Hi to all, I am using the same subject of a recent message I found in the list archives of this mailing list:
http://www.open-mpi.org/community/lists/users/2008/10/7025.php There was no follow-up on that one, but will add this similar report in case a list member can give us an idea of how to correct it. Or whose bug this could be. My application behaves as expected when I run it in a single host and multiple MPI nodes of our SGI Altix ICE 8200 cluster with in InfiniBand. When I try the same with multiple hosts, using the PBS batch system the program terminates with a segmentation fault: ------- [r1i0n9:09192] *** Process received signal *** [r1i0n9:09192] Signal: Bus error (7) [r1i0n9:09192] Signal code: (2) [r1i0n9:09192] Failing at address: 0x2b67ca0c8c20 [r1i0n9:09192] [ 0] /lib64/libpthread.so.0 [0x2b67bfdb1c00] [r1i0n9:09192] [ 1] /sw/openmpi_intel/1.2.8/lib/libmpi.so.0(ompi_free_list_grow+0x14a) [0x2b67bf499b38] [r1i0n9:09192] [ 2] /sw/openmpi_intel/1.2.8/lib/openmpi/mca_btl_sm.so(mca_btl_sm_alloc+0x321) [0x2b67c3a43e15] [r1i0n9:09192] [ 3] /sw/openmpi_intel/1.2.8/lib/openmpi/mca_pml_ob1.so(mca_pml_ob1_send_request_start_copy+0x26d) [0x2b67c34e9041] [r1i0n9:09192] [ 4] /sw/openmpi_intel/1.2.8/lib/openmpi/mca_pml_ob1.so(mca_pml_ob1_isend+0x540) [0x2b67c34e17ec] [r1i0n9:09192] [ 5] /sw/openmpi_intel/1.2.8/lib/libmpi.so.0(PMPI_Isend+0x63) [0x2b67bf4dcd1f] [r1i0n9:09192] [ 6] /sw/openmpi_intel/1.2.8/lib/libmpi_f77.so.0(pmpi_isend+0x8f) [0x2b67bf36a03f] [r1i0n9:09192] [ 7] dsimpletest(dmumps_comm_buffer_mp_dmumps_519_+0x449) [0x53e19b] [r1i0n9:09192] [ 8] dsimpletest(dmumps_load_mp_dmumps_512_+0x20b) [0x54fda1] [r1i0n9:09192] [ 9] dsimpletest(dmumps_251_+0x4995) [0x4d273b] [r1i0n9:09192] [10] dsimpletest(dmumps_244_+0x808) [0x484e38] [r1i0n9:09192] [11] dsimpletest(dmumps_142_+0x8717) [0x4bf5eb] [r1i0n9:09192] [12] dsimpletest(dmumps_+0x1554) [0x43a720] [r1i0n9:09192] [13] dsimpletest(MAIN__+0x50b) [0x41e4c3] [r1i0n9:09192] [14] dsimpletest(main+0x3c) [0x683d4c] [r1i0n9:09192] [15] /lib64/libc.so.6(__libc_start_main+0xf4) [0x2b67bfeda184] [r1i0n9:09192] [16] dsimpletest(dtrmv_+0xa1) [0x41df29] [r1i0n9:09192] *** End of error message *** ---- Most of the software infrastructure is provided by the Intel propack.
