Off-topic, and surely better on the Beowulf list, it's answered
somewhere in the OFED docs:  Make the MTRR setting `discrete' (under the
CPU parameters in the AMI BIOS versions with which I'm familiar).

I can't think of a suitable Ob-OMPI.

[OMPI users] x4100 with IB

[Michael Di Domenico]

I have several Sun x4100 with Infiniband which appear to be running at
400MB/sec instead of 800MB/sec.  It a freshly reformatted cluster
converting from solaris to linux.  We also reset the bios settings
with "load optimal defaults". Does anyone know which bios setting i
changed to dump the BW?
