HOW:
MCA mpi: parameter "mpi_common_sm" (current value: <mmap>,
                           data source: default value)
                           Which shared memory support will be used.
Valid
                           values: sysv,mmap - or a comma delimited
combination
                           of them (order dependent). The first
component that
                           is successfully selected is used.

Thanks!
