Subject: [OMPI devel] CMR one-sided changes? (r21134)

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 (
). 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...
