Hi today I have installed openmpi-1.6.4rc3r27923. Unfortunately I still have a problem with rankfiles, if I start a process on a remote machine.
tyr rankfiles 114 ssh linpc1 ompi_info | grep "Open MPI:" Open MPI: 1.6.4rc3r27923 tyr rankfiles 115 cat rf_linpc1 rank 0=linpc1 slot=0:0-1,1:0-1 tyr rankfiles 116 mpiexec -report-bindings -np 1 \ -rf rf_linpc1 hostname ------------------------------------------------------------------ All nodes which are allocated for this job are already filled. ------------------------------------------------------------------ The following command still works. tyr rankfiles 119 mpiexec -report-bindings -np 1 -host linpc1 \ -cpus-per-proc 4 -bycore -bind-to-core hostname [linpc1:32262] MCW rank 0 bound to socket 0[core 0-1] socket 1[core 0-1]: [B B][B B] linpc1 tyr rankfiles 120 Everything is fine, if I use the rankfile on the local machine. linpc1 rankfiles 103 ompi_info | grep "Open MPI:" Open MPI: 1.6.4rc3r27923 linpc1 rankfiles 104 cat rf_linpc1 rank 0=linpc1 slot=0:0-1,1:0-1 linpc1 rankfiles 105 mpiexec -report-bindings -np 1 \ -rf rf_linpc1 hostname [linpc1:32385] MCW rank 0 bound to socket 0[core 0-1] socket 1[core 0-1]: [B B][B B] (slot list 0:0-1,1:0-1) linpc1 linpc1 rankfiles 106 In my opinion it should also work if I start a process on a remote machine. Can somebody look once more into this issue? Thank you very much for your help in advance. Kind regards Siegmar
