[mvapich-discuss] IB benchmarks that are a bit strange

[Brian Budge]

Hi all -

I am running the osu_bw bandwidth test on my small cluster.  I'm
seeing some slightly strange behavior:  Let's say I have nodes 0 and
1.  When I launch the bw test from node 0 and run the test on 0 and 1,
I see a max bandwidth of 650 MB/s.  However, when I run from node 1
and run the test on 0 and 1, I see a max bandwidth of close to 850
MB/s.  Does anyone know how I might diagnose/fix this issue?  Has
anyone seen it before?

Thanks,
  Brian
