Hmm, that is the way that I expected it to work as well -
we see the warnings also, but closely followed by the
errors (I've been trying both 1.2.5 and a recent 1.3
snapshot with the same behavior). You don't have the
mx driver loaded on the nodes that do not have a myrinet
card, do you?
Well, the driver isn't "loaded" (ie: the kernel module isn't loaded),
but the library (libmyriexpress.so) is available. If that library isn't
available, OpenMPI will probably fail when it tries to call the mx
functions (even if only to find there's no myrinet card available).
Yeah, that is much better - not having the mx software available on
the non-myrinet nodes was the main problem.
