That's a pretty old version of slurm - I don't have access to anything that old to test against. You could try running it with --display-allocation --display-devel-map to see what ORTE thinks the allocation is and how it mapped the procs. It sounds like something may be having a problem there...
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_helloHello, I am node cut1n7 with rank 0Hello, 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
