What I need is one MPI job put for distributed
computation on several actual machines,
connected by TCP/IP (so, kind of cluster
computation). Machines may have heterogenous
OSes on them (MP-MPICH accounts for that with
its HETERO option).

I'm somewhat new to MPI. It's possible, that
what I describe is an inherent option of MPI
implementations. Please advise.
