Michael,

I finally had a chance to test rdma_bw....and it didn't work :^(
This was running r2519 IB kernel drivers, libibverbs, libmthca.

Here is the rdma_bw output on HP IA64 ZX1 (rx2600) machines:

rdma_lat test does work. I'll post results in a seperate
email since there is a bit more discussion around those results.

thanks,
