @accept@, through @io_uring@, on the listening port and handles the incoming connection once accepted.
    184 Most of the implementation is fairly straightforward;
    185 however, the inclusion of file \io found an @io_uring@ problem that required an unfortunate workaround.
    186 
    187 Normally, webservers use @sendfile@~\cite{MAN:sendfile} to send files over a socket because it performs a direct move in the kernel from the file-system cache to the NIC, eliminating reading/writing the file into the webserver.
    188 While @io_uring@ does not support @sendfile@, it does supports @splice@~\cite{MAN:splice}, which is strictly more powerful.
    189 However, because of how Linux implements file \io, see Subsection~\ref{ononblock}, @io_uring@ must delegate splice calls to worker threads inside the kernel.
    190 As of Linux 5.13, @io_uring@ had no mechanism to restrict the number of worker threads, and therefore, when tens of thousands of splice requests are made, it correspondingly creates tens of thousands of internal \glspl{kthrd}.
    191 Such a high number of \glspl{kthrd} slows Linux significantly.
    192 Rather than abandon the experiment, the \CFA webserver was switched to nonblocking @sendfile@.
    193 However, when the nonblocking @sendfile@ returns @EAGAIN@, the \CFA server cannot block the \at because its I/O subsystem uses @io_uring@.
    194 Therefore, the \at must spin performing the @sendfile@ and yield if the call returns @EAGAIN@.
    195 This workaround works up to the saturation point, when other problems occur.
    196 
    197 At saturation, latency increases so some client connections timeout.
    198 As these clients close their connection, the server must close its corresponding side without delay so the OS can reclaim the resources used by these connections.
    199 Indeed, until the server connection is closed, the connection lingers in the CLOSE-WAIT TCP state~\cite{rfc:tcp} and the TCP buffers are preserved.
    200 However, this poses a problem using nonblocking @sendfile@ calls:
    201 the call can still block if there is insufficient memory, which can be caused by having too many connections in the CLOSE-WAIT state.\footnote{
    202 \lstinline{sendfile} can always block even in nonblocking mode if the file to be sent is not in the file-system cache, because Linux does not provide nonblocking disk I/O.}
    203 When @sendfile@ blocks, the \proc rather than the \at blocks, preventing other connections from closing their sockets.
    204 This effect results in a negative feedback where more timeouts lead to more @sendfile@ calls running out of resources.
    205 
    206 Normally, this is address by using @select@/@epoll@ to wait for sockets to have sufficient resources.
    207 However, since @io_uring@ respects nonblocking semantics, marking all sockets as non-blocking effectively circumvents the @io_uring@ subsystem entirely.
     119Unlike the memcached experiment, the webserver experiment relies on a custom designed webserver.
     120It is a simple thread-per-connection webserver where a fixed number of \ats are created upfront.
     121Each of the \at calls @accept@, through @io_uring@, on the listening port and handle the incomming connection once accepted.
     122Most of the implementation is fairly straight forward however the inclusion of file \io introduces a new challenge that had to be hacked around.
     123
     124Normally, webservers use @sendfile@\cite{MAN:sendfile} to send files over the socket.
     125@io_uring@ does not support @sendfile@, it supports @splice@\cite{MAN:splice} instead, which is strictly more powerful.
     126However, because of how linux implements file \io, see Subsection~\ref{ononblock}, @io_uring@'s implementation must delegate calls to splice to worker threads inside the kernel.
     127As of Linux 5.13, @io_uring@ caps the numer of these worker threads to @RLIMIT_NPROC@ and therefore, when tens of thousands of splice requests are made, it can create tens of thousands of \glspl{kthrd}.
     128Such a high number of \glspl{kthrd} is more than Linux can handle in this scenario so performance suffers significantly.
     129For this reason, the \CFA webserver calls @sendfile@ directly.
     130This approach works up to a certain point, but once the server approaches saturation, it leads to a new problem.
     131
     132When the saturation point of the server is attained, latency will increase and inevitably some client connections will timeout.
     133As these clients close there connections, the server must close these sockets without delay so the OS can reclaim the resources used by these connections.
     134Indeed, until they are closed on the server end, the connection will linger in the CLOSE-WAIT tcp state~\cite{rfc:tcp} and the tcp buffers will be preserved.
     135However, this poses a problem using blocking @sendfile@ calls.
     136The calls can block if they do not have suffcient memory, which can be caused by having too many connections in the CLOSE-WAIT state.
     137Since blocking in calls to @sendfile@ blocks the \proc rather than the \at, this prevents other connections from closing their sockets.
     138This leads to a vicious cycle where timeouts lead to @sendfile@ calls running out of resources, which lead to more timeouts.
     139
     140Normally, this is address by marking the sockets as non-blocking and using @epoll@ to wait for sockets to have sufficient resources.
     141However, since @io_uring@ respects non-blocking semantics marking all sockets as non-blocking effectively circumvents the @io_uring@ subsystem entirely.
    208142For this reason, the \CFA webserver sets and resets the @O_NONBLOCK@ flag before and after any calls to @sendfile@.
    209143Normally @epoll@ would also be used when these calls to @sendfile@ return @EAGAIN@, but since this would not help in the evaluation of the \CFA runtime, the \CFA webserver simply yields and retries in these cases.
    210144
    211 Interestingly, Linux 5.15 @io_uring@ introduces the ability to limit the number of worker threads that are created, through the @IORING_REGISTER_IOWQ_MAX_WORKERS@ option.
     145It is important to state that in Linux 5.15 @io_uring@ introduces the ability for users to limit the number of worker threads that are created, through the @IORING_REGISTER_IOWQ_MAX_WORKERS@ option.
    212146However, as of writing this document Ubuntu does not have a stable release of Linux 5.15.
    213147There exists versions of the kernel that are currently under testing, but these caused unrelated but nevertheless prohibitive issues in this experiment.

