Parallelism and Concurrency in Haskell

Haskell supports both pure parallelism and explicit concurrency. How would you like to begin?

Speed up your code by making it run on multicore:
Start with Control.Parallel (pseq, par) and refine with Strategies
Manage simultaneous IO actions (eg. multiple connections on a web server)
Start with Concurrent Haskell (forkIO, MVar)
Work with clusters or do distributed programming
Distributed programming is still ongoing research. See below for current efforts.

In the meantime, you could use the Haskell MPI bindings, which use Concurrent Haskell and the MPI library.

Threadscope - parallel programs not getting faster? Use the Threadscope debugger and watch sparks fly.
