Hi Arthur,
I use mpi for parallelizing some moderately-sized number crunching
tasks (kd-tree queries over trees of size ~1e5 points. I have primarily
used the scatter/gather collective operations for this. Of course, MPI is a
bit low-level for a functional programming language, and one day I hope to
develop some high level abstractions over the basic MPI functionality. If
you have some idea what kind of concurrent patterns you want to use in your
application, I can suggest which MPI functions may be of use to you.
