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

We also reset the bios settings with "load optimal defaults". Does anyone know which bios setting i changed to dump the BW? x4100 mellanox ib ofed-1.4.1-rc6 w/ openmpi
