This version can be pinned in stack with:monad-par-0.3.6@sha256:e7a8c6412ffa14debd61c16b77eb416a3e0bbce0418ae682e86e1575c84b6258,6716

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.

Changes in 0.3.4 relative to 0.3:
