- I'd like to correct this. PVM 2.3 and 2.4 do NOT run on the iPSC/860, iPSC/2
- or CM-2. They DO run on the hosts of these machines, which is an entirely
- different matter. Since PVM provides a SPMD/MIMD model, it is highly
- unlikely that it will ever run "on" a CM-2. Saying that it runs on these
- machines is highly misleading at best.

- See <pvddir>/doc/FAQ for the 2.4.1 version; this file acknowledges that
- PVM doesn't actually run on these machines. It does however confuse
- implementation restrictions with semantic restrictions; for a counter-example,
- see P4 or Express.
