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
Learn about concurrency first and then use the Haskell MPI bindings.
Meanwhile look out for ongoing research into distributed Haskell.

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