OpenMP with OCAML

Question

Does anyone know if it's possible use OpenMP with OCaml source code?

Or another application/ambient of work, compatible with OCaml, that allows me to run parallel programs that exploit multiple cores?

If yes, how? Have you got an easy example?

Answer 1

Currently there is OC4MC (ocaml 4 multi-core) to perform shared memory multi-processing. I have not used the project, but there are fairly recent updates, so I can only assume the project is still moving forward.

JOCAML is another concurrent extension to ocaml implementing the join calculus. I have also not used this project, but their site is updated to mention ocaml 3.12, which came out fairly recently. Disregard; see comment.

If you can pry yourself away from the openMP paradigm, then there are ocaml bindings for mpi. I use this project, and have not had problems with it, and it's pretty easy to use if you are familiar with MPI.

Lastly, some (possibly unmaintained) packages pertaining to multi-core / parallel processing can be found on the ocaml hump.
