Hi Joshua
Again, forwarded by the friendly elf - so include me directly in any reply.
I gather from Jeff that you are attempting to do something with bproc -
true? If so, I will echo what Jeff said: bproc support in OMPI is being
dropped with the 1.3 release due to lack of interest/support. Just
Hmmmthis email thread was forwarded to me by a friendly elf, so be sure
to include me directly in any reply. As the person who wrote a lot of the
bproc support, I'll try to catch up on it over the next couple of days.
One thing to correct right away, though. The --display-map function actually
Errr... That's not good. :-(

It could also have been that you didn't have exactly matching
installations on both machines. Even if they were the same version,
if they weren't configured / installed the same way on both machines,
this could have led to problems. Also be sure that either the MPI

That is a very weird stack trace. Is the application finishing and
