This page collects examples of concurrent and parallel programming in Haskell.

Contents

[edit] 1 Examples

[edit] 2 More examples

A large range of small demonstration programs for using concurrent and

parallel Haskell are in the Haskell concurrency regression tests. In particular, they show the use of
MVars
and
forkIO
.

[edit] 3 Proposed updates

The base 3.0.3.1 package's Control.Concurrent.QSem and QSemN are not exception safe. The SafeConcurrent has the proposed replacement code.
