$HOSTNAME is not getting set for some reason, so that method didn't
work when I first tried it [using getenv ("HOSTNAME") the result was
null]
gethostname () worked fine though, thanks to the recommendations of
some very helpful lam mailing list people :-)
I'll try MPI_Get_processor_name () when I get back, just to know how it works.
Thanks,