    217151\subsection{Benchmark Environment}
    218 Unlike the Memcached experiment, the webserver experiment is run on a heterogeneous environment.
    219 \begin{itemize}
    220 \item
     152Unlike the memcached experiment, the webserver run on a more heterogenous environment.
    221153The server runs Ubuntu 20.04.4 LTS on top of Linux Kernel 5.13.0-52.
    222 \item
    223 It has an AMD Opteron(tm) Processor 6380 running at 2.5GHz.
    224 \item
    225 Each CPU has 64 KB, 256 KiB and 8 MB of L1, L2 and L3 caches respectively.
    226 \item
    227 The computer is booted with only 8 CPUs enabled, which is sufficient to achieve line rate.
    228 \item
    229 The computer is booted with only 25GB of memory to restrict the file-system cache.
    230 \end{itemize}
    231 There are 8 client machines.
    232 \begin{itemize}
    233 \item
    234 A client runs a 2.6.11-1 SMP Linux kernel, which permits each client load-generator to run on a separate CPU.
    235 \item
    236 It has two 2.8 GHz Xeon CPUs, and four one-gigabit Ethernet cards.
    237 \item
     154It has an AMD Opteron(tm) Processor 6380 running at 2.50GHz.
     155These CPUs has only 8 \glspl{hthrd} enabled by grub, which is sufficient to achieve line rate.
     156This cpus each have 64 KB, 256 KiB and 8 MB of L1, L2 and L3 caches respectively.
     157The kernel is setup to limit the memory at 25Gb.
     158
     159The client machines each have two 2.8 GHz Xeon CPUs, and four one-gigabit Ethernet cards.
     160Each client machine runs two copies of the workload generator.
     161They run a 2.6.11-1 SMP Linux kernel, which permits each client load-generator to run on a separate CPU.
     162Since the clients outnumber the server 8-to-1, this is plenty sufficient to generate enough load for the clients not to become the bottleneck.
     163
    238164\todo{switch}
    239 \item
    240 A client machine runs two copies of the workload generator.
    241 \end{itemize}
    242 The clients and network are sufficiently provisioned to drive the server to saturation and beyond.
    243 Hence, any server effects are attributable solely to the runtime system and webserver.
    244 Finally, without restricting the server hardware resources, it is impossible to determine if a runtime system or the webserver using it has any specific design restrictions, \eg using space to reduce time.
    245 Trying to determine these restriction with large numbers of processors or memory simply means running equally large experiments, which takes longer and are harder to set up.
    246165
    247166\subsection{Throughput}
    248 To measure webserver throughput, the server computer is loaded with 21,600 files, sharded across 650 directories, occupying about 2.2GB of disk, distributed over the server's RAID-5 4-drives to achieve high throughput for disk I/O.
    249 The clients run httperf~\cite{httperf} to request a set of static files.
    250 The httperf load-generator is used with session files to simulate a large number of users and to implement a partially open-loop system.
    251 This permits httperf to produce overload conditions, generate multiple requests from persistent HTTP/1.1 connections, and include both active and inactive off periods to model browser processing times and user think times~\cite{Barford98}.
    252 
    253 The experiments are run with 16 clients, each running a copy of httperf (one copy per CPU), requiring a set of 16 log files with requests conforming to a Zipf distribution.
    254 This distribution is representative of users accessing static data through a web-browser.
    255 Each request reads a file name from its trace, establishes a connection, performs an HTTP get-request for the file name, receive the file data, close the connection, and repeat the process.
    256 Some trace elements have multiple file names that are read across a persistent connection.
    257 A client times-out if the server does not complete a request within 10 seconds.
    258 
    259 An experiment consists of running a server with request rates ranging from 10,000 to 70,000 requests per second;
    260 each rate takes about 5 minutes to complete.
    261 There is 20 seconds idle time between rates and between experiments to allow connections in the TIME-WAIT state to clear.
    262 Server throughput is measured both at peak and after saturation (\ie after peak).
    263 Peak indicates the level of client requests the server can handle and after peak indicates if a server degrades gracefully.
     167To measure the throughput of both webservers, each server is loaded with over 30,000 files making over 4.5 Gigabytes in total.
     168Each client runs httperf~\cit{httperf} which establishes a connection, does an http request for one or more files, closes the connection and repeats the process.
     169The connections and requests are made according to a Zipfian distribution~\cite{zipf}.
    264170Throughput is measured by aggregating the results from httperf of all the clients.
    265 
    266 Two workload scenarios are created by reconfiguring the server with different amounts of memory: 4 GB and 2 GB.
    267 The two workloads correspond to in-memory (4 GB) and disk-I/O (2 GB).
    268 Due to the Zipf distribution, only a small amount of memory is needed to service a significant percentage of requests.
    269 Table~\ref{t:CumulativeMemory} shows the cumulative memory required to satisfy the specified percentage of requests; e.g., 95\% of the requests come from 126.5 MB of the file set and 95\% of the requests are for files less than or equal to 51,200 bytes.
    270 Interestingly, with 2 GB of memory, significant disk-I/O occurs.
    271

