Concurrency demos

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

Examples

• Riemann's Zeta function approximation
• Signal that you want to gracefully exit another thread
• Passing messages across a single chan to two readers

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.
