Hi, I have built mpich-master-v3.2-331-g44fd9c5f39e5 on my machines (Solaris 10 Sparc, Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with gcc-5.1.0 and Sun C 5.13. Most of the time I get an error with different error messages spawning processes on a Sparc machine. tyr spawn 107 mpiexec -np 1 --host tyr,tyr,tyr,tyr,tyr spawn_master Parent process 0 running on tyr.informatik.hs-fulda.de I create 4 slave processes Parent process 0: tasks in MPI_COMM_WORLD: 1 tasks in COMM_CHILD_PROCESSES local group: 1 tasks in COMM_CHILD_PROCESSES remote group: 4 Slave process 0 of 4 running on tyr.informatik.hs-fulda.de Slave process 1 of 4 running on tyr.informatik.hs-fulda.de Slave process 2 of 4 running on tyr.informatik.hs-fulda.de Slave process 3 of 4 running on tyr.informatik.hs-fulda.de spawn_slave 0: argv[0]: spawn_slave spawn_slave 1: argv[0]: spawn_slave spawn_slave 2: argv[0]: spawn_slave spawn_slave 3: argv[0]: spawn_slave tyr spawn 108 mpiexec -np 1 --host tyr,tyr,tyr,tyr,tyr spawn_master Parent process 0 running on tyr.informatik.hs-fulda.de I create 4 slave processes Fatal error in MPI_Comm_spawn: Unknown error class, error stack: MPI_Comm_spawn(141)...................: MPI_Comm_spawn(cmd="spawn_slave", argv=0, maxprocs=4, MPI_INFO_NULL, root=0, MPI_COMM_WORLD, intercomm=ffffffff7fffdf58, errors=0) failed MPIDI_Comm_spawn_multiple(274)........: MPID_Comm_accept(153).................: MPIDI_Comm_accept(1039)...............: MPIDU_Complete_posted_with_error(1137): Process failed tyr spawn 109 tyr spawn 111 mpiexec -np 1 --host tyr,tyr,tyr,tyr,tyr spawn_master Parent process 0 running on tyr.informatik.hs-fulda.de I create 4 slave processes =================================================================================== = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = PID 3322 RUNNING AT tyr = EXIT CODE: 10 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES =================================================================================== [proxy:0:[email protected]] HYD_pmcd_pmip_control_cmd_cb (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/pm/pmiserv/pmip_cb.c:883): assert (!closed) failed [proxy:0:[email protected]] HYDT_dmxu_poll_wait_for_event (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/tools/demux/demux_poll.c:77): callback returned error status [proxy:0:[email protected]] main (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/pm/pmiserv/pmip.c:202): demux engine error waiting for event [[email protected]] HYDT_bscu_wait_for_completion (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/tools/bootstrap/utils/bscu_wait.c:76): one of the processes terminated badly; aborting [[email protected]] HYDT_bsci_wait_for_completion (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/tools/bootstrap/src/bsci_wait.c:23): launcher returned error waiting for completion [[email protected]] HYD_pmci_wait_for_completion (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/pm/pmiserv/pmiserv_pmci.c:218): launcher returned error waiting for completion [[email protected]] main (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/ui/mpich/mpiexec.c:340): process manager error waiting for completion tyr spawn 112 I would be grateful if somebody can fix the problem.