    282184Figure~\ref{fig:swbsrv} shows the results comparing \CFA to NGINX in terms of throughput.
    283 These results are fairly straightforward.
     185These results are fairly straight forward.
    284186Both servers achieve the same throughput until around 57,500 requests per seconds.
    285187Since the clients are asking for the same files, the fact that the throughput matches exactly is expected as long as both servers are able to serve the desired rate.
    286188Once the saturation point is reached, both servers are still very close.
    287 NGINX achieves slightly better throughput.
    288 However, Figure~\ref{fig:swbsrv:err} shows the rate of errors, a gross approximation of tail latency, where \CFA achieves notably fewer errors once the machine reaches saturation.
    289 This suggest that \CFA is slightly more fair and NGINX may slightly sacrifice some fairness for improved throughput.

     195The throughput was made using a server with 25gb of memory, this was sufficient to hold the entire fileset in addition to all the code and data needed to run the webserver and the reste of the machine.
    308196Previous work like \cit{Cite Ashif's stuff} demonstrate that an interesting follow-up experiment is to rerun the same throughput experiment but allowing significantly less memory on the machine.
    309197If the machine is constrained enough, it will force the OS to evict files from the file cache and cause calls to @sendfile@ to have to read from disk.
    310198However, what these low memory experiments demonstrate is how the memory footprint of the webserver affects the performance.
    311 However, since what I am to evaluate in this thesis is the runtime of \CFA, I decided to forgo experiments on low memory server.

    3 The first step in evaluating this work is to test small controlled cases to ensure the basics work properly.
    4 This chapter presents five different experimental setups for evaluating the basic features of the \CFA, libfibre~\cite{libfibre}, Go, and Tokio~\cite{Tokio} schedulers.
    5 All of these systems have a \gls{uthrding} model.
    6 The goal in this chapter is show the \CFA scheduler obtains equivalent performance to other less fair schedulers through the different experiments.
    7 Note, only the code of the \CFA tests is shown;
    8 all tests in the other systems are functionally identical and available online~\cite{SchedulingBenchmarks}.
     3The first step in evaluating this work is to test-out small controlled cases to ensure the basics work properly.
     4This chapter presents five different experimental setup, evaluating some of the basic features of \CFA's scheduler.

