You're right! 'Standard' versions of PVM 2.x or 3.x work
perfectly on the SP1 but only via the IP protocol. If you
want the full performance and, by the way, use the high-speed
switch, you'll have to buy the IBM PVMe (PVM enhanced) system.
Up to now, PVMe is compatible with PVM 2.4.2 and PVMe 2.0
will be compatible with 3.2.x.
