Single node straightforward benchmarks for comex-ofa mpi-pr and mpi-spawn
The same settings above, with new ARMCI_NETWORK settings. 

armci-openmp:Total times  cpu:     6649.3s     wall:     6382.4s
comex-ofa:Total times  cpu:     6801.7s     wall:     6445.6s
mpi-spawn:Total times  cpu:     6718.9s     wall:     6483.8s
mpi-pr:Total times  cpu:     6667.2s     wall:     6428.9s


These communication methods seem to provide a performance-wise viable alternative if you are having issues with ARMCI_DEFAULT_SHMMAX