    106\section{Benchmark Environment}\label{microenv}
    11 
    127All benchmarks are run on two distinct hardware platforms.
    138\begin{description}
    … …  
    2520\end{description}
    2621
    27 For all benchmarks, @taskset@ is used to limit the experiment to 1 NUMA node with no hyper threading.
    28 If more \glspl{hthrd} are needed, then 1 NUMA node with hyperthreading is used.
    29 If still more \glspl{hthrd} are needed, then the experiment is limited to as few NUMA nodes as needed.
    30 For the Intel machine, this means that from 1 to 24 \procs one socket and \emph{no} hyperthreading is used, and from 25 to 48 \procs still only one socket is used but \emph{with} hyperthreading.
    31 This pattern is repeated between 49 and 96, between 97 and 144, and between 145 and 192.
    32 On AMD, the same algorithm is used, but the machine only has 2 sockets.
    33 So hyperthreading\footnote{
    34 Hyperthreading normally refers specifically to the technique used by Intel, however it is often used generically to refer to any equivalent feature.}
    35 is used when the \proc count reach 65 and 193.
     22For all benchmarks, @taskset@ is used to limit the experiment to 1 NUMA Node with no hyper threading.
     23If more \glspl{hthrd} are needed, then 1 NUMA Node with hyperthreading is used.
     24If still more \glspl{hthrd} are needed, then the experiment is limited to as few NUMA Nodes as needed.
    3625
    3726The limited sharing of the last-level cache on the AMD machine is markedly different than the Intel machine.
    38 Indeed, while on both architectures L2 cache misses that are served by L3 caches on a different CPU incur a significant latency, on the AMD it is also the case that cache misses served by a different L3 instance on the same CPU also incur high latency.
    39 
    40 \section{Experimental setup}
    41 
    42 Each experiment is run 15 times varying the number of processors depending on the two different computers.
    43 All experiments gather throughput data and secondary data for scalability or latency.
    44 The data is graphed using a solid and two dashed lines representing the median, maximum and minimum result respectively, where the minimum/maximum lines are referred to as the \emph{extremes}.\footnote{
    45 An alternative display is to use error bars with min/max as the bottom/top for the bar.
    46 However, this approach is not truly an error bar around a mean value and I felt the connected lines are easier to read.}
    47 This graph presentation offers an overview of the distribution of the results for each experiment.
    48 
    49 For each experiment, four graphs are generated showing traditional throughput on the top row and \newterm{scalability} or \newterm{latency} on the bottom row (peek ahead to Figure~\ref{fig:cycle:jax}).
    50 Scalability uses the same data as throughput but the Y axis is calculated as the number of \procs over the throughput.
    51 In this representation, perfect scalability should appear as a horizontal line, \eg, if doubling the number of \procs doubles the throughput, then the relation stays the same.
    52 
    53 The left column shows results for 100 cycles per \proc, enough cycles to always keep every \proc busy.
    54 The right column shows results for 1 cycle per \proc, where the ready queues are expected to be near empty most of the time.
    55 The distinction between 100 and 1 cycles is meaningful because the idle sleep subsystem is expected to matter only in the right column, where spurious effects can cause a \proc to run out of work temporarily.
    56 
    57 \section{Cycle}
    58 
    59 The most basic evaluation of any ready queue is the latency needed to push and pop one element from the ready queue.
    60 Since these two operations also describe a @yield@ operation, many systems use this operation as the fundamental benchmark.
    61 However, yielding can be treated as a special case by optimizing it away since the number of ready \ats does not change.
    62 Hence, systems that perform this optimization have an artificial performance benefit because the yield becomes a \emph{nop}.
    63 For this reason, I designed a different push/pop benchmark, called \newterm{Cycle Benchmark}.
    64 This benchmark arranges a number of \ats into a ring, as seen in Figure~\ref{fig:cycle}, where the ring is a circular singly-linked list.
    65 At runtime, each \at unparks the next \at before parking itself.
    66 Unparking the next \at pushes that \at onto the ready queue while the ensuing park leads to a \at being popped from the ready queue.
    67 
     27Indeed, while on both architectures L2 cache misses that are served by L3 caches on a different CPU incur a significant latency, on the AMD it is also the case that cache misses served by a different L3 instance on the same CPU still incur high latency.
     28
     29
     30\section{Cycling latency}
    6831\begin{figure}
    6932        \centering
    … …  
    7235        \label{fig:cycle}
    7336\end{figure}
    74 
    75 Therefore, the underlying runtime cannot rely on the number of ready \ats staying constant over the duration of the experiment.
    76 In fact, the total number of \ats waiting on the ready queue is expected to vary because of the race between the next \at unparking and the current \at parking.
    77 That is, the runtime cannot anticipate that the current task immediately parks.
    78 As well, the size of the cycle is also decided based on this race, \eg a small cycle may see the chain of unparks go full circle before the first \at parks because of time-slicing or multiple \procs.
    79 If this happens, the scheduler push and pop are avoided and the results of the experiment are skewed.
    80 (Note, an unpark is like a V on a semaphore, so the subsequent park (P) may not block.)
    81 Every runtime system must handle this race and cannot optimized away the ready-queue pushes and pops.
     37The most basic evaluation of any ready queue is to evaluate the latency needed to push and pop one element from the ready queue.
     38Since these two operation also describe a @yield@ operation, many systems use this operation as the most basic benchmark.
     39However, yielding can be treated as a special case and some aspects of the scheduler can be optimized away since the number of ready \ats does not change.
     40Not all systems perform this type of optimization, but those that do have an artificial performance benefit because the yield becomes a \emph{nop}.
     41For this reason, I chose a different first benchmark, called \newterm{Cycle Benchmark}.
     42This benchmark arranges a number of \ats into a ring, as seen in Figure~\ref{fig:cycle}, where the ring is a circular singly-linked list.
     43At runtime, each \at unparks the next \at before parking itself.
     44Unparking the next \at pushes that \at onto the ready queue while the ensuing park leads to a \at being popped from the ready queue.
     45
     46Hence, the underlying runtime cannot rely on the number of ready \ats staying constant over the duration of the experiment.
     47In fact, the total number of \ats waiting on the ready queue is expected to vary because of the delay between the next \at unparking and the current \at parking.
     48That is, the runtime cannot anticipate that the current task will immediately park.
     49As well, the size of the cycle is also decided based on this delay.
     50Note that, an unpark is like a V on a semaphore, so the subsequent park (P) may not block.
     51If this happens, the scheduler push and pop are avoided and the results of the experiment would be skewed.
     52Because of time-slicing or because cycles can be spread over multiple \procs, a small cycle may see the chain of unparks go full circle before the first \at parks.
     53Every runtime system must handle this race and but cannot optimized away the ready-queue pushes and pops if the cycle is long enough.
    8254To prevent any attempt of silently omitting ready-queue operations, the ring of \ats is made big enough so the \ats have time to fully park before being unparked again.
    8355Finally, to further mitigate any underlying push/pop optimizations, especially on SMP machines, multiple rings are created in the experiment.
    8456
    85 Figure~\ref{fig:cycle:code} shows the pseudo code for this benchmark, where each cycle has 5 \ats.
     57Figure~\ref{fig:cycle:code} shows the pseudo code for this benchmark.
    8658There is additional complexity to handle termination (not shown), which requires a binary semaphore or a channel instead of raw @park@/@unpark@ and carefully picking the order of the @P@ and @V@ with respect to the loop condition.

