Open MPI currently has a "negative ACK" kind of assumption built into
it -- it assumes that if you have high-speed network support built
into it, you'll want to know if you're not using it.
You're correct that you can disable this warning by setting the "btl"
MCA parameter to ^openib (or an
I'm running Intel's IMB benchmark over an InfiniBand cluster; though other
benchmarks that Open MPI has done fine in the past are also performing
poorly.
The cluster has DDR IB, and the fabric isn't seeing the kind of symbol errors
that indicate a bad fabric; (non-mpi) bandwidth tests over the

Hope this helps,
