Just realised that in the failed test I posted I set -mca mpi_affinity_alone 1 *instead* of -mca paffinity linux, rather than as well as. Would that result in PLPA not being used ? Is there a debugging switch to get mpiexec to show what MCA modules are being loaded/used at runtime ? cheers, Chris -- Christopher Samuel - (03) 9925 4751 - Systems Manager The Victorian Partnership for Advanced Computing P.O.