    167 \subsection{Results}
    168 
    169 For the Intel architecture, Figure~\ref{fig:cycle:jax}:
    170 \begin{itemize}
    171 \item
    172 For 100 cycles per \proc (first column), \CFA, Go and Tokio all obtain effectively the same throughput performance.
     137Figure~\ref{fig:cycle:jax} and Figure~\ref{fig:cycle:nasus} shows the throughput as a function of \proc count on Intel and AMD respectively, where each cycle has 5 \ats.
     138The graphs show traditional throughput on the top row and \newterm{scalability} on the bottom row.
     139Where scalability uses the same data but the Y axis is calculated as the number of \procs over the throughput.
     140In this representation, perfect scalability should appear as a horizontal line, \eg, if doubling the number of \procs doubles the throughput, then the relation stays the same.
     141The left column shows results for 100 cycles per \proc, enough cycles to always keep every \proc busy.
     142The right column shows results for only 1 cycle per \proc, where the ready queues are expected to be near empty at all times.
     143The distinction is meaningful because the idle sleep subsystem is expected to matter only in the right column, where spurious effects can cause a \proc to run out of work temporarily.
     144
     145The experiment was run 15 times for each series and processor count and the \emph{$\times$}s on the graph show all of the results obtained.
     146Each series also has a solid and two dashed lines highlighting the median, maximum and minimum result respectively.
     147This presentation offers an overview of the distribution of the results for each series.
     148
     149The experimental setup uses taskset to limit the placement of \glspl{kthrd} by the operating system.
     150As mentioned in Section~\ref{microenv}, the experiement is setup to prioritize running on 2 \glspl{hthrd} per core before running on multiple sockets.
     151For the Intel machine, this means that from 1 to 24 \procs, one socket and \emph{no} hyperthreading is used and from 25 to 48 \procs, still only one socket but \emph{with} hyperthreading.
     152This pattern is repeated between 49 and 96, between 97 and 144, and between 145 and 192.
     153On AMD, the same algorithm is used, but the machine only has 2 sockets.
     154So hyperthreading\footnote{Hyperthreading normally refers specifically to the technique used by Intel, however here it is loosely used to refer to AMD's equivalent feature.} is used when the \proc count reach 65 and 193.
     155
     156Figure~\ref{fig:cycle:jax:ops} and Figure~\ref{fig:cycle:jax:ns} show that for 100 cycles per \proc, \CFA, Go and Tokio all obtain effectively the same performance.
    173157Libfibre is slightly behind in this case but still scales decently.
    174 As a result of the \gls{kthrd} placement, additional \procs from 25 to 48 offer less performance improvement (flatting of the line) for all runtimes.
    175 As expected, this pattern repeats again between \proc count 72 and 96.
    176 \item
    177 For 1 cycle per \proc, \CFA and Tokio obtain very similar results overall, but Tokio shows more variations in the results.
    178 Go achieves slightly better performance.
    179 Interestingly, libfibre achieves better performance with 1 cycle.
    180 \end{itemize}
    181 
    182 For the AMD architecture, Figure~\ref{fig:cycle:nasus}, the results show the same story as on the Intel, with close to double the performance overall but with slightly increased variation.
    183 The different performance improvements and plateaus are due to cache topology and appear at the expected \proc counts of 64, 128 and 192, for the same reasons as on Intel.
    184 \begin{itemize}
    185 \item
    186 For 100 cycles per \proc, unlike Intel, all 4 runtimes achieve very similar throughput and scalability.
    187 \item
    188 For 1 cycle per \proc, unlike on Intel, Tokio and Go have the same throughput performance, while \CFA is slightly slower.
    189 Again, the same performance increase for libfibre is visible.
    190 \end{itemize}
    191 Note, I did not investigate the libfibre performance boost for 1 cycle in this experiment.
    192 
    193 The conclusion from both architectures is that all of the compared runtime have fairly equivalent performance for this micro-benchmark.
    194 Clearly, the pathological case with 1 \at per \proc, can affect fairness algorithms managing mostly idle processors, \eg \CFA, but only at high core counts.
    195 For this case, \emph{any} helping is likely to cause a cascade of \procs running out of work and attempting to steal.
    196 For this experiment, the \CFA scheduler has achieved the goal of obtaining equivalent performance to other less fair schedulers, except for very unusual workloads.
     158As a result of the \gls{kthrd} placement, we can see that additional \procs from 25 to 48 offer less performance improvements for all runtimes.
     159As expected, this pattern repeats between \proc count 72 and 96.
     160The performance goal of \CFA is to obtain equivalent performance to other, less fair schedulers and that is what results show.
     161Figure~\ref{fig:cycle:jax:ops} and \ref{fig:cycle:jax:ns} show very good throughput and scalability for all runtimes.
     162
     163When running only a single cycle, the story is slightly different.
     164\CFA and tokio obtain very smiliar results overall, but tokio shows notably more variations in the results.
     165While \CFA, Go and tokio achive equivalent performance with 100 cycles per \proc, with only 1 cycle per \proc Go achieves slightly better performance.
     166This difference in throughput and scalability is due to the idle-sleep mechanism.
     167With very few cycles, stealing or helping can cause a cascade of tasks migration and trick \proc into very short idle sleeps.
     168Both effect will negatively affect performance.
     169
     170An interesting and unusual result is that libfibre achieves better performance with fewer cycle.
     171This suggest that the cascade effect is never present in libfibre and that some bottleneck disappears in this context.
     172However, I did not investigate this result any deeper.
     173
     174Figure~\ref{fig:cycle:nasus} show a similar story happening on AMD as it does on Intel.
     175The different performance improvements and plateaus due to cache topology appear at the expected \proc counts of 64, 128 and 192, for the same reasons as on Intel.
     176Unlike Intel, on AMD all 4 runtimes achieve very similar throughput and scalability for 100 cycles per \proc.
     177
     178In the 1 cycle per \proc experiment, the same performance increase for libfibre is visible.
     179However, unlike on Intel, tokio achieves the same performance as Go rather than \CFA.
     180This leaves \CFA trailing behind in this particular case, but only at hight core counts.
     181Presumably this is because in this case, \emph{any} helping is likely to cause a cascade of \procs running out of work and attempting to steal.
     182Since this effect is only problematic in cases with 1 \at per \proc it is not very meaningful for the general performance.
     183
     184The conclusion from both architectures is that all of the compared runtime have fairly equivalent performance in this scenario.
     185Which demonstrate that in this case \CFA achieves equivalent performance.

