    77\section{Threading Model}\label{s:threading}
    88\CFA provides user-level threading and supports an $M$:$N$ threading model where $M$ user threads are scheduled on $N$ kernel threads, where both $M$ and $N$ can be explicitly set by the user.
    9 Kernel threads are created by declaring a @processor@ structure.
     9Kernel threads are created by instancing a @processor@ structure.
    1010User-thread types are defined by creating a @thread@ aggregate-type, \ie replace @struct@ with @thread@.
    1111For each thread type a corresponding @main@ routine must be defined, which is where the thread starts running once it is created.
    … …  
    3030When processors are added, they are added alongside the existing processor given to each program.
    3131Thus, for $N$ processors, allocate $N-1$ processors.
    32 A thread is implicitly joined at deallocation, either implicitly at block exit for stack allocation or explicitly at @delete@ for heap allocation.
     32A thread is implicitly joined at deallocated, either implicitly at block exit for stack allocation or explicitly at @delete@ for heap allocation.
    3333The thread performing the deallocation must wait for the thread to terminate before the deallocation can occur.
    3434A thread terminates by returning from the main routine where it starts.

    77\section{Overview}
    8 The following serves as an introduction to \CFA.
    9 \CFA is a layer over C, is transpiled\footnote{Source to source translator.} to C, and is largely considered to be an extension of C.
    10 Beyond C, it adds productivity features, extended libraries, an advanced type-system, and many control-flow/concurrency constructions.
    11 However, \CFA stays true to the C programming style, with most code revolving around @struct@'s and routines, and respects the same rules as C.
    12 \CFA is not object oriented as it has no notion of @this@ (receiver) and no structures with methods, but supports some object oriented ideas including constructors, destructors, and limited nominal inheritance.

    1515\section{References}
    16 References in \CFA are similar to references in \CC; however \CFA references are \emph{rebindable}, and support multi-level referencing.
    17 References in \CFA are a layer of syntactic sugar over pointers to reduce the number of ref/deref operations needed with pointer usage.

     17References in \CFA are a layer of syntactic sugar over pointers to reduce the number of ref/deref operations needed with pointer usage. 
    1818Another difference is the use of @0p@ instead of C's @NULL@ or \CC's @nullptr@.

     62\section{With Statement}
    6363The \CFA @with@ statement is for exposing fields of an aggregate type within a scope, allowing field names without qualification.
    64 This feature is also implemented in Pascal~\cite{Pascal}.
    65 It can exist as a stand-alone statement or wrap a routine body to expose aggregate fields.

    129129C supports limited polymorphism, often requiring users to implement polymorphism using a @void *@ (type erasure) approach.
    130 \CFA extends C with generalized overloading polymorphism (see \VRef{s:Overloading}), as well as, parametric polymorphism and limited nominal inheritance.

    132132\subsection{Parametric Polymorphism}
    133 \CFA provides parametric polymorphism in the form of @forall@, and @trait@s.
    134 A @forall@ takes in a set of types and a list of constraints.
    135 The declarations that follow the @forall@ are parameterized over the types listed that satisfy the constraints.
    136 A list of @forall@ constraints can be refactored into a named @trait@ and reused in @forall@s.

    182 Inheritance in \CFA is taken from Plan-9 C's nominal inheritance.
    183 In \CFA, @struct@s can @inline@ another struct type to gain its fields and masquerade as that type.
    184 Examples of \CFA nominal inheritance are shown in \VRef[Listing]{l:cfa_inherit}.

     7Channels are a concurrent-language feature used to perform \Newterm{message-passing concurrency}: a model of concurrency where threads communicate by sending (mostly nonblocking) data as messages and synchronizing by receiving (blocking) sent data.
     8This model is an alternative to shared-memory concurrency, where threads can communicate directly by changing shared state.
    79Most modern concurrent programming languages do not subscribe to just one style of communication among threads and provide features that support multiple approaches.

    1111Channels were first introduced by Kahn~\cite{Kahn74} and extended by Hoare~\cite{Hoare78} (CSP).
    … …  
    1313Both languages are highly restrictive.
    1414Kahn's language restricts a reading process to only wait for data on a single channel at a time and different writing processes cannot send data on the same channel.
    15 Hoare's language restricts both the sender and receiver to explicitly name the process that is the destination of a channel send or the source of a channel receive.
    16 These channel semantics remove the ability to have an anonymous sender or receiver.
    17 Additionally all channel operations in CSP are synchronous (no buffering).
    18 Advanced channels as a programming language feature has been popularized in recent years by the language Go~\cite{Go}, which encourages the use of channels as its fundamental concurrent feature.
    19 It was the popularity of Go channels that lead to their implemention in \CFA.
    20 Neither Go nor \CFA channels have the restrictions of the early channel-based concurrent systems.

