Hi I have installed openmpi-1.6.4rc2 and have still a problem with my rankfile.
linpc1 rankfiles 113 ompi_info | grep "Open MPI:" Open MPI: 1.6.4rc2r27861 linpc1 rankfiles 114 cat rf_linpc1 rank 0=linpc1 slot=0:0-1,1:0-1 linpc1 rankfiles 115 mpiexec -report-bindings -np 1 \ -rf rf_linpc1 hostname -------------------------------------------------------------------- We were unable to successfully process/set the requested processor affinity settings: Specified slot list: 0:0-1,1:0-1 Error: Error This could mean that a non-existent processor was specified, or that the specification had improper syntax. -------------------------------------------------------------------- -------------------------------------------------------------------- mpiexec was unable to start the specified application as it encountered an error: Error name: Error Node: linpc1 when attempting to start process rank 0. -------------------------------------------------------------------- Everything works fine with the following command. linpc1 rankfiles 116 mpiexec -report-bindings -np 1 -cpus-per-proc 4 \ -bycore -bind-to-core hostname [linpc1:20140] MCW rank 0 bound to socket 0[core 0-1] socket 1[core 0-1]: [B B][B B] linpc1 I would be grateful if somebody could fix the problem.
