Hello everybody! I've Sun T5120 (SPARC64) Servers with - Debian: 6.0.3 - linux-2.6.39.4 (from kernel.org) - OFED-1.5.3.2 - InfiniBand: Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] (rev a0) with newest FW (2.9.1) and the following issue:
If I try to mpirun a program like the osu_latency benchmark: $ /usr/mpi/gcc/openmpi-1.4.3/bin/mpirun -np 2 --mca btl_base_verbose 50 --mca btl_openib_verbose 1 -host cluster1,cluster2 /usr/mpi/gcc/openmpi-1.4.3/tests/osu_benchmarks-3.1.1/osu_latency then I get these errors: <snip> # OSU MPI Latency Test v3.1.1 # Size Latency (us) [cluster1:64027] *** Process received signal *** [cluster1:64027] Signal: Bus error (10) [cluster1:64027] Signal code: Invalid address alignment (1) [cluster1:64027] Failing at address: 0xaa9053 [cluster1:64027] [ 0] /usr/mpi/gcc/openmpi-1.4.3/lib64/openmpi/mca_pml_ob1.so(+0x62f0) [0xfffff8010209e2f0] [cluster1:64027] [ 1] /usr/mpi/gcc/openmpi-1.4.3/lib64/openmpi/mca_coll_tuned.so(+0x2904) [0xfffff801031ce904] [cluster1:64027] [ 2] /usr/mpi/gcc/openmpi-1.4.3/lib64/openmpi/mca_coll_tuned.so(+0xb498) [0xfffff801031d7498] [cluster1:64027] [ 3] /usr/mpi/gcc/openmpi-1.4.3/lib64/libmpi.so.0(MPI_Barrier+0xbc) [0xfffff8010005a97c] [cluster1:64027] [ 4] /usr/mpi/gcc/openmpi-1.4.3/tests/osu_benchmarks-3.1.1/osu_latency(main+0x2b0) [0x100f34] [cluster1:64027] [ 5] /lib64/libc.so.6(__libc_start_main+0x100) [0xfffff80100ac1240] [cluster1:64027] [ 6] /usr/mpi/gcc/openmpi-1.4.3/tests/osu_benchmarks-3.1.1/osu_latency(_start+0x2c) [0x100bac] [cluster1:64027] *** End of error message *** [cluster2:02759] *** Process received signal *** [cluster2:02759] Signal: Bus error (10) [cluster2:02759] Signal