A broad overview of all the abstractions available:

     http://haskell.org/haskellwiki/Applications_and_libraries/Concurrency_and_parallelism

Obviously, the most heavily used are those for shared-memory multicore
implemented and shipping with GHC (see e.g. the new rts papers). Things
like sparks, STM, MVars, and to some extent nested data parallelism, are
just there, out of the box.

A good paper on the rts support in GHC.

Followed by hackage libraries for different things (like actors).

Transparently distributed Haskell's are researchy, and someone else
should fill in the story there.