    2220\section{Producer-Consumer Problem}
    23 A channel is an abstraction for a shared-memory buffer, which turns the implementation of a channel into the producer-consumer problem.
    24 The producer-consumer problem, also known as the bounded-buffer problem, was introduced by Dijkstra~\cite[\S~4.1]{Dijkstra65}.
    25 In the problem, threads interact with a buffer in two ways: producing threads insert values into the buffer and consuming threads remove values from the buffer.
    26 In general, a buffer needs protection to ensure a producer only inserts into a non-full buffer and a consumer only removes from a non-empty buffer (synchronization).
    27 As well, a buffer needs protection from concurrent access by multiple producers or consumers attempting to insert or remove simultaneously (MX).
    28 
    29 \section{Channel Size}\label{s:ChannelSize}
    30 Channels come in three flavours of buffers:
    31 \begin{enumerate}
    32 \item
    33 Zero sized implies the communication is synchronous, \ie the producer must wait for the consumer to arrive or vice versa for a value to be communicated.
    34 \item
    35 Fixed sized (bounded) implies the communication is asynchronous, \ie the producer can proceed up to the buffer size and vice versa for the consumer with respect to removal.
    36 \item
    37 Infinite sized (unbounded) implies the communication is asynchronous, \ie the producer never waits but the consumer waits when the buffer is empty.
    38 Since memory is finite, all unbounded buffers are ultimately bounded;
    39 this restriction must be part of its implementation.
    40 \end{enumerate}
    41 
    42 In general, the order values are processed by the consumer does not affect the correctness of the producer-consumer problem.
    43 For example, the buffer can be LIFO, FIFO, or prioritized with respect to insertion and removal.
    44 However, like MX, a buffer should ensure every value is eventually removed after some reasonable bounded time (no long-term starvation).
    45 The simplest way to prevent starvation is to implement the buffer as a queue, either with a cyclic array or linked nodes.
     21Most channels in modern programming languages are built on top of a shared memory buffer.
     22While it is possible to create a channel that contains an unbounded buffer, most implementations opt to only support a fixed size channel, where the size is given at the time of channel creation.
     23This turns the implementation of a channel into the producer-consumer problem.
     24The producer-consumer problem, also known as the bounded buffer problem, was introduced by Dijkstra in his book Cooperating Sequential Processes\cite{Dijkstra65}.
     25In the problem threads interact with the buffer in two ways, either consuming values by removing them from the buffer, or producing values and inserting them in the buffer.
     26The buffer needs to be protected from concurrent access since each item in the buffer should only be produced and consumed once.
     27Additionally, a consumer can only remove from a non-empty buffer and a producer can only insert into a non-full buffer.
    4628
    4729\section{First-Come First-Served}
    48 As pointed out, a bounded buffer requires MX among multiple producers or consumers.
    49 This MX should be fair among threads, independent of the FIFO buffer being fair among values.
    50 Fairness among threads is called \gls{fcfs} and was defined by Lamport~\cite[p.~454]{Lamport74}.
     30The channel implementations that will be discussed are \gls{fcfs}.
     31This term was defined by Lamport~\cite{Lamport74}.
    5132\gls{fcfs} is defined in relation to a doorway~\cite[p.~330]{Lamport86II}, which is the point at which an ordering among threads can be established.
    52 Given this doorway, a CS is said to be \gls{fcfs}, if threads access the shared resource in the order they proceed through the doorway.
    53 A consequence of \gls{fcfs} execution is the elimination of \Newterm{barging}, where barging means a thread arrives at a CS with waiting threads, and the MX protecting the CS allows the arriving thread to enter the CS ahead of one or more of the waiting threads.
    54 
    55 \gls{fcfs} is a fairness property that prevents unequal access to the shared resource and prevents starvation, however it comes at a cost.
    56 Implementing an algorithm with \gls{fcfs} can lead to \Newterm{double blocking}, where arriving threads block outside the doorway waiting for a thread in the lock entry-protocol and inside the doorway waiting for a thread in the CS.
    57 An analogue is boarding an airplane: first you wait to get through security to the departure gates (short term), and then wait again at the departure gate for the airplane (long term).
    58 As such, algorithms that are not \gls{fcfs} (barging) can be more performant by skipping the wait for the CS and entering directly;
    59 however, this performance gain comes by introducing unfairness with possible starvation for waiting threads.
     33Given this doorway, a critical section is said to be \gls{fcfs}, if threads access the shared resource in the order they proceed through the doorway.
     34\gls{fcfs} is a fairness property which prevents unequal access to the shared resource and prevents starvation, however it can come at a cost.
     35Implementing an algorithm with \gls{fcfs} can lead to double blocking, where entering threads may need to block to allow other threads to proceed first, resulting in blocking both inside and outside the doorway.
     36As such algorithms that are not \gls{fcfs} may be more performant but that performance comes with the downside of likely introducing starvation and unfairness.

