With Jeff and Ralph's help, I have completed a System V shared memory
component for Open MPI. I have conducted some preliminary tests on
our systems, but would like to get test results from a broader audience.
As it stands, mmap is the defaul, but System V shared memory can be
activated using: -mca mpi_common_sm sysv
Input is greatly appreciated!
