Configure Option: --enable-sysv MCA Parameter: mpi_common_sm mpi_common_sm accepts a comma delimited list of: [sysv],mmap (order dependent). The first component that is successfully selected is used. For example, -mca mpi_common_sm sysv,mmap will first try sysv. If sysv is not successfully selected, then mmap will be used. mmap will be used if mpi_common_sm is not provided. Notes: Please make certain that your system's shmmax limit, or equivalent, is larger than mpool_sm_min_size. Otherwise, shmget may fail. This commit was SVN r23260.
