ocaml-parmap

Multicore architecture exploitation for OCaml programs with minimal modifications

If you want to use your many cores to accelerate an operation which happens to be a map, fold or map/fold (map-reduce), just use Parmap's parmap, parfold and parmapfold primitives in place of the standard List.map and friends; you can specify the number of subprocesses to use with the optional parameter ncores, and the size of granularity of the parallel computation with the optional parameter chunksize.
