Dear all, We are testing Open MPI over Infiniband, and got a MPI_Reduce error message when we run our codes either over TCP or Infiniband interface, as follows,
--- [gulftown:25487] *** An error occurred in MPI_Reduce [gulftown:25487] *** on communicator MPI COMMUNICATOR 3 CREATE FROM 0 [gulftown:25487] *** MPI_ERR_ARG: invalid argument of some other kind [gulftown:25487] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort) Elapsed time: 6:33.78 <Done> -------------------------------------------------------------------------- mpirun has exited due to process rank 0 with PID 25428 on node gulftown exiting without calling "finalize". This may have caused other processes in the application to be terminated by signals sent by mpirun (as reported here). -------------------------------------------------------------------------- --- Any hints? Thanks, Yiguang
