Hi, I recognized another problem with procecss bindings. The command works, if I use "-host" and it breaks, if I use "-hostfile" with the same machines.
tyr fd1026 178 mpiexec -report-bindings -host sunpc0,sunpc1 -np 4 \ -cpus-per-proc 2 -bind-to-core hostname sunpc1 [sunpc1:00086] MCW rank 1 bound to socket 0[core 0-1]: [B B][. .] [sunpc1:00086] MCW rank 3 bound to socket 1[core 0-1]: [. .][B B] sunpc0 [sunpc0:10929] MCW rank 0 bound to socket 0[core 0-1]: [B B][. .] sunpc0 [sunpc0:10929] MCW rank 2 bound to socket 1[core 0-1]: [. .][B B] sunpc1 tyr fd1026 179 cat host_sunpc0_1 sunpc0 slots=4 sunpc1 slots=4 tyr fd1026 180 mpiexec -report-bindings -hostfile host_sunpc0_1 -np 4 \ -cpus-per-proc 2 -bind-to-core hostname -------------------------------------------------------------------------- An invalid physical processor ID was returned when attempting to bind an MPI process to a unique processor. This usually means that you requested binding to more processors than exist (e.g., trying to bind N MPI processes to M processors, where N > M). Double check that you have enough unique processors for all the MPI processes that you are launching on this host. You job will now abort. -------------------------------------------------------------------------- sunpc0 [sunpc0:10964] MCW rank 0 bound to socket 0[core 0-1]: [B B][. .] sunpc0 [sunpc0:10964] MCW rank 1 bound to socket 1[core 0-1]: [. .][B B] -------------------------------------------------------------------------- mpiexec was unable to start the specified application as it encountered an error on node sunpc0. More information may be available above. -------------------------------------------------------------------------- 4 total processes failed to start Perhaps this error is related to the other errors. Thank you very much for any help in advance. Kind regards Siegmar