    6138\section{Channel Implementation}
    62 Currently, only the Go programming language provides user-level threading where the primary communication mechanism is channels.
    63 Experiments were conducted that varied the producer-consumer problem algorithm and lock type used inside the channel.
    64 With the exception of non-\gls{fcfs} or non-FIFO algorithms, no algorithm or lock usage in the channel implementation was found to be consistently more performant that Go's choice of algorithm and lock implementation.
    65 Performance of channels can be improved by sharding the underlying buffer \cite{Dice11}.
    66 In doing so the FIFO property is lost, which is undesireable for user-facing channels.
    67 Therefore, the low-level channel implementation in \CFA is largely copied from the Go implementation, but adapted to the \CFA type and runtime systems.
     39The channel implementation in \CFA is a near carbon copy of the Go implementation.
     40Experimentation was conducted that varied the producer-consumer problem algorithm and lock type used inside the channel.
     41With the exception of non-\gls{fcfs} algorithms, no algorithm or lock usage in the channel implementation was found to be consistently more performant that Go's choice of algorithm and lock implementation.
    6842As such the research contributions added by \CFA's channel implementation lie in the realm of safety and productivity features.
    69 
    70 The Go channel implementation utilitizes cooperation between threads to achieve good performance~\cite{go:chan}.
    71 The cooperation between threads only occurs when producers or consumers need to block due to the buffer being full or empty.
    72 In these cases the blocking thread stores their relevant data in a shared location and the signalling thread will complete their operation before waking them.
    73 This helps improve performance in a few ways.
    74 First, each thread interacting with the channel with only acquire and release the internal channel lock exactly once.
    75 This decreases contention on the internal lock, as only entering threads will compete for the lock since signalled threads never reacquire the lock.
    76 The other advantage of the cooperation approach is that it eliminates the potential bottleneck of waiting for signalled threads.
    77 The property of acquiring/releasing the lock only once can be achieved without cooperation by \Newterm{baton passing} the lock.
    78 Baton passing is when one thread acquires a lock but does not release it, and instead signals a thread inside the critical section conceptually "passing" the mutual exclusion to the signalled thread.
    79 While baton passing is useful in some algorithms, it results in worse performance than the cooperation approach in channel implementations since all entering threads then need to wait for the blocked thread to reach the front of the ready queue and run before other operations on the channel can proceed.
    80 
    81 In this work, all channel sizes \see{Sections~\ref{s:ChannelSize}} are implemented with bounded buffers.
    82 However, only non-zero-sized buffers are analysed because of their complexity and higher usage.

    … …

    8848\begin{itemize}
    89 \item Toggle-able statistic collection on channel behaviour that count channel and blocking operations.
    90 Tracking blocking operations helps illustrate usage for tuning the channel size, where the aim is to reduce blocking.
    91 
    92 \item Deadlock detection on channel deallocation.
    93 If threads are blocked inside a channel when it terminates, this case is detected and the user is informed, as this can cause a deadlock.
    94 
    95 \item A @flush@ routine that delivers copies of an element to all waiting consumers, flushing the buffer.
    96 Programmers use this mechanism to broadcast a sentinel value to multiple consumers.
    97 Additionally, the @flush@ routine is more performant then looping around the @insert@ operation since it can deliver the elements without having to reacquire mutual exclusion for each element sent.
     49\item Toggle-able statistic collection on channel behaviour that counts channel operations, and the number of the operations that block.
     50Tracking blocking operations helps users tune their channel size or channel usage when the channel is used for buffering, where the aim is to have as few blocking operations as possible.
     51\item Deadlock detection on deallocation of the channel.
     52If any threads are blocked inside the channel when it terminates it is detected and informs the user, as this would cause a deadlock.
     53\item A \code{flush} routine that delivers copies of an element to all waiting consumers, flushing the buffer.
     54Programmers can use this to easily to broadcast data to multiple consumers.
     55Additionally, the \code{flush} routine is more performant then looping around the \code{insert} operation since it can deliver the elements without having to reacquire mutual exclusion for each element sent.
    9856\end{itemize}

