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.
