PVM is a rather old and dated IPC for systems like Beowulf. As a matter
of fact, MPI was created to be a more portable, standard replacement.
PVM is still used in the sense that Fortran is still used (ironically,
it is probably old Fortran programmers that are familiar with PVM).

Beowulf clustered systems can communicate multitudes of other ways...
Shared memory probably being one, but also SysV IPC if I am not mistaken.
