The RDMA package in RHEL and RHEL clones != OFED. OFED is the full
distribution, whereas Red Hat merely cannibalizes pieces from them. The current
RDMA implementation within RHEL6.2 and clones is very old and doesn't even work
correctly with Mellanox QDR IB HCAs.

Subject: Re: [Oscar-users] Seeking OSCAR replacement (CentOS based preferred)
Hi,
Been installing xCAT for the past 2 years on various clusters (a couple of IBM
based X systems, but mostly SuperMicro twins and 2sqU).
In the SM HW, configuring IPMI (which is essential for xCAT management) is a
breath. Easy as pie (or insert whatever is equivalent to 2+2=4 in your culture).
Quite happy with it, but note that unless you purchase the IBM hpc package
(i.e. loadleveler at. al.) you have to install your own scheduler. I have been
installing and using slurm (with munge) and deployment is quite simple once you
build RPMS.
Same note regarding IB stack - although RH/SL/OL/CentOS all provide ofed RPMS
(and xCAT has a decent ib installation postscript), I prefer to build from
vanilla OFED, with latest openmpi srpms dropped into the SRPM dir "as-is".
works quite well.
All in all, for me (and the last 8 or so clusters I built) - xCAT + SLURM +
OFED was easy to install and maintain.

Hello,
OK. So it appears that Oscar is very much dead. Does anyone know of any
similar solutions which are still active?
I have come across two that appear to still be "alive": Rocks and Warewulf.
Does anyone know of any others? A lot of the others that I have been aware
of in the past (Oscar, Perceus, Caos, etc.) all lead to dead-ends web links or
bits
that are several years old.
Thanks in advance,
Steve Nash
