r4fee301 r0c40bfe 1 1 \chapter{Macro-Benchmarks}\label{macrobench} 2 The previous chapter has demonstrated that the scheduler achieves its performance goal in small and controlled scenario. 3 The next step is then to demonstrate that this stays true in more realistic and complete scenarios. 4 This chapter presents two flavours of webservers that demonstrate that \CFA performs competitively with production environments. 5 6 Webservers where chosen because they offer fairly simple applications that are still useful as standalone products. 7 Furthermore, webservers are generally amenable to parallelisation since their workloads are mostly homogenous. 8 They therefore offer a stringent performance benchmark for \CFA. 9 Indeed existing solutions are likely to have close to optimal performance while the homogeneity of the workloads mean the additional fairness is not needed. 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. 10 11 11 12 \section{Memcached} 12 Memcached~\cite{memcached} is an in memory key-value store that isused in many production environments, \eg \cite{atikoglu2012workload}.13 This also server also has the notable added benefit that there exists a full-featured front-end for performance testingcalled @mutilate@~\cite{GITHUB:mutilate}.14 Experimenting on memcached allows for a simple test of the \CFA runtime as a whole, it will exercisethe scheduler, the idle-sleep mechanism, as well the \io subsystem for sockets.15 This experiment does not exercise the \io subsytem with regards to disk operations.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. 16 17 17 18 \subsection{Benchmark Environment} 18 These experiments are run on a cluster of homogenous Supermicro SYS-6017R-TDF compute nodes with the following characteristics: 19 The Memcached experiments are run on a cluster of homogeneous Supermicro SYS-6017R-TDF compute nodes with the following characteristics. 20 \begin{itemize} 21 \item 19 22 The server runs Ubuntu 20.04.3 LTS on top of Linux Kernel 5.11.0-34. 23 \item 20 24 Each node has 2 Intel(R) Xeon(R) CPU E5-2620 v2 running at 2.10GHz. 25 \item 21 26 These CPUs have 6 cores per CPUs and 2 \glspl{hthrd} per core, for a total of 24 \glspl{hthrd}. 22 The cpus each have 384 KB, 3 MB and 30 MB of L1, L2 and L3 caches respectively. 27 \item 28 The CPUs each have 384 KB, 3 MB and 30 MB of L1, L2 and L3 caches respectively. 29 \item 23 30 Each node is connected to the network through a Mellanox 10 Gigabit Ethernet port. 24 The network route uses 1 Mellanox SX1012 10/40 Gigabit Ethernet cluster switch. 25 26 \subsection{Memcached with threads per connection} 27 Comparing against memcached using a user-level runtime only really make sense if the server actually uses this threading model. 28 Indeed, 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 30 One 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. 31 This models adds flexibility to the implementation, as the serving logic can now block on user-level primitives without affecting other connections. 32 33 Memcached 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}. 34 Therefore this version can both be compared to the original version and to a port to the \CFA runtime. 35 36 As such, this memcached experiment compares 3 different varitions of memcached: 37 \begin{itemize} 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}. 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. 40 76 \item \emph{cfa}: a modification of the fibre webserver that replaces the libfibre runtime with \CFA. 41 77 \end{itemize} 42 78 43 79 \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. 90

Figure~\ref{fig:memcd:rate:qps} shows the result for the throughput of all three webservers. 51 This experiment is done by having the clients establish 15360 total connections, which persist for the duration of the experiments. 52 The clients then send requests, attempting to follow a desired request rate. 53 The 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''. 54 The results show that \CFA achieves equivalent throughput even when the server starts to reach saturation. 55 Only then does it start to fall behind slightly. 56 This is a demonstration of the \CFA runtime achieving its performance goal. 57 58 \subsection{Tail Latency} 59

to look at is \newterm{tail} latency. 66 Since 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. 67 Figure~\ref{fig:memcd:rate:tail} shows the 99th percentile latency results for the same experiment memcached experiment. 68 As is expected, the latency starts low and increases as the server gets close to saturation, point at which the latency increses dramatically. 69 Note 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. 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. 70 120 71 121 \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. 125 72 126 \begin{figure} 73 \centering 74 \subfloat[][Throughput]{ 75 \input{result.memcd.forall.qps.pstex_t} 76 } 77 78 \subfloat[][Latency]{