    198187\section{Yield}
    199 
    200188For completion, the classic yield benchmark is included.
    201 Here, the throughput is dominated by the mechanism used to handle the @yield@ function.
    202 Figure~\ref{fig:yield:code} shows pseudo code for this benchmark, where the cycle @wait/next.wake@ is replaced by @yield@.
     189This benchmark is simpler than the cycle test: it creates many \ats that call @yield@.
    203190As mentioned, this benchmark may not be representative because of optimization shortcuts in @yield@.
    204 The only interesting variable in this benchmark is the number of \ats per \procs, where ratios close to 1 means the ready queue(s) can be empty, which again puts a strain on the idle-sleep handling.
     191The only interesting variable in this benchmark is the number of \ats per \procs, where ratios close to 1 means the ready queue(s) can be empty.
     192This scenario can put a strain on the idle-sleep handling compared to scenarios where there is plenty of work.
     193Figure~\ref{fig:yield:code} shows pseudo code for this benchmark, where the @wait/next.wake@ is replaced by @yield@.

    252 \subsection{Results}
    253 
    254 Figures~\ref{fig:yield:jax} and~\ref{fig:yield:nasus} show the same throughput graphs as @cycle@ on Intel and AMD, respectively.
    255 Note, the Y-axis on the yield graph for Intel is twice as large as the Intel cycle-graph.
    256 A visual glance between the cycle and yield graphs confirms my claim that the yield benchmark is unreliable.
    257 
    258 For the Intel architecture, Figure~\ref{fig:yield:jax}:
    259 \begin{itemize}
    260 \item
    261 \CFA has no special handling for @yield@, but this experiment requires less synchronization than the @cycle@ experiment.
    262 Hence, the @yield@ throughput and scalability graphs for both 100 and 1 cycles/tasks per processor have similar shapes to the corresponding @cycle@ graphs.
    263 The only difference is sightly better performance for @yield@ because of less synchronization.
    264 As for @cycle@, the cost of idle sleep also comes into play in a very significant way in Figure~\ref{fig:yield:jax:low:ns}, where the scaling is not flat.
    265 \item
    266 libfibre has special handling for @yield@ using the fact that the number of ready fibres does not change, and therefore, by-passing the idle-sleep mechanism entirely.
    267 Additionally, when only running 1 \at per \proc, libfibre optimizes further, and forgoes the context-switch entirely.
    268 Hence, libfibre behaves very differently in the cycle and yield benchmarks, with a 4 times increase in performance for 100 cycles/tasks and an 8 times increase for 1 cycle/task.
    269 \item
    270 Go has special handling for @yield@ by putting a yielding goroutine on a secondary global ready-queue, giving it lower priority.

     273The throughput is dominated by the mechanism used to handle the @yield@.
     274\CFA does not have special handling for @yield@ but the experiment requires less synchronization.
     275As a result achieves better performance than the cycle benchmark, but still comparable.
     276
     277When the number of \ats is reduce to 1 per \proc, the cost of idle sleep also comes into play in a very significant way.
     278If anything causes a \at migration, where two \ats end-up on the same ready-queue, work-stealing will start occuring and could cause several \ats to shuffle around.
     279In the process, several \procs can go to sleep transiently if they fail to find where the \ats were shuffled to.
     280In \CFA, spurious bursts of latency can trick a \proc into helping, triggering this effect.
     281However, since user-level threading with equal number of \ats and \procs is a somewhat degenerate case, especially when context-switching very often, this result is not particularly meaningful and is only included for completness.
     282
     283Libfibre uses the fact that @yield@ doesn't change the number of ready fibres and by-passes the idle-sleep mechanism entirely, producing significantly better throughput.
     284Additionally, when only running 1 \at per \proc, libfibre optimizes further and forgoes the context-switch entirely.
     285This results in incredible performance results comparing to the other runtimes.
     286
     287In stark contrast with libfibre, Go puts yielding goroutines on a secondary global ready-queue, giving them lower priority.
    271288The result is that multiple \glspl{hthrd} contend for the global queue and performance suffers drastically.
    272 Hence, Go behaves very differently in the cycle and yield benchmarks, with a complete performance collapse in @yield@ for both 100 and 1 cycles/tasks.
    273 \item
    274 Tokio has a similar performance collapse after 16 processors, and therefore, its special @yield@ handling is probably related to a Go-like scheduler problem and/or a \CFA idle-sleep problem.
    275 (I did not dig through the Rust code to ascertain the exact reason for the collapse.)

