Description:
Combinators and extra features for Par monads
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. . This package provides combinators and extra features for Par monads. . This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