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. 112 174 113 175 \section{Static Web-Server} 114 The memcached experiment has two aspects of the \io subsystem it does not exercise, accepting new connections and interacting with disks. 115 On 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.}. 116 The static webserver experiments will compare NGINX~\cit{nginx} with a custom webserver developped for this experiment. 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. 117 180 118 181 \subsection{\CFA webserver} 119 Unlike the memcached experiment, the webserver experiment relies on a custom designed webserver. 120 It is a simple thread-per-connection webserver where a fixed number of \ats are created upfront. 121 Each of the \at calls @accept@, through @io_uring@, on the listening port and handle the incomming connection once accepted. 122 Most of the implementation is fairly straight forward however the inclusion of file \io introduces a new challenge that had to be hacked around. 123 124 Normally, 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. 126 However, 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. 127 As 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}. 128 Such a high number of \glspl{kthrd} is more than Linux can handle in this scenario so performance suffers significantly. 129 For this reason, the \CFA webserver calls @sendfile@ directly. 130 This approach works up to a certain point, but once the server approaches saturation, it leads to a new problem. 131 132 When the saturation point of the server is attained, latency will increase and inevitably some client connections will timeout. 133 As these clients close there connections, the server must close these sockets without delay so the OS can reclaim the resources used by these connections. 134 Indeed, 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. 135 However, this poses a problem using blocking @sendfile@ calls. 136 The calls can block if they do not have suffcient memory, which can be caused by having too many connections in the CLOSE-WAIT state. 137 Since blocking in calls to @sendfile@ blocks the \proc rather than the \at, this prevents other connections from closing their sockets. 138 This leads to a vicious cycle where timeouts lead to @sendfile@ calls running out of resources, which lead to more timeouts. 139 140 Normally, this is address by marking the sockets as non-blocking and using @epoll@ to wait for sockets to have sufficient resources. 141 However, since @io_uring@ respects non-blocking semantics marking all sockets as non-blocking effectively circumvents the @io_uring@ subsystem entirely. 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. 142 208 For this reason, the \CFA webserver sets and resets the @O_NONBLOCK@ flag before and after any calls to @sendfile@. 143 209 Normally @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. 144 210 145 I t is important to state that in Linux 5.15 @io_uring@ introduces the ability for usersto limit the number of worker threads that are created, through the @IORING_REGISTER_IOWQ_MAX_WORKERS@ option.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. 146 212 However, as of writing this document Ubuntu does not have a stable release of Linux 5.15. 147 213 There exists versions of the kernel that are currently under testing, but these caused unrelated but nevertheless prohibitive issues in this experiment. … … 150 216 151 217 \subsection{Benchmark Environment} 152 Unlike the memcached experiment, the webserver run on a more heterogenous environment. 218 Unlike the Memcached experiment, the webserver experiment is run on a heterogeneous environment. 219 \begin{itemize} 220 \item 153 221 The server runs Ubuntu 20.04.4 LTS on top of Linux Kernel 5.13.0-52. 154 It has an AMD Opteron(tm) Processor 6380 running at 2.50GHz. 155 These CPUs has only 8 \glspl{hthrd} enabled by grub, which is sufficient to achieve line rate. 156 This cpus each have 64 KB, 256 KiB and 8 MB of L1, L2 and L3 caches respectively. 157 The kernel is setup to limit the memory at 25Gb. 158 159 The client machines each have two 2.8 GHz Xeon CPUs, and four one-gigabit Ethernet cards. 160 Each client machine runs two copies of the workload generator. 161 They run a 2.6.11-1 SMP Linux kernel, which permits each client load-generator to run on a separate CPU. 162 Since the clients outnumber the server 8-to-1, this is plenty sufficient to generate enough load for the clients not to become the bottleneck. 163 222 \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 164 238 \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. 165 246 166 247 \subsection{Throughput} 167 To measure the throughput of both webservers, each server is loaded with over 30,000 files making over 4.5 Gigabytes in total. 168 Each 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. 169 The connections and requests are made according to a Zipfian distribution~\cite{zipf}. 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. 170 264 Throughput 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. 271 272 \begin{table} 273 \caption{Cumulative memory for requests by file size} 274 \label{t:CumulativeMemory} 275 \begin{tabular}{r|rrrrrrrr} 276 \% Requests & 10 & 30 & 50 & 70 & 80 & 90 & \textbf{95} & 100 \\ 277 Memory (MB) & 0.5 & 1.5 & 8.4 & 12.2 & 20.1 & 94.3 & \textbf{126.5} & 2,291.6 \\ 278 File Size (B)

