I see all the questions and ask myself:
Is the difference between OFED and the infiniband drivers in the CentOS repos tangible?
It depends. I found for most cases it is not worth the extra effort to use the
OFED/Mellanox stack.
Now if you have FDR Mellanox cards then yes using the Mellanox/OFED 3.12 stack makes a
difference.
We did have one cluster that was having problems with the RHEL infiniband stack and going
to the
Mellanox stack helped in that case.
We had the OFED problems and just switched to the CentOS drivers,
since all the clients are running with the Debian/kernel.org<http://kernel.org>
drivers it didn't seem to make a big difference anyhow...
