monad-par: A library for parallel programming based on a monad

[ bsd3, control, library, monads, parallelism ] [ Propose Tags ] [ Report a vulnerability ]

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.
