Hello,

	Has anybody experienced any problems in executing a PVM 3.3.7
program over a cluster of RS6Ks?

	I have a large CFD code which runs okay over a cluster of SGI Indys.
But when I recompile it for the RS6K and I try to execute it, I get : 

> Illegal instruction (core dumped)

	When I comment out large 'non-pvm' portions of my code and leave 
just the skelton of the PVM program, I don't get this problem.  Is there 
something wrong with the xlf compiler?

	Any ideas?  I'm clueless.  Any help would be appreciated.  Thanks.
