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 (par, pseq) and refine with Strategies

Find out more about parallelism basics
Manage simultaneous IO actions (eg. multiple connections on a web server)
Start with Concurrent Haskell (forkIO, MVar)

Find out more about concurrency basics
Work with clusters or do distributed programming
Learn about concurrency first, then try using network protocol libraries like HTTP or zeromq.

Meanwhile look out for ongoing research into distributed Haskell.

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