    100 \subsection{Toggle-able Statistics}
    101 As discussed, a channel is a concurrent layer over a bounded buffer.
    102 To achieve efficient buffering users should aim for as few blocking operations on a channel as possible.
    103 Often to achieve this users may change the buffer size, shard a channel into multiple channels, or tweak the number of producer and consumer threads.
    104 Fo users to be able to make informed decisions when tuning channel usage, toggle-able channel statistics are provided.
    105 The statistics are toggled at compile time via the @CHAN_STATS@ macro to ensure that they are entirely elided when not used.
    106 When statistics are turned on, four counters are maintained per channel, two for producers and two for consumers.
    107 The two counters per type of operation track the number of blocking operations and total operations.
    108 In the channel destructor the counters are printed out aggregated and also per type of operation.
    109 An example use case of the counters follows.
    110 A user is buffering information between producer and consumer threads and wants to analyze channel performance.
    111 Via the statistics they see that producers block for a large percentage of their operations while consumers do not block often.
    112 They then can use this information to adjust their number of producers/consumers or channel size to achieve a larger percentage of non-blocking producer operations, thus increasing their channel throughput.
    113 
    114 \subsection{Deadlock Detection}
    115 The deadlock detection in the \CFA channels is fairly basic.
    116 It only detects the case where threads are blocked on the channel during deallocation.
    117 This case is guaranteed to deadlock since the list holding the blocked thread is internal to the channel and will be deallocated.
    118 If a user maintained a separate reference to a thread and unparked it outside the channel they could avoid the deadlock, but would run into other runtime errors since the thread would access channel data after waking that is now deallocated.
    119 More robust deadlock detection surrounding channel usage would have to be implemented separate from the channel implementation since it would require knowledge about the threading system and other channel/thread state.
    120 
    121 \subsection{Program Shutdown}
     58The other safety and productivity feature of \CFA channels deals with concurrent termination.
    12259Terminating concurrent programs is often one of the most difficult parts of writing concurrent code, particularly if graceful termination is needed.
    123 The difficulty of graceful termination often arises from the usage of synchronization primitives that need to be handled carefully during shutdown.
     60The difficulty of graceful termination often arises from the usage of synchronization primitives which need to be handled carefully during shutdown.
    12461It is easy to deadlock during termination if threads are left behind on synchronization primitives.
    12562Additionally, most synchronization primitives are prone to \gls{toctou} issues where there is race between one thread checking the state of a concurrent object and another thread changing the state.
    12663\gls{toctou} issues with synchronization primitives often involve a race between one thread checking the primitive for blocked threads and another thread blocking on it.
    127 Channels are a particularly hard synchronization primitive to terminate since both sending and receiving to/from a channel can block.
     64Channels are a particularly hard synchronization primitive to terminate since both sending and receiving off a channel can block.
    12865Thus, improperly handled \gls{toctou} issues with channels often result in deadlocks as threads trying to perform the termination may end up unexpectedly blocking in their attempt to help other threads exit the system.
    12966
    130 \paragraph{Go channels} provide a set of tools to help with concurrent shutdown~\cite{go:chan}.
    131 Channels in Go have a @close@ operation and a \Go{select} statement that both can be used to help threads terminate.
    132 The \Go{select} statement is discussed in \ref{s:waituntil}, where \CFA's @waituntil@ statement is compared with the Go \Go{select} statement.
    133 
    134 The @close@ operation on a channel in Go changes the state of the channel.
    135 When a channel is closed, sends to the channel panic along with additional calls to @close@.
    136 Receives are handled differently.
    137 Receivers (consumers) never block on a closed channel and continue to remove elements from the channel.
    138 Once a channel is empty, receivers can continue to remove elements, but receive the zero-value version of the element type.
    139 To avoid unwanted zero-value elements, Go provides the ability to iterate over a closed channel to remove the remaining elements.
    140 These Go design choices enforce a specific interaction style with channels during termination: careful thought is needed to ensure additional @close@ calls do not occur and no sends occur after a channel is closed.
     67% C_TODO: add reference to select chapter, add citation to go channels info
     68Go channels provide a set of tools to help with concurrent shutdown.
     69Channels in Go have a \code{close} operation and a \code{select} statement that both can be used to help threads terminate.
     70The \code{select} statement will be discussed in \ref{}, where \CFA's \code{waituntil} statement will be compared with the Go \code{select} statement.
     71The \code{close} operation on a channel in Go changes the state of the channel.
     72When a channel is closed, sends to the channel will panic and additional calls to \code{close} will panic.
     73Receives are handled differently where receivers will never block on a closed channel and will continue to remove elements from the channel.
     74Once a channel is empty, receivers can continue to remove elements, but will receive the zero-value version of the element type.
     75To aid in avoiding unwanted zero-value elements, Go provides the ability to iterate over a closed channel to remove the remaining elements.
     76These design choices for Go channels enforce a specific interaction style with channels during termination, where careful thought is needed to ensure that additional \code{close} calls don't occur and that no sends occur after channels are closed.
    14177These design choices fit Go's paradigm of error management, where users are expected to explicitly check for errors, rather than letting errors occur and catching them.
    142 If errors need to occur in Go, return codes are used to pass error information up call levels.
    143 Note, panics in Go can be caught, but it is not the idiomatic way to write Go programs.
     78If errors need to occur in Go, return codes are used to pass error information where they are needed.
     79Note that panics in Go can be caught, but it is not considered an idiomatic way to write Go programs.
    14480
    14581While Go's channel closing semantics are powerful enough to perform any concurrent termination needed by a program, their lack of ease of use leaves much to be desired.
    146 Since both closing and sending panic once a channel is closed, a user often has to synchronize the senders (producers) before the channel can be closed to avoid panics.
    147 However, in doing so it renders the @close@ operation nearly useless, as the only utilities it provides are the ability to ensure receivers no longer block on the channel and receive zero-valued elements.
    148 This functionality is only useful if the zero-typed element is recognized as a sentinel value, but if another sentinel value is necessary, then @close@ only provides the non-blocking feature.
    149 To avoid \gls{toctou} issues during shutdown, a busy wait with a \Go{select} statement is often used to add or remove elements from a channel.
     82Since both closing and sending panic, once a channel is closed, a user often has to synchronize the senders to a channel before the channel can be closed to avoid panics.
     83However, in doing so it renders the \code{close} operation nearly useless, as the only utilities it provides are the ability to ensure that receivers no longer block on the channel, and will receive zero-valued elements.
     84This can be useful if the zero-typed element is recognized as a sentinel value, but if another sentinel value is preferred, then \code{close} only provides its non-blocking feature.
     85To avoid \gls{toctou} issues during shutdown, a busy wait with a \code{select} statement is often used to add or remove elements from a channel.