    307 
    308 For the AMD architecture, Figure~\ref{fig:yield:nasus}, the results show the same story as on the Intel, with slightly increased variations.
    309 Also, some transition points on the X-axis differ because of the architectures, like at 16 versus 24 processors.
    310 
    311 It is difficult to draw conclusions for this benchmark when runtime system treat @yield@ so differently.
    312 The win for \CFA is its consistency between the cycle and yield benchmarks making it simpler for programmers to use and understand, \ie the \CFA semantics match with programmer intuition.
     289Based on the scalability, Tokio obtains the similarly poor performance and therefore it is likely it handles @yield@ in a similar fashion.
     290However, it must be doing something different since it does scale at low \proc count.
     291
     292Again, Figure~\ref{fig:yield:nasus} show effectively the same story happening on AMD as it does on Intel.
     293\CFA fairs slightly better with many \ats per \proc, but the performance is satisfactory on both architectures.
     294
     295Since \CFA obtains the same satisfactory performance as the previous benchmark this is still a success, albeit a less meaningful one.

    315298\section{Churn}
    316 
    317299The Cycle and Yield benchmark represent an \emph{easy} scenario for a scheduler, \eg an embarrassingly parallel application.
    318300In these benchmarks, \ats can be easily partitioned over the different \procs upfront and none of the \ats communicate with each other.
    319301
    320 The Churn benchmark represents more chaotic executions, where there is more communication among \ats but no relationship between the last \proc on which a \at ran and blocked and the \proc that subsequently unblocks it.
    321 With processor-specific ready-queues, when a \at is unblocked by a different \proc that means the unblocking \proc must either ``steal'' the \at from another processor or find it on a remote queue.
    322 This dequeuing results in either contention on the remote queue and/or \glspl{rmr} on the \at data structure.
    323 Hence, this benchmark has performance dominated by the cache traffic as \proc are constantly accessing the each other's data.
    324 In either case, this benchmark aims to measure how well a scheduler handles these cases, since both cases can lead to performance degradation if not handled correctly.
     302The Churn benchmark represents more chaotic executions, where there is more communication among \ats but no apparent relation between the last \proc on which a \at ran and blocked, and the \proc that subsequently unblocks it.
     303With processor-specific ready-queues, when a \at is unblocked by a different \proc that means the unblocking \proc must either ``steal'' the \at from another processor or place it on a remote queue.
     304This enqueuing results in either contention on the remote queue and/or \glspl{rmr} on the \at data structure.
     305In either case, this benchmark aims to measure how well each scheduler handles these cases, since both cases can lead to performance degradation if not handled correctly.
    325306
    326307This benchmark uses a fixed-size array of counting semaphores.
    327 Each \at picks a random semaphore, @V@s it to unblock any waiting \at, and then @P@s (maybe blocks) the \ats on the semaphore.
     308Each \at picks a random semaphore, @V@s it to unblock any \at waiting, and then @P@s on the semaphore.
    328309This creates a flow where \ats push each other out of the semaphores before being pushed out themselves.
    329 For this benchmark to work, the number of \ats must be equal or greater than the number of semaphores plus the number of \procs;
    330 \eg if there are 10 semaphores and 5 \procs, but only 3 \ats, all 3 \ats can block (P) on a random semaphore and now there is no \ats to unblock (V) them.
     310For this benchmark to work, the number of \ats must be equal or greater than the number of semaphores plus the number of \procs.
    331311Note, the nature of these semaphores mean the counter can go beyond 1, which can lead to nonblocking calls to @P@.
    332312Figure~\ref{fig:churn:code} shows pseudo code for this benchmark, where the @yield@ is replaced by @V@ and @P@.

     393Figure~\ref{fig:churn:jax} and Figure~\ref{fig:churn:nasus} show the throughput as a function of \proc count on Intel and AMD respectively.
     394It uses the same representation as the previous benchmark : 15 runs where the dashed line show the extremums and the solid line the median.
    386395The performance cost of crossing the cache boundaries is still visible at the same \proc count.
    387 
     396However, this benchmark has performance dominated by the cache traffic as \proc are constantly accessing the eachother's data.
    388397Scalability is notably worst than the previous benchmarks since there is inherently more communication between processors.
    389398Indeed, once the number of \glspl{hthrd} goes beyond a single socket, performance ceases to improve.
    390399An interesting aspect to note here is that the runtimes differ in how they handle this situation.
    391400Indeed, when a \proc unparks a \at that was last run on a different \proc, the \at could be appended to the ready-queue local \proc or to the ready-queue of the remote \proc, which previously ran the \at.
    392 \CFA, Tokio and Go all use the approach of unparking to the local \proc while Libfibre unparks to the remote \proc.
     401\CFA, tokio and Go all use the approach of unparking to the local \proc while Libfibre unparks to the remote \proc.
    393402In this particular benchmark, the inherent chaos of the benchmark in addition to small memory footprint means neither approach wins over the other.

    426404Like for the cycle benchmark, here all runtimes achieve fairly similar performance.
    … …  
    428406Beyond that performance starts to suffer from increased caching costs.
    429407
    430 Indeed on Figures~\ref{fig:churn:jax:ops} and \ref{fig:churn:jax:ns} show that with 1 and 100 \ats per \proc, \CFA, libfibre, Go and Tokio achieve effectively equivalent performance for most \proc count.