throughput. 283 These results are fairly straightforward. 284 Both servers achieve the same throughput until around 57,500 requests per seconds. 285 Since 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. 286 Once 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. 290 It demonstrate that the \CFA webserver described above is able to match the performance of NGINX up-to and beyond the saturation point of the machine. 291 171 292 \begin{figure} 172 293 \subfloat[][Throughput]{ 173 \

until around 57,500 requests per seconds.187 Since 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

sacrifice some fairness for improved throughtput.192 It demonstrate that the \CFA webserver described above is able to match the performance of NGINX up-to and beyond the saturation point of the machine.193 305 194 306 \subsection{Disk Operations} 195 The 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 rest eof the machine.307 The 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 rest of the machine. 196 308 Previous 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. 197 309 If 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. 198 310 However, what these low memory experiments demonstrate is how the memory footprint of the webserver affects the performance. 199 However, since what I am to evaluate in this thesis is the runtime of \CFA, I d iceded to forgo experiments on low memory server.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. 200 312 The implementation of the webserver itself is simply too impactful to be an interesting evaluation of the underlying runtime. -

presents five different experimental setup, evaluating some of the basic features of \CFA's scheduler. 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}. 5 9 6 10 \section{Benchmark Environment}\label{microenv} 11 7 12 All benchmarks are run on two distinct hardware platforms. 8 13 \begin{description} … … 20 25 \end{description} 21 26 22 For all benchmarks, @taskset@ is used to limit the experiment to 1 NUMA Node with no hyper threading. 23 If more \glspl{hthrd} are needed, then 1 NUMA Node with hyperthreading is used. 24 If still more \glspl{hthrd} are needed, then the experiment is limited to as few NUMA Nodes as needed. 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. 25 36 26 37 The limited sharing of the last-level cache on the AMD machine is markedly different than the Intel machine. 27 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 still incur high latency. 28 29 30 \section{Cycling latency} 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 31 68 \begin{figure} 32

Since these two operation also describe a @yield@ operation, many systems use this operation as the most basic benchmark. 39 However, 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. 40 Not all systems perform this type of optimization, but those that do have an artificial performance benefit because the yield becomes a \emph{nop}. 41 For this reason, I chose a different first benchmark, called \newterm{Cycle Benchmark}. 42 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. 43 At runtime, each \at unparks the next \at before parking itself. 44 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. 45 46 Hence, the underlying runtime cannot rely on the number of ready \ats staying constant over the duration of the experiment. 47 In 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. 48 That is, the runtime cannot anticipate that the current task will immediately park. 49 As well, the size of the cycle is also decided based on this delay. 50 Note that, an unpark is like a V on a semaphore, so the subsequent park (P) may not block. 51 If this happens, the scheduler push and pop are avoided and the results of the experiment would be skewed. 52 Because 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. 53 Every runtime system must handle this race and but cannot optimized away the ready-queue pushes and pops if the cycle is long enough. 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. 54 82 To 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. 55 83 Finally, to further mitigate any underlying push/pop optimizations, especially on SMP machines, multiple rings are created in the experiment. 56 84 57 Figure~\ref{fig:cycle:code} shows the pseudo code for this benchmark .85 Figure~\ref{fig:cycle:code} shows the pseudo code for this benchmark, where each cycle has 5 \ats. 58 86 There 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. 59 87 … … 73 101 \caption[Cycle Benchmark : Pseudo Code]{Cycle Benchmark : Pseudo Code} 74 102

