Synopsis: A library for parallel programming based on a monad
-- Version history:
-- 0.1 : First release
-- 0.1.0.1 :
-- 0.1.0.2 :
-- 0.1.1.0 : module reorganization, moving ParClass
-- 0.2 : Bumped for new class-based API
-- 0.2.1 : Bumped for change AList
-- 0.2.2 : incorporation of real deque package
-- 0.2.3 : Restricted module export for 0.2 release.
-- 0.3 : Factored/reorganized modules and packages.
-- *This* package is the original, core monad-par.
-- 0.3.1 : fix for ghc 7.6.1, expose Par.IO
-- 0.3.4 : switch to direct scheduler as default (only 1-level nesting allowed)
-- 0.3.4.1 : fix build with GHC 7.0, and fix test
-- 0.3.4.2 : Bugfix, 0.3.4.1 was released with debugging switches flipped.
-- 0.3.4.3 : Bugfix, Trace scheduler is now the default
-- 0.3.4.4 : Use the Trace scheduler in Control.Monad.Par.IO too
-- 0.3.4.5 : Extremely minor, fix to unit tests.
-- 0.3.4.6 : Add newgeneric flag, supporting the par-classes module.
-- 0.3.4.7 : bugfix #38 for GHC 7.10
Description:
The 'Par' monad offers a simple API for parallel programming. The
library works for parallelising both pure and @IO@ computations,
although only the pure version is deterministic. The default
implementation provides a work-stealing scheduler and supports
forking tasks that are much lighter weight than IO-threads.
.
For complete documentation see "Control.Monad.Par".
.
Some examples of use can be found in the @examples/@ directory of
the source package.
.
Other related packages:
.
* @abstract-par@ provides the type classes that abstract over different
implementations of the @Par@ monad.
.
* @monad-par-extras@ provides extra combinators and monad transformers layered on top of
the @Par@ monad.
.
Changes in 0.3.4 relative to 0.3:
.
* Fix bugs that cause "thread blocked indefinitely on MVar" crashes.
.
* Added "Control.Monad.Par.IO"

Library
Exposed-modules:
-- The classic, simple monad-par interface:
Control.Monad.Par
, Control.Monad.Par.IO
-- This is the default scheduler:
, Control.Monad.Par.Scheds.Trace
, Control.Monad.Par.Scheds.TraceInternal
-- Replacement scheduler for Trace:
, Control.Monad.Par.Scheds.Direct
-- This scheduler uses sparks rather than IO threads.
-- It only supports Futures, not full IVars. Fork
-- becomes lighter weight.
, Control.Monad.Par.Scheds.Sparks
-- Needs MonadIO (in transformers, but not imported here)
Build-depends: base >= 4.9 && < 5
-- This provides the interface which monad-par implements:
, abstract-par
, abstract-deque >= 0.1.4
-- Extras such as parMap, RNG, State
, monad-par-extras >= 0.3
, deepseq >= 1.1
, array >= 0.3
, mwc-random >= 0.11
, containers
, parallel >= 3.1

-- Schedulers & Infrastructure --
------------------------------------------------------------
-- Strawman scheduler that forks IO threads:
-- Control.Monad.Par.Scheds.ContFree,
-- Internal logging framework:
-- Control.Monad.Par.Logging,
-- Serial Elision scheduling is currently experimental:
-- Control.Monad.Par.Scheds.SerialElision
Control.Monad.Par.Scheds.DirectInternal
------------------------------------------------------------
-- Data Structures --
------------------------------------------------------------
-- ILists are internal:
-- , Control.Monad.Par.IList
-- RRN: Not exposing Streams or OpenLists yet. Need to improve performance.
-- We have some ideas for enabling bounded chans while preventing deadlock:
-- , Control.Monad.Par.OpenList
-- , Control.Monad.Par.Stream