    431409
    432410However, Figure~\ref{fig:churn:nasus} again shows a somewhat different story on AMD.
    433 While \CFA, libfibre, and Tokio achieve effectively equivalent performance for most \proc count, Go starts with better scaling at very low \proc counts but then performance quickly plateaus, resulting in worse performance at higher \proc counts.
     411While \CFA, libfibre, and tokio achieve effectively equivalent performance for most \proc count, Go starts with better scaling at very low \proc counts but then performance quickly plateaus, resulting in worse performance at higher \proc counts.
    434412This performance difference is visible at both high and low \at counts.
    435413
    … …  
    442420As second possible explanation is that Go may sometimes use the heap when allocating variables based on the result of escape analysis of the code.
    443421It is possible that variables that should be placed on the stack are placed on the heap.
    444 This could cause extra pointer chasing in the benchmark, heightening locality effects.
     422This could cause extra pointer chasing in the benchmark, heightning locality effects.
    445423Depending on how the heap is structure, this could also lead to false sharing.
    446424
    447425The objective of this benchmark is to demonstrate that unparking \ats from remote \procs do not cause too much contention on the local queues.
    448 Indeed, the fact all runtimes achieve some scaling at lower \proc count demonstrate that migrations do not need to be serialized.
     426Indeed, the fact all runtimes achieve some scaling at lower \proc count demontrate that migrations do not need to be serialized.
    449427Again these result demonstrate \CFA achieves satisfactory performance.

    508468In both variations, before @V@ing the semaphore, each \at increment random cells inside the array.

     547Otherwise the results are similar to the churn benchmark, with lower throughtput due to the array processing.
    589548Presumably the reason why Go trails behind are the same as in Figure~\ref{fig:churn:nasus}.

    613572In both flavours, the experiment effectively measures how long it takes for all \ats to run once after a given synchronization point.
    614573In an ideal scenario where the scheduler is strictly FIFO, every thread would run once after the synchronization and therefore the delay between leaders would be given by:
    615 $ \frac{CSL + SL}{NP - 1}$, where $CSL$ is the context switch latency, $SL$ is the cost for enqueueing and dequeuing a \at and $NP$ is the number of \procs.
     574$ \frac{CSL + SL}{NP - 1}$, where $CSL$ is the context switch latency, $SL$ is the cost for enqueuing and dequeuing a \at and $NP$ is the number of \procs.
    616575However, if the scheduler allows \ats to run many times before other \ats are able to run once, this delay will increase.
    617576The semaphore version is an approximation of the strictly FIFO scheduling, where none of the \ats \emph{attempt} to run more than once.
    618577The benchmark effectively provides the fairness guarantee in this case.
    619 In the yielding version however, the benchmark provides no such guarantee, which means the scheduler has full responsibility and any unfairness will be measurable.

     645The takeaway of this experiement is the presence of very large differences.
    688646The semaphore variation is denoted ``Park'', where the number of \ats dwindles down as the new leader is acknowledged.
    689647The yielding variation is denoted ``Yield''.
    690 The experiment was only run for the extremes of the number of cores since the scaling per core behaves like previous experiments.
     648The experiement was only run for the extremums of the number of cores since the scaling per core behaves like previous experiements.
    691649This experiments clearly demonstrate that while the other runtimes achieve similar performance in previous benchmarks, here \CFA achieves significantly better fairness.
    692650The semaphore variation serves as a control group, where all runtimes are expected to transfer leadership fairly quickly.

    694652Figure~\ref{fig:transfer:res} shows that while Go and Tokio are slower, all runtime achieve decent latency.
    695653However, the yielding variation shows an entirely different picture.
    696 Since libfibre and Tokio have a traditional work-stealing scheduler, \procs that have \ats on their local queues will never steal from other \procs.
    697 The result is that the experiment simply does not complete for these runtime.

    698656Without \procs stealing from the \proc running the leader, the experiment will simply never terminate.

     657Go manages to complete the experiement because it adds preemption on top of classic work-stealing.

    5050It can therefore be desirable for schedulers to support \ats with identical priorities and/or automatically setting and adjusting priorities for \ats.
    5151Most common operating systems use some variant on priorities with overlaps and dynamic priority adjustments.
    52 For example, Microsoft Windows uses a pair of priorities~\cite{win:priority}, one specified by users out of ten possible options and one adjusted by the system.

    138 In~\cite{russinovich2009windows}, Chapter 1 section ``Processes, Threads, and Jobs''\todo{Look up section number.} discusses the scheduling policy more in depth.
    139 Multicore scheduling is based on a combination of priorities and preferred \proc.
    140 Each \at is assigned an initial processor using a round-robin policy, called the \at's \newterm{ideal} \proc.
    141 \Glspl{at} are distributed among the \procs according to their priority, preferring to match \ats to their ideal \proc and then to the last \proc they ran on.
    142 This approach is a variation of work stealing, where the stealing \proc restore the \at to its original \proc after running it, but mixed with priorities.

    141141In the worst case, where all \glspl{thrd} are consistently blocking on \io, it devolves into 1-to-1 threading.
    142142However, regardless of the frequency of \io operations, it achieves the fundamental goal of not blocking \glspl{proc} when \glspl{thrd} are ready to run.
    143 This approach is used by languages like Go~\cite{GITHUB:go}, frameworks like libuv~\cite{libuv}, and web servers like Apache~\cite{apache} and NGINX~\cite{nginx}, since it has the advantage that it can easily be used across multiple operating systems.
