Well, no. What I would want is, say, MPI variation of "hello world" that
would output the phrase char by char, one char per the participating
host, and doing it in correct (so, MPI-synchronised) order. Hosts may be
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.
