TIMEOUT: Tuesday, June 8, 2010 (after devel concall). 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! -- Samuel K.