    15086Due to Go's asymmetric approach to channel shutdown, separate synchronization between producers and consumers of a channel has to occur during shutdown.
    15187
    152 \paragraph{\CFA channels} have access to an extensive exception handling mechanism~\cite{Beach21}.
    153 As such \CFA uses an exception-based approach to channel shutdown that is symmetric for both producers and consumers, and supports graceful shutdown.
    154 
    155 Exceptions in \CFA support both termination and resumption.
    156 \Newterm{Termination exception}s perform a dynamic call that unwinds the stack preventing the exception handler from returning to the raise point, such as in \CC, Python and Java.
    157 \Newterm{Resumption exception}s perform a dynamic call that does not unwind the stack allowing the exception handler to return to the raise point.
    158 In \CFA, if a resumption exception is not handled, it is reraised as a termination exception.
    159 This mechanism is used to create a flexible and robust termination system for channels.
    160 
    161 When a channel in \CFA is closed, all subsequent calls to the channel raise a resumption exception at the caller.
    162 If the resumption is handled, the caller attempts to complete the channel operation.
    163 However, if channel operation would block, a termination exception is thrown.
    164 If the resumption is not handled, the exception is rethrown as a termination.
    165 These termination exceptions allow for non-local transfer that is used to great effect to eagerly and gracefully shut down a thread.
     88In \CFA, exception handling is an encouraged paradigm and has full language support \cite{Beach21}.
     89As such \CFA uses an exception based approach to channel shutdown that is symmetric for both producers and consumers, and supports graceful shutdown.Exceptions in \CFA support both termination and resumption.Termination exceptions operate in the same way as exceptions seen in many popular programming languages such as \CC, Python and Java.
     90Resumption exceptions are a style of exception that when caught run the corresponding catch block in the same way that termination exceptions do.
     91The difference between the exception handling mechanisms arises after the exception is handled.
     92In termination handling, the control flow continues into the code following the catch after the exception is handled.
     93In resumption handling, the control flow returns to the site of the \code{throw}, allowing the control to continue where it left off.
     94Note that in resumption, since control can return to the point of error propagation, the stack is not unwound during resumption propagation.
     95In \CFA if a resumption is not handled, it is reraised as a termination.
     96This mechanism can be used to create a flexible and robust termination system for channels.
     97
     98When a channel in \CFA is closed, all subsequent calls to the channel will throw a resumption exception at the caller.
     99If the resumption is handled, then the caller will proceed to attempt to complete their operation.
     100If the resumption is not handled it is then rethrown as a termination exception.
     101Or, if the resumption is handled, but the subsequent attempt at an operation would block, a termination exception is thrown.
     102These termination exceptions allow for non-local transfer that can be used to great effect to eagerly and gracefully shut down a thread.
    166103When a channel is closed, if there are any blocked producers or consumers inside the channel, they are woken up and also have a resumption thrown at them.
    167 The resumption exception, @channel_closed@, has a couple fields to aid in handling the exception.
     104The resumption exception, \code{channel_closed}, has a couple fields to aid in handling the exception.
    168105The exception contains a pointer to the channel it was thrown from, and a pointer to an element.
    169106In exceptions thrown from remove the element pointer will be null.
    … …  
    175112This should not be an issue, since termination is rarely an fast-path of an application and ensuring that termination can be implemented correctly with ease is the aim of the exception approach.
    176113
    177 \section{\CFA / Go channel Examples}
    178 To highlight the differences between \CFA's and Go's close semantics, three examples will be presented.
    179 The first example is a simple shutdown case, where there are producer threads and consumer threads operating on a channel for a fixed duration.
    180 Once the duration ends, producers and consumers terminate without worrying about any leftover values in the channel.
    181 The second example extends the first example by requiring the channel to be empty upon shutdown.
    182 Both the first and second example are shown in Figure~\ref{f:ChannelTermination}.
    183 
    184 
    185 First the Go solutions to these examples shown in Figure~\ref{l:go_chan_term} are discussed.
    186 Since some of the elements being passed through the channel are zero-valued, closing the channel in Go does not aid in communicating shutdown.
    187 Instead, a different mechanism to communicate with the consumers and producers needs to be used.
     114To highlight the differences between \CFA's and Go's close semantics, an example program is presented.
     115The program is a barrier implemented using two channels shown in Listings~\ref{l:cfa_chan_bar} and \ref{l:go_chan_bar}.
     116Both of these examples are implemented using \CFA syntax so that they can be easily compared.
     117Listing~\ref{l:go_chan_bar} uses go-style channel close semantics and Listing~\ref{l:cfa_chan_bar} uses \CFA close semantics.
     118In this problem it is infeasible to use the Go \code{close} call since all tasks are both potentially producers and consumers, causing panics on close to be unavoidable.
     119As such in Listing~\ref{l:go_chan_bar} to implement a flush routine for the buffer, a sentinel value of $-1$ has to be used to indicate to threads that they need to leave the barrier.
     120This sentinel value has to be checked at two points.
     121Furthermore, an additional flag \code{done} is needed to communicate to threads once they have left the barrier that they are done.
    188122This use of an additional flag or communication method is common in Go channel shutdown code, since to avoid panics on a channel, the shutdown of a channel often has to be communicated with threads before it occurs.
    189 In this example, a flag is used to communicate with producers and another flag is used for consumers.
    190 Producers and consumers need separate avenues of communication both so that producers terminate before the channel is closed to avoid panicking, and to avoid the case where all the consumers terminate first, which can result in a deadlock for producers if the channel is full.
    191 The producer flag is set first, then after producers terminate the consumer flag is set and the channel is closed.
    192 In the second example where all values need to be consumed, the main thread iterates over the closed channel to process any remaining values.
    193 
    194 
    195 In the \CFA solutions in Figure~\ref{l:cfa_chan_term}, shutdown is communicated directly to both producers and consumers via the @close@ call.
    196 In the first example where all values do not need to be consumed, both producers and consumers do not handle the resumption and finish once they receive the termination exception.
    197 The second \CFA example where all values must be consumed highlights how resumption is used with channel shutdown.
    198 The @Producer@ thread-main knows to stop producing when the @insert@ call on a closed channel raises exception @channel_closed@.
    199 The @Consumer@ thread-main knows to stop consuming after all elements of a closed channel are removed and the call to @remove@ would block.
    200 Hence, the consumer knows the moment the channel closes because a resumption exception is raised, caught, and ignored, and then control returns to @remove@ to return another item from the buffer.
    201 Only when the buffer is drained and the call to @remove@ would block, a termination exception is raised to stop consuming.
    202 The \CFA semantics allow users to communicate channel shutdown directly through the channel, without having to share extra state between threads.
    203 Additionally, when the channel needs to be drained, \CFA provides users with easy options for processing the leftover channel values in the main thread or in the consumer threads.
    204 If one wishes to consume the leftover values in the consumer threads in Go, extra synchronization between the main thread and the consumer threads is needed.

