Hi, I think I've found a bug in the hear revision of the OpenMPI 1.5 branch. If it is configured with --disable-debug it crashes in finalize on the hello_c.c example. Did I miss something out?
Configure options: ./configure --with-pmi=/usr/ --with-slurm=/usr/ --without-psm --disable-debug --enable-mpirun-prefix-by-default --prefix=/hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install Runtime command and output: LD_LIBRARY_PATH=$LD_LIBRARY_PATH:../lib ./mpirun --mca btl openib,self --npernode 1 --host mir1,mir2 ./hello Hello, world, I am 0 of 2 Hello, world, I am 1 of 2 [mir1:05542] *** Process received signal *** [mir1:05542] Signal: Segmentation fault (11) [mir1:05542] Signal code: Address not mapped (1) [mir1:05542] Failing at address: 0xe8 [mir2:10218] *** Process received signal *** [mir2:10218] Signal: Segmentation fault (11) [mir2:10218] Signal code: Address not mapped (1) [mir2:10218] Failing at address: 0xe8 [mir1:05542] [ 0] /lib64/libpthread.so.0() [0x390d20f4c0] [mir1:05542] [ 1] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(+0x1346a8) [0x7f4588cee6a8] [mir1:05542] [ 2] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(opal_hwloc_base_close+0x32) [0x7f4588cee700] [mir1:05542] [ 3] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(opal_finalize+0x73) [0x7f4588d1beb2] [mir1:05542] [ 4] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(orte_finalize+0xfe) [0x7f4588c81eb5] [mir1:05542] [ 5] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(ompi_mpi_finalize+0x67a) [0x7f4588c217c3] [mir1:05542] [ 6] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(PMPI_Finalize+0x59) [0x7f4588c39959] [mir1:05542] [ 7] ./hello(main+0x69) [0x4008fd] [mir1:05542] [ 8] /lib64/libc.so.6(__libc_start_main+0xfd) [0x390ca1ec5d] [mir1:05542] [ 9] ./hello() [0x4007d9] [mir1:05542] *** End of error message *** [mir2:10218] [ 0] /lib64/libpthread.so.0() [0x3a6dc0f4c0] [mir2:10218] [ 1] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(+0x1346a8) [0x7f409f31d6a8] [mir2:10218] [ 2] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(opal_hwloc_base_close+0x32) [0x7f409f31d700] [mir2:10218] [ 3] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(opal_finalize+0x73) [0x7f409f34aeb2] [mir2:10218] [ 4] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(orte_finalize+0xfe) [0x7f409f2b0eb5] [mir2:10218] [ 5] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(ompi_mpi_finalize+0x67a) [0x7f409f2507c3] [mir2:10218] [ 6] /hpc/home/USERS/senina/projects/distribs/openmpi-svn_v1.5/install/lib/libmpi.so.1(PMPI_Finalize+0x59) [0x7f409f268959] [mir2:10218] [ 7] ./hello(main+0x69) [0x4008fd] [mir2:10218] [ 8] /lib64/libc.so.6(__libc_start_main+0xfd) [0x3a6d41ec5d] [mir2:10218] [ 9] ./hello() [0x4007d9] [mir2:10218] *** End of error message *** -------------------------------------------------------------------------- mpirun noticed that process rank 0 with PID 5542 on node mir1 exited on signal 11 (Segmentation fault). --------------------------------------------------------------------- Thanks, Andrew Senin
