I think PVM3.3.8 for SP/2 is implemented on MPI because I downloaded three month ago
a beta version of PVM3.3. This beta version needs 'mpicc' to compile. So you need to 
install MPICH before installing PVM3.3.8 (if you want to use the High Performance 
Switch of your IBM SP).

There is only a problem with PVMe: PVMe is *not* up to date.
But we have obtained better performance with PVMe (*8-10) for bandwith and latency than 
PVM.
So we intensively use PVMe.

May be we 'll use PVM3.3.8 (rather than PVMe) in the future because the person who has
given me the beta version of PVM for SP said me: The performances are better with PVM for
SP than with PVMe. Is anyone has observed this?

At this time, we need to install and test it. But the problem is that I can't install 
MPICH because of a xlc bug. (I'm waiting for a PTF from IBM to fix the bug).