    303 The final shutdown example uses channels to implement a barrier.
    304 It is shown in Figure~\ref{f:ChannelBarrierTermination}.
    305 The problem of implementing a barrier is chosen since threads are both producers and consumers on the barrier-internal channels, which removes the ability to easily synchronize producers before consumers during shutdown.
    306 As such, while the shutdown details will be discussed with this problem in mind, they are also applicable to other problems taht have individual threads both producing and consuming from channels.
    307 Both of these examples are implemented using \CFA syntax so that they can be easily compared.
    308 Figure~\ref{l:cfa_chan_bar} uses \CFA-style channel close semantics and Figure~\ref{l:go_chan_bar} uses Go-style close semantics.
    309 In this example it is infeasible to use the Go @close@ call since all threads are both potentially producers and consumers, causing panics on close to be unavoidable without complex synchronization.
    310 As such in Figure~\ref{l:go_chan_bar} to implement a flush routine for the buffer, a sentinel value of @-1@ has to be used to indicate to threads that they need to leave the barrier.
    311 This sentinel value has to be checked at two points.
    312 Furthermore, an additional flag @done@ is needed to communicate to threads once they have left the barrier that they are done.
    313 
    314123In the \CFA version~\ref{l:cfa_chan_bar}, the barrier shutdown results in an exception being thrown at threads operating on it, which informs the threads that they must terminate.
    315124This avoids the need to use a separate communication method other than the barrier, and avoids extra conditional checks on the fast path of the barrier implementation.
    316125Also note that in the Go version~\ref{l:go_chan_bar}, the size of the barrier channels has to be larger than in the \CFA version to ensure that the main thread does not block when attempting to clear the barrier.

