Open MPI implements the MPI specification. Here is a link to a java implementation here.

MPI (http://en.wikipedia.org/wiki/Message_Passing_Interface) is not the same as OpenMP (http://en.wikipedia.org/wiki/OpenMP), but it targets the same problem.

It doesn't in fact. Both are complementary: basically mostly openmp for shared memory and mpi for distruibuted memory. The mix can give quite hairy codes though ^^

Question about this - Isn't jppf is to used when working with grid of computers, rather with one single computer with multiple threads?

I think most people just use threads and the in-built concurrency constructs to achieve parallelism in Java.

Sorry I can't point you to anything more high level, but you might find that using threads isn't too bad - it's done quite well in Java.
