Brian: can we CMR over your OSD changes from 30 Apr (r21134)?
I have noticed an enormous performance difference between the pt2pt
and rdma osc components when running the IMB-EXT benchmark over IB:
- pt2pt: 11+ minutes
- rdma: 43 seconds
rdma is the default on the trunk, since r21134 (https://svn.open-mpi.org/trac/ompi/changeset/21134
). pt2pt is still the default on v1.3.
There's a conflict in ompi/mca/osc/rdma/osc_rdma_sync.c, so I don't
quite know how to proceed...