     248In Listing~\ref{l:cfa_resume} an example of channel closing with resumption is used.
     249This program uses resumption in the \code{Consumer} thread main to ensure that all elements in the channel are removed before the consumer thread terminates.
     250The producer only has a \code{catch} so the moment it receives an exception it terminates, whereas the consumer will continue to remove from the closed channel via handling resumptions until the buffer is empty, which then throws a termination exception.
     251If the same program was implemented in Go it would require explicit synchronization with both producers and consumers by some mechanism outside the channel to ensure that all elements were removed before task termination.

    430 Given that the base implementation of the \CFA channels is very similar to the Go implementation, this section aims to show the performance of the two implementations are comparable.
    431 The microbenchmark for the channel comparison is similar to Figure~\ref{f:ChannelTermination}, where the number of threads and processors is set from the command line.
    432 The processors are divided equally between producers and consumers, with one producer or consumer owning each core.
     293Given that the base implementation of the \CFA channels is very similar to the Go implementation, this section aims to show that the performance of the two implementations are comparable.
     294One microbenchmark is conducted to compare Go and \CFA.
     295The benchmark is a ten second experiment where producers and consumers operate on a channel in parallel and throughput is measured.
    433296The number of cores is varied to measure how throughput scales.

     297The cores are divided equally between producers and consumers, with one producer or consumer owning each core.
    435298The results of the benchmark are shown in Figure~\ref{f:chanPerf}.
    436299The performance of Go and \CFA channels on this microbenchmark is comparable.
    437 Note, the performance should decline as the number of cores increases as the channel operations occur in a critical section, so increasing cores results in higher contention with no increase in parallelism.
     300Note, it is expected for the performance to decline as the number of cores increases as the channel operations all occur in a critical section so an increase in cores results in higher contention with no increase in parallelism.

    8080Concurrent programs are notoriously hard to program and even harder to debug. Furthermore concurrent programs must be performant, as the introduction of concurrency into a program is often done to achieve some form of speedup.
    8181
    82 This thesis presents a suite of high-level concurrent-language features in the new programming-language \CFA, all of which are implemented with the aim of improving the performance, productivity, and safety of concurrent programs.
    83 \CFA is a non-object-oriented programming language that extends C.
    84 The foundation for concurrency in \CFA was laid by Thierry Delisle~\cite{Delisle18}, who implemented coroutines, user-level threads, and monitors.
    85 This thesis builds upon that work and introduces a suite of new concurrent features as its main contribution.
    86 The features include a @mutex@ statement (similar to a \CC scoped lock or Java \lstinline[language=Java]{synchronized} statement), Go-like channels and \lstinline[language=Go]{select} statement, and an actor system.
    87 The root ideas behind these features are not new, but the \CFA implementations extends the original ideas in performance, productivity, and safety.

    88To seize the reins and write performant and safe concurrent code, high-level concurrent-language features are needed.
    99Like any other craftsmen, programmers are only as good as their tools, and concurrent tooling and features are no exception.

    7 The mutual exclusion problem was introduced by Dijkstra in 1965~\cite{Dijkstra65,Dijkstra65a}:
    8 there are several concurrent processes or threads that communicate by shared variables and from time to time need exclusive access to shared resources.
     7The mutual exclusion problem was introduced by Dijkstra in 1965~\cite{Dijkstra65,Dijkstra65a}.
     8There are several concurrent processes or threads that communicate by shared variables and from time to time need exclusive access to shared resources.
    99A shared resource and code manipulating it form a pairing called a \Newterm{critical section (CS)}, which is a many-to-one relationship;
    1010\eg if multiple files are being written to by multiple threads, only the pairings of simultaneous writes to the same files are CSs.

    2727\section{Monitor}
    28 \CFA provides a high-level locking object, called a \Newterm{monitor}, an elegant and efficient abstraction for providing mutual exclusion and synchronization for shared-memory systems.
    29 First proposed by Brinch Hansen~\cite{Hansen73} and later described and extended by C.A.R.~Hoare~\cite{Hoare74}.
    30 Several concurrent programming languages provide monitors as an explicit language construct: \eg Concurrent Pascal~\cite{ConcurrentPascal}, Mesa~\cite{Mesa}, Turing~\cite{Turing:old}, Modula-3~\cite{Modula-3}, \uC~\cite{Buhr92a} and Java~\cite{Java}.

