Hi Llolsten,
We are trying to keep up with the latest Open MPI as we can and keep a
few old versions around (oldest is 1.6), with RHEL 6.5. The OFED upgrade
will complement planned OS upgrades to the latest stable RHEL 6.x
(probably 6.7, not sure if we will go with 6.8).
Did you have to recompile Open MPI stacks or any of the existing MPI
software?
Thank you for your input!

Hello Mehmet,
OFED is now around 3.18.2-rc2 and there is talk of an rc3.
We have used many different versions of OFED, and we are now running
OFED 3.18.1 rc2 with the latest version of Open MPI with no trouble
(OS is CentOS 7.2). What version of Open MPI are you planning to use?
What OS, and version?
Good luck.

*Subject:* [OMPI users] Big jump from OFED 1.5.4.1 -> recent (stable).
Any suggestions?
Greetings!
We have not upgraded our OFED stack for a very long time, and still
running on an ancient version (1.5.4.1, yeah we know). We are now
considering a big jump from this version to a tested and stable recent
version and would really appreciate any suggestions from the community.
In particular, is there a particular recent OFED version that's known
to work well with Open MPI? Any versions we need to avoid? Do we need
to recompile existing Open MPI stacks? How about existing scientific
software that are compiled with it?
We will appreciate *any* suggestions/warnings (horror stories?) that
you won't mind sharing.
Thank you very much in advance!
