libghc-monad-par-extras-prof 0.3.3-7build1 (amd64 binary) in ubuntu zesty

 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, compiled
 for profiling. See http://www.haskell.org/ for more information on Haskell.
