    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 instancing a @processor@ structure.
     9Kernel threads are created by declaring 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 deallocated, either implicitly at block exit for stack allocation or explicitly at @delete@ for heap allocation.
     32A thread is implicitly joined at deallocation, 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 containment inheritance.

    1515\section{References}
    16 References in \CFA are similar to references in \CC; however \CFA references are 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@.

    39 \CFA routines can be overloaded on parameter type, number of parameters, and \emph{return type}. 
    40 Variables can also be overloaded on type, meaning that two variables can have the same name so long as they have different types.

     62\section{\lstinline{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 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. 
    137 Examples of \CFA parametric polymorphism are shown in \VRef[Listing]{l:cfa_poly}.

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

    7 Channels 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.
     7Most modern concurrent programming languages do not subscribe to just one style of communication among threads and provide features that support multiple approaches.

    89This model is an alternative to shared-memory concurrency, where threads can communicate directly by changing shared state.

    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 ...
    16 Channels as a programming language feature has been popularized in recent years due to the language Go, which encourages the use of channels as its fundamental concurrent feature.
    17 Go's restrictions are ...
     15Hoare's language restricts channels such that both the sender and receiver need to explicitly name the process that is destination of a channel send or the source of a channel receive.
     16These channel semantics remove the ability to have an anonymous sender or receiver and additionally all channel operations in CSP are synchronous (no buffering).
     17Channels as a programming language feature has been popularized in recent years by the language Go, which encourages the use of channels as its fundamental concurrent feature.
     18Go's restrictions are ... \CAP{The only restrictions in Go but not CFA that I can think of are the closing semantics and the functionality of select vs. waituntil. Is that worth mentioning here or should it be discussed later?}
    1819\CFA channels do not have these restrictions.

    2021\section{Producer-Consumer Problem}
    21 Most channels in modern programming languages are built on top of a shared memory buffer.
    22 While 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.
    23 This 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 in his book Cooperating Sequential Processes\cite{Dijkstra65}.
    25 In 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.
    26 The buffer needs to be protected from concurrent access since each item in the buffer should only be produced and consumed once.
    27 Additionally, a consumer can only remove from a non-empty buffer and a producer can only insert into a non-full buffer.
     22A channel is an abstraction for a shared-memory buffer, which turns the implementation of a channel into the producer-consumer problem.
     23The producer-consumer problem, also known as the bounded-buffer problem, was introduced by Dijkstra~\cite[\S~4.1]{Dijkstra65}.
     24In 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.
     25In 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).
     26As well, a buffer needs protection from concurrent access by multiple producers or consumers attempt to insert or remove simultaneously (MX).
     27
     28Channels come in three flavours of buffers:
     29\begin{enumerate}
     30\item
     31Zero 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.
     32\item
     33Fixed 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.
     34\item
     35Infinite sized (unbounded) implies the communication is asynchronous, \ie the producer never waits but the consumer waits when the buffer is empty.
     36Since memory is finite, all unbounded buffers are ultimately bounded;
     37this restriction must be part of its implementation.
     38\end{enumerate}
     39
     40In general, the order values are processed by the consumer does not affect the correctness of the producer-consumer problem.
     41For example, the buffer can be LIFO, FIFO, or prioritized with respect to insertion and removal.
     42However, like MX, a buffer should ensure every value is eventually removed after some reasonable bounded time (no long-term starvation).
     43The simplest way to prevent starvation is to implement the buffer as a queue, either with a cyclic array or linked nodes.
    2844
    2945\section{First-Come First-Served}
    30 The channel implementations that will be discussed are \gls{fcfs}.
    31 This term was defined by Lamport~\cite{Lamport74}.
     46As pointed out, a bounded buffer requires MX among multiple producers or consumers.
     47This MX should be fair among threads, independent of the FIFO buffer being fair among values.
     48Fairness among threads is called \gls{fcfs} and was defined by Lamport~\cite[p.~454]{Lamport74}.
    3249\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.
    33 Given 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.
    35 Implementing 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.
    36 As such algorithms that are not \gls{fcfs} may be more performant but that performance comes with the downside of likely introducing starvation and unfairness.
     50Given this doorway, a CS is said to be \gls{fcfs}, if threads access the shared resource in the order they proceed through the doorway.
     51A 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.
     52
     53\gls{fcfs} is a fairness property that prevents unequal access to the shared resource and prevents starvation, however it comes at a cost.
     54Implementing an algorithm with \gls{fcfs} can lead to 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.
     55An 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).
     56As such, algorithms that are not \gls{fcfs} (barging) can be more performant by skipping the wait for the CS and entering directly;
     57however, this performance gain comes by introducing unfairness with possible starvation for waiting threads.

