That is wonderful, that fixes the observed problem for running with
OB1. Has a bug for this been filed to get RDMA working on macs?
The only working MPI lib is MPICH-GM as this problem happens with
LAM-7.1.3 also.
So on track for one bug.
Would the person working on the DR PML like me to try anymore tests?

Brock and Galen,
We are willing to assist. Our best guess is that OMPI is using the
code in a way different than MPICH-GM does. One of our other
developers who is more comfortable with the GM API is looking into
it.
We tried running with HPCC with:
$ mpirun -np 4 -machinefile hosts -mca btl ^tcp -mca
btl_gm_min_rdma_size $((10*1024*1024)) ./hpcc.ompi.gm
and HPL passes. The problem seems to be in the RDMA fragmenting code
on OSX. The boundary values at the edges of the fragments are not
correct.
