Well, no. What I would want is, say, MPI variation of "hello world"

Or possibly some trivial implementation of poisson method, adapted for
such an environment?
It's just that I won't be capable to write this myself in the
foreseeable future, and I need to test the new installations. I wasn't
able to find something like this in the net.
Open MPI contains two test programs: "hello world" and "ring" in each
of the 4 languages (C, C++, F77, F90) in the examples/ directory.
Would those work for you? The "ring" message passes an integer
message around in a ring; if the message passing is not working
properly in a heterogeneous environment, then this program will
certainly fail (the integer message is how many more times to send the
message around the ring).