    3859\section{Channel Implementation}
    39 The channel implementation in \CFA is a near carbon copy of the Go implementation.
    40 Experimentation was conducted that varied the producer-consumer problem algorithm and lock type used inside the channel.
     60Currently, only the Go programming language~\cite{Go} provides user-level threading where the primary communication mechanism is channels.
     61Experiments were conducted that varied the producer-consumer problem algorithm and lock type used inside the channel.
    4162With 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.
     63Therefore, the low-level channel implementation in \CFA is largely copied from the Go implementation, but adapted to the \CFA type and runtime systems.
    4264As such the research contributions added by \CFA's channel implementation lie in the realm of safety and productivity features.
     65
     66\PAB{Discuss the Go channel implementation. Need to tie in FIFO buffer and FCFS locking.}
     67
     68In this work, all channels are implemented with bounded buffers, so there is no zero-sized buffering.
     69\CAP{I do have zero size channels implemented, however I don't focus on them since I think they are uninteresting as they are just a thin layer over binary semaphores. Should I mention that I support it but omit discussion or just leave it out?}

    49 \item Toggle-able statistic collection on channel behaviour that counts channel operations, and the number of the operations that block.

     76\item Toggle-able statistic collection on channel behaviour that count channel and blocking operations.
     77Tracking blocking operations helps illustrate usage and then tune the channel size, where the aim is to reduce blocking.
    5178\item Deadlock detection on deallocation of the channel.
    52 If 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.
     79If threads are blocked inside the channel when it terminates, this case is detected and the user is informed, as this can cause a deadlock.
     80\item A @flush@ routine that delivers copies of an element to all waiting consumers, flushing the buffer.
    5481Programmers can use this to easily to broadcast data to multiple consumers.
    55 Additionally, 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.

    6895Go channels provide a set of tools to help with concurrent shutdown.
    69 Channels in Go have a \code{close} operation and a \code{select} statement that both can be used to help threads terminate.
    70 The \code{select} statement will be discussed in \ref{}, where \CFA's \code{waituntil} statement will be compared with the Go \code{select} statement.
    71 The \code{close} operation on a channel in Go changes the state of the channel.
    72 When a channel is closed, sends to the channel will panic and additional calls to \code{close} will panic.
     96Channels in Go have a @close@ operation and a \Go{select} statement that both can be used to help threads terminate.
     97The \Go{select} statement will be discussed in \ref{}, where \CFA's @waituntil@ statement will be compared with the Go \Go{select} statement.
     98The @close@ operation on a channel in Go changes the state of the channel.
     99When a channel is closed, sends to the channel will panic and additional calls to @close@ will panic.
    73100Receives are handled differently where receivers will never block on a closed channel and will continue to remove elements from the channel.
    74101Once a channel is empty, receivers can continue to remove elements, but will receive the zero-value version of the element type.
    75102To aid in avoiding unwanted zero-value elements, Go provides the ability to iterate over a closed channel to remove the remaining elements.
    76 These 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.
     103These design choices for Go channels enforce a specific interaction style with channels during termination, where careful thought is needed to ensure that additional @close@ calls don't occur and that no sends occur after channels are closed.
    77104These 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.
    78105If errors need to occur in Go, return codes are used to pass error information where they are needed.
    … …  
    81108While 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.
    82109Since 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.
    83 However, 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.
    84 This 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.
    85 To 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.

