Hi, I found that ./openmpi-1.4.3/ompi/runtime/ompi_mpi_init.c was changed. Calling opal_progress_event_users_decrement was deleted as below.
$diff openmpi-1.4.2/ompi/runtime/ompi_mpi_init.c openmpi-1.4.3 /ompi/runtime/ompi_mpi_init.c 813,819d812 < /* Undo ORTE calling opal_progress_event_users_increment() during < MPI lifetime, to get better latency when not using TCP. Do < this *after* dyn_init, as dyn init uses lots of ORTE < communication and we don't want to hinder the performance of < that code. */ < opal_progress_event_users_decrement(); < I confirmed that this change affects SYSTEM CPU & performace decrement. Is it safe to replace the routine with older one? Anyway, if it's just a mistake, please fix it in the next version. Regards, Tetsuya Mishima