    3130In addition, operating-system kernels and device drivers have a monitor-like structure, although they often use lower-level primitives such as mutex locks or semaphores to manually implement a monitor.
    3231
    3332Figure~\ref{f:AtomicCounter} shows a \CFA and Java monitor implementing an atomic counter.
    3433A \Newterm{monitor} is a programming technique that implicitly binds mutual exclusion to static function scope by call and return.
    35 In contrast, lock mutual exclusion, defined by acquire/release calls, is independent of lexical context (analogous to block versus heap storage allocation).
     34Lock mutual exclusion, defined by acquire/release calls, is independent of lexical context (analogous to block versus heap storage allocation).
    3635Restricting acquire and release points in a monitor eases programming, comprehension, and maintenance, at a slight cost in flexibility and efficiency.
    3736Ultimately, a monitor is implemented using a combination of basic locks and atomic instructions.
    … …  
    111110To increase locking flexibility, some languages introduce a mutex statement.
    112111\VRef[Figure]{f:ReadersWriter} shows the outline of a reader/writer lock written as a \CFA monitor and mutex statements.
    113 (The exact lock implementation is irrelevant.)
     112(The exact lock implement is irrelevant.)
    114113The @read@ and @write@ functions are called with a reader/write lock and any arguments to perform reading or writing.
    115114The @read@ function is not MX because multiple readers can read simultaneously.
    … …  
    272271The @scoped_lock@ uses a deadlock avoidance algorithm where all locks after the first are acquired using @try_lock@ and if any of the lock attempts fail, all acquired locks are released.
    273272This repeats after selecting a new starting point in a cyclic manner until all locks are acquired successfully.
    274 This deadlock avoidance algorithm is shown in Figure~\ref{f:cc_deadlock_avoid}.
     273This deadlock avoidance algorithm is shown in Listing~\ref{l:cc_deadlock_avoid}.
    275274The algorithm is taken directly from the source code of the @<mutex>@ header, with some renaming and comments for clarity.
    276275

     276\begin{cfa}[caption={\CC \lstinline{scoped_lock} deadlock avoidance algorithm},label={l:cc_deadlock_avoid}]

    280278do {

    298 
    299 While this algorithm successfully avoids deadlock, there is a livelock scenario.
     293
     294While the algorithm in \ref{l:cc_deadlock_avoid} successfully avoids deadlock, there is a livelock scenario.
    300295Assume two threads, $A$ and $B$, create a @scoped_lock@ accessing two locks, $L1$ and $L2$.
    301296A livelock can form as follows.
    … …  
    340335\end{cquote}
    341336Comparatively, if the @scoped_lock@ is used and the same locks are acquired elsewhere, there is no concern of the @scoped_lock@ deadlocking, due to its avoidance scheme, but it may livelock.
    342 The convenience and safety of the @mutex@ statement, \eg guaranteed lock release with exceptions, should encourage programmers to always use it for locking, mitigating any deadlock scenario versus combining manual locking with the mutex statement.

    350345
    351346The benchmark used to evaluate the avoidance algorithms repeatedly acquires a fixed number of locks in a random order and then releases them.
    352 The pseudocode for the deadlock avoidance benchmark is shown in \VRef[Listing]{l:deadlock_avoid_pseudo}.
     347The pseudo code for the deadlock avoidance benchmark is shown in \VRef[Listing]{l:deadlock_avoid_pseudo}.
    353348To ensure the comparison exercises the implementation of each lock avoidance algorithm, an identical spinlock is implemented in each language using a set of builtin atomics available in both \CC and \CFA.
    354349The benchmarks are run for a fixed duration of 10 seconds and then terminate.
    … …  
    357352The median is calculated and is plotted alongside the 95\% confidence intervals for each point.

    403375Figure~\ref{f:mutex_bench} shows the results of the benchmark experiments.
     376\PAB{Make the points in the graphs for each line different.
     377Also, make the text in the graphs larger.}
    404378The baseline results for both languages are mostly comparable, except for the 8 locks results in \ref{f:mutex_bench8_AMD} and \ref{f:mutex_bench8_Intel}, where the \CFA baseline is slightly slower.
    405379The avoidance result for both languages is significantly different, where \CFA's mutex statement achieves throughput that is magnitudes higher than \CC's @scoped_lock@.
    … …  
    409383For example, on the AMD machine with 32 threads and 8 locks, the benchmarks would occasionally livelock indefinitely, with no threads making any progress for 3 hours before the experiment was terminated manually.
    410384It is likely that shorter bouts of livelock occurred in many of the experiments, which would explain large confidence intervals for some of the data points in the \CC data.
    411 In Figures~\ref{f:mutex_bench8_AMD} and \ref{f:mutex_bench8_Intel} there is the counter-intuitive result of the mutex statement performing better than the baseline.
    412 At 7 locks and above the mutex statement switches from a hard coded sort to insertion sort, which should decrease performance.
    413 It is likely the increase in throughput compared to baseline is due to the delay spent in the insertion sort, which decreases contention on the locks.
     385In Figures~\ref{f:mutex_bench8_AMD} and \ref{f:mutex_bench8_Intel} the mutex statement performs better than the baseline.
     386At 7 locks and above the mutex statement switches from a hard coded sort to insertion sort.
     387It is likely that the improvement in throughput compared to baseline is due to the time spent in the insertion sort, which decreases contention on the locks.
