Ick - talk about confusing! I suppose there must be -some- rational reason why someone would want to do this, but I can't imagine what it would be....
I'm no expert on compiler vs lib confusion, but some of my own experience would say that this is a bad idea regardless of whether or not OMPI is involved. Compiler version interoperability is usually questionable, depending upon how far apart the rev levels are. Only answer I can offer is that you would have to try it. It will undoubtedly be a case-by-case basis: some combinations might work, others might fail. On Aug 12, 2010, at 3:53 PM, Michael E.