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. 144 145 The 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. 146 Each series also has a solid and two dashed lines highlighting the median, maximum and minimum result respectively. 147 This presentation offers an overview of the distribution of the results for each series. 148 149 The experimental setup uses taskset to limit the placement of \glspl{kthrd} by the operating system. 150 As mentioned in Section~\ref{microenv}, the experiement is setup to prioritize running on 2 \glspl{hthrd} per core before running on multiple sockets. 151 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 but \emph{with} hyperthreading. 152 This pattern is repeated between 49 and 96, between 97 and 144, and between 145 and 192. 153 On AMD, the same algorithm is used, but the machine only has 2 sockets. 154 So 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. 155 156 Figure~\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. 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. 157 173 Libfibre is slightly behind in this case but still scales decently. 158 As a result of the \gls{kthrd} placement, we can see that additional \procs from 25 to 48 offer less performance improvements for all runtimes. 159 As expected, this pattern repeats between \proc count 72 and 96. 160 The performance goal of \CFA is to obtain equivalent performance to other, less fair schedulers and that is what results show. 161 Figure~\ref{fig:cycle:jax:ops} and \ref{fig:cycle:jax:ns} show very good throughput and scalability for all runtimes. 162 163 When 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. 165 While \CFA, Go and tokio achive equivalent performance with 100 cycles per \proc, with only 1 cycle per \proc Go achieves slightly better performance. 166 This difference in throughput and scalability is due to the idle-sleep mechanism. 167 With very few cycles, stealing or helping can cause a cascade of tasks migration and trick \proc into very short idle sleeps. 168 Both effect will negatively affect performance. 169 170 An interesting and unusual result is that libfibre achieves better performance with fewer cycle. 171 This suggest that the cascade effect is never present in libfibre and that some bottleneck disappears in this context. 172 However, I did not investigate this result any deeper. 173 174 Figure~\ref{fig:cycle:nasus} show a similar story happening on AMD as it does on Intel. 175 The 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. 176 Unlike Intel, on AMD all 4 runtimes achieve very similar throughput and scalability for 100 cycles per \proc. 177 178 In the 1 cycle per \proc experiment, the same performance increase for libfibre is visible. 179 However, unlike on Intel, tokio achieves the same performance as Go rather than \CFA. 180 This leaves \CFA trailing behind in this particular case, but only at hight core counts. 181 Presumably 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. 182 Since this effect is only problematic in cases with 1 \at per \proc it is not very meaningful for the general performance. 183 184 The conclusion from both architectures is that all of the compared runtime have fairly equivalent performance in this scenario. 185 Which demonstrate that in this case \CFA achieves equivalent performance. 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. 186 197 187 198 \section{Yield} 199 188 200 For completion, the classic yield benchmark is included. 189 This benchmark is simpler than the cycle test: it creates many \ats that call @yield@. 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@. 190 203 As mentioned, this benchmark may not be representative because of optimization shortcuts in @yield@. 191 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. 192 This scenario can put a strain on the idle-sleep handling compared to scenarios where there is plenty of work. 193 Figure~\ref{fig:yield:code} shows pseudo code for this benchmark, where the @wait/next.wake@ is replaced by @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. 194 205 195 206 \begin{figure} … … 207 218 \caption[Yield Benchmark :

the throughput as a function of \proc count on Intel. 272 It is fairly obvious why I claim this benchmark is more artificial. 273 The 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. 275 As a result achieves better performance than the cycle benchmark, but still comparable. 276 277 When the number of \ats is reduce to 1 per \proc, the cost of idle sleep also comes into play in a very significant way. 278 If 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. 279 In the process, several \procs can go to sleep transiently if they fail to find where the \ats were shuffled to. 280 In \CFA, spurious bursts of latency can trick a \proc into helping, triggering this effect. 281 However, 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. 282 283 Libfibre 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. 284 Additionally, when only running 1 \at per \proc, libfibre optimizes further and forgoes the context-switch entirely. 285 This results in incredible performance results comparing to the other runtimes. 286 287 In stark contrast with libfibre, Go puts yielding goroutines on a secondary global ready-queue, giving them lower priority. 288 The result is that multiple \glspl{hthrd} contend for the global queue and performance suffers drastically. 289 Based on the scalability, Tokio obtains the similarly poor performance and therefore it is likely it handles @yield@ in a similar fashion. 290 However, it must be doing something different since it does scale at low \proc count. 291 292 Again, 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. 294 295 Since \CFA obtains the same satisfactory performance as the previous benchmark this is still a success, albeit a less meaningful one. 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. 296 313 297 314 298 315 \section{Churn} 316 299 317 The Cycle and Yield benchmark represent an \emph{easy} scenario for a scheduler, \eg an embarrassingly parallel application. 300 318 In these benchmarks, \ats can be easily partitioned over the different \procs upfront and none of the \ats communicate with each other. 301 319 302 The 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. 303 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 place it on a remote queue. 304 This enqueuing results in either contention on the remote queue and/or \glspl{rmr} on the \at data structure. 305 In 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. 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. 306 325 307 326 This benchmark uses a fixed-size array of counting semaphores. 308 Each \at picks a random semaphore, @V@s it to unblock any \at waiting, and then @P@s on the semaphore.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. 309 328 This creates a flow where \ats push each other out of the semaphores before being pushed out themselves. 310 For this benchmark to work, the number of \ats must be equal or greater than the number of semaphores plus the number of \procs. 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. 311 331 Note, the nature of these semaphores mean the counter can go beyond 1, which can lead to nonblocking calls to @P@. 312 332 Figure~\ref{fig:churn:code} shows pseudo code for this benchmark, where the @yield@ is replaced by @V@ and @P@. … … 328 348 \caption[Churn Benchmark : Pseudo Code]{Churn Benchmark : Pseudo Code} 329 349 \label{fig:churn:code} 350 %\end{figure} 351 \bigskip 352 %\begin{figure} 353

