@hackage abstract-par0.3

The Par monad(s) offer an alternative parallel programming API to that provided by the parallel package. A Par monad allows the simple description of parallel computations, and can be used to add parallelism to pure Haskell code. The basic API is straightforward: a Par monad supports forking and simple communication in terms of IVars. This module is an interface module only. It provides a number of type clasess, but not an implementation. The type classes separate different levels of Par functionality. See the Control.Monad.Par.Class module for more details. The 'monad-par' library is one example of a concrete library providing this interface.