     112To 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.
    86113Due to Go's asymmetric approach to channel shutdown, separate synchronization between producers and consumers of a channel has to occur during shutdown.
    87114
    … …  
    91118The difference between the exception handling mechanisms arises after the exception is handled.
    92119In termination handling, the control flow continues into the code following the catch after the exception is handled.
    93 In resumption handling, the control flow returns to the site of the \code{throw}, allowing the control to continue where it left off.
     120In resumption handling, the control flow returns to the site of the @throw@, allowing the control to continue where it left off.
    94121Note that in resumption, since control can return to the point of error propagation, the stack is not unwound during resumption propagation.
    95122In \CFA if a resumption is not handled, it is reraised as a termination.
    … …  
    102129These termination exceptions allow for non-local transfer that can be used to great effect to eagerly and gracefully shut down a thread.
    103130When 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.
    104 The resumption exception, \code{channel_closed}, has a couple fields to aid in handling the exception.
     131The resumption exception, @channel_closed@, has a couple fields to aid in handling the exception.
    105132The exception contains a pointer to the channel it was thrown from, and a pointer to an element.
    106133In exceptions thrown from remove the element pointer will be null.
    … …  
    116143Both of these examples are implemented using \CFA syntax so that they can be easily compared.
    117144Listing~\ref{l:go_chan_bar} uses go-style channel close semantics and Listing~\ref{l:cfa_chan_bar} uses \CFA close semantics.
    118 In 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.
     145In this problem it is infeasible to use the Go @close@ call since all tasks are both potentially producers and consumers, causing panics on close to be unavoidable.
    119146As 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.
    120147This sentinel value has to be checked at two points.
    121 Furthermore, an additional flag \code{done} is needed to communicate to threads once they have left the barrier that they are done.
     148Furthermore, an additional flag @done@ is needed to communicate to threads once they have left the barrier that they are done.
    122149This 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.
    123150In 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.
    … …  
    247274
    248275In Listing~\ref{l:cfa_resume} an example of channel closing with resumption is used.
    249 This program uses resumption in the \code{Consumer} thread main to ensure that all elements in the channel are removed before the consumer thread terminates.
    250 The 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.
     276This program uses resumption in the @Consumer@ thread main to ensure that all elements in the channel are removed before the consumer thread terminates.
     277The producer only has a @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.
    251278If 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.

    29 First proposed by Brinch Hansen~\cite{Hansen73} and later described and extended by C.A.R.~Hoare~\cite{Hoare74}, 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}.

    3031In 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.
    3132
    3233Figure~\ref{f:AtomicCounter} shows a \CFA and Java monitor implementing an atomic counter.
    3334A \Newterm{monitor} is a programming technique that implicitly binds mutual exclusion to static function scope by call and return.
    34 Lock mutual exclusion, defined by acquire/release calls, is independent of lexical context (analogous to block versus heap storage allocation).
     35In contrast, lock mutual exclusion, defined by acquire/release calls, is independent of lexical context (analogous to block versus heap storage allocation).
    3536Restricting acquire and release points in a monitor eases programming, comprehension, and maintenance, at a slight cost in flexibility and efficiency.
    3637Ultimately, a monitor is implemented using a combination of basic locks and atomic instructions.
    … …  
    110111To increase locking flexibility, some languages introduce a mutex statement.
    111112\VRef[Figure]{f:ReadersWriter} shows the outline of a reader/writer lock written as a \CFA monitor and mutex statements.
    112 (The exact lock implement is irrelevant.)
     113(The exact lock implementation is irrelevant.)
    113114The @read@ and @write@ functions are called with a reader/write lock and any arguments to perform reading or writing.
    114115The @read@ function is not MX because multiple readers can read simultaneously.
    … …  
    271272The @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.
    272273This repeats after selecting a new starting point in a cyclic manner until all locks are acquired successfully.
    273 This deadlock avoidance algorithm is shown in Listing~\ref{l:cc_deadlock_avoid}.
     274This deadlock avoidance algorithm is shown in Figure~\ref{f:cc_deadlock_avoid}.
    274275The algorithm is taken directly from the source code of the @<mutex>@ header, with some renaming and comments for clarity.

    336341Comparatively, 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.

    348353To 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.
    349354The benchmarks are run for a fixed duration of 10 seconds and then terminate.

    352357The median is calculated and is plotted alongside the 95\% confidence intervals for each point.

    375403Figure~\ref{f:mutex_bench} shows the results of the benchmark experiments.
    376 \PAB{Make the points in the graphs for each line different.
    377 Also, make the text in the graphs larger.}
    378404The 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.
    379405The avoidance result for both languages is significantly different, where \CFA's mutex statement achieves throughput that is magnitudes higher than \CC's @scoped_lock@.
    … …  
    383409For 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.
    384410It 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.
    385 In Figures~\ref{f:mutex_bench8_AMD} and \ref{f:mutex_bench8_Intel} the mutex statement performs better than the baseline.
    386 At 7 locks and above the mutex statement switches from a hard coded sort to insertion sort.
    387 It 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.
     411In 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.
     412At 7 locks and above the mutex statement switches from a hard coded sort to insertion sort, which should decrease performance.
     413It 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.