r4fee301 r0c40bfe 50 50 It can therefore be desirable for schedulers to support \ats with identical priorities and/or automatically setting and adjusting priorities for \ats. 51 51 Most common operating systems use some variant on priorities with overlaps and dynamic priority adjustments. 52 For example, Microsoft Windows uses a pair of priorities 53 \cite{win:priority}, one specified by users out of ten possible options and one adjusted by the system. 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. 54 53 55 54 \subsection{Uninformed and Self-Informed Dynamic Schedulers} … … 137 136 The scheduler may also temporarily adjust priorities after certain effects like the completion of I/O requests. 138 137 139 In~\cite{russinovich2009windows}, Chapter 1 section ``Processes, Threads, and Jobs'' discusses the scheduling policy more in depth.140 Multicore scheduling is based on a combination of priorities ,preferred \proc.141 Each \at is assigned an \newterm{ideal} \proc using a round-robin policy.142 \Gls {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.143 This is similar to a variation of work stealing, where the stealing \proc restore the \at to its original \proc after running it, but with priorities added onto the mix.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. 144 143 145 144 \paragraph{Apple OS X} … … 203 202 204 203 \paragraph{Grand Central Dispatch} 205 An Apple \cite{apple:gcd} API that offers task parallelism~\cite{wiki:taskparallel}.204 An Apple~\cite{apple:gcd} API that offers task parallelism~\cite{wiki:taskparallel}. 206 205 Its distinctive aspect is multiple ``Dispatch Queues'', some of which are created by programmers. 207 206 Each queue has its own local ordering guarantees, \eg \ats on queue $A$ are executed in \emph{FIFO} order. 208 207 209 While the documentation only gives limited insight into the scheduling and load balancing approach, \cite{apple:gcd2} suggests an approach fairly classic; 210 Where each \proc has a queue of \newterm{blocks} to run, effectively \ats, and they drain their respective queues in \glsxtrshort{fifo}. 211 They seem to add the concept of dependent queues with clear ordering, where a executing a block ends-up scheduling more blocks. 212 In terms of semantics, these Dispatch Queues seem to be very similar to Intel\textregistered ~TBB @execute()@ and predecessor semantics. 208 While the documentation only gives limited insight into the scheduling and load balancing approach, \cite{apple:gcd2} suggests a fairly classic approach. 209 Each \proc has a queue of \ats to run, called \newterm{blocks}, which are drained in \glsxtrshort{fifo}. 210 \todo{update: They seem to add the concept of dependent queues with clear ordering, where executing a block ends-up scheduling more blocks. 211 In terms of semantics, these Dispatch Queues seem to be very similar to Intel\textregistered ~TBB \lstinline{execute()} and predecessor semantics.} 212 213 213 214 214 \paragraph{LibFibre} -

r4fee301 r0c40bfe 141 141 In the worst case, where all \glspl{thrd} are consistently blocking on \io, it devolves into 1-to-1 threading. 142 142 However, 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.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. 144 144 This advantage is especially relevant for languages like Go, which offer a homogeneous \glsxtrshort{api} across all platforms. 145 145 As opposed to C, which has a very limited standard api for \io, \eg, the C standard library has no networking. … … 151 151 152 152 For this project, I selected @io_uring@, in large parts because of its generality. 153 While @epoll@ has been shown to be a good solution for socket \io (\cite{ DBLP:journals/pomacs/KarstenB20}), @io_uring@'s transparent support for files, pipes, and more complex operations, like @splice@ and @tee@, make it a better choice as the foundation for a general \io subsystem.153 While @epoll@ has been shown to be a good solution for socket \io (\cite{Karsten20}), @io_uring@'s transparent support for files, pipes, and more complex operations, like @splice@ and @tee@, make it a better choice as the foundation for a general \io subsystem. 154 154 155 155 \section{Event-Engine} -
