Also, Brice Goglin, the Open-MX author had a couple of questions
concerning multi-rail MX while I'm on:
1. Does the MX MTL work with multi-rail?
I believe the answer is yes as long as all NICs are in the same fabric
(they usually are).
2. "You may also want to ask why the MX BTL seems to be opening and
closing an additional endpoint during initialization. It seems to
make endpoint numbers a bit unpredictable here (causing my jobs to
use the wrong rail"
Thanks for any info.
Without knowing the code and/or looking, I believe OMPI opens an
endpoint to get some mapping info (to see if the NIC is in the same
fabric).
