Hello, I've been having some troubles with OpenMPI 1.4.X and slurm recently. I seem to be able to run jobs this way ok: --- sh-3.1$ mpirun -np 2 mpi_hello Hello, I am node cut1n7 with rank 0 Hello, I am node cut1n8 with rank 1 --
However if I try and use the -npernode option I get: --- sh-3.1$ mpirun -npernode 1 mpi_hello [cut1n7:16368] *** Process received signal *** [cut1n7:16368] Signal: Segmentation fault (11) [cut1n7:16368] Signal code: Address not mapped (1) [cut1n7:16368] Failing at address: 0x50 [cut1n7:16368] [ 0] /lib64/libpthread.so.0 [0x37bda0de80] [cut1n7:16368] [ 1] /apps/mpi/openmpi/1.4.2-gcc-4.1.2-may.12.10/lib/libopen-rte.so.0(orte_util_encode_pidmap+0xdb) [0x2b73eb84df8b] [cut1n7:16368] [ 2] /apps/mpi/openmpi/1.4.2-gcc-4.1.2-may.12.10/lib/libopen-rte.so.0(orte_odls_base_default_get_add_procs_data+0x655) [0x2b73eb8592f5] [cut1n7:16368] [ 3] /apps/mpi/openmpi/1.4.2-gcc-4.1.2-may.12.10/lib/libopen-rte.so.0(orte_plm_base_launch_apps+0x10b) [0x2b73eb86031b] [cut1n7:16368] [ 4] /apps/mpi/openmpi/1.4.2-gcc-4.1.2-may.12.10/lib/openmpi/mca_plm_slurm.so [0x2b73ec709ecf] [cut1n7:16368] [ 5] mpirun [0x40335a] [cut1n7:16368] [ 6] mpirun [0x4029f3] [cut1n7:16368] [ 7] /lib64/libc.so.6(__libc_start_main+0xf4) [0x37bce1d8b4] [cut1n7:16368] [ 8] mpirun [0x402929] [cut1n7:16368] *** End of error message *** Segmentation fault --- This is ompi 1.4.2, gcc 4.1.1 and slurm 2.0.9 ... I'm sure it's a rather silly detail on my end, but figure I should start this thread for any insights and feedback I can help provide to resolve this. Thanks, -cdm
