Hi Todd,
Better switch to OpenMPI as soon as possible.
I spent couple of days installing and then trying to run LAM 7.1.2 and
7.1.4 on the same computer and OS you have.
I managed to install LAM, then I was able to compile my parallel codes
BUT there was no way to run them.
Strange errors were reported and finally I gave up.
Jeff Squyres suggested to go for OpenMPI. I did it. NO MORE PROBLEMS
and everything works fine.
Regards,
Artur.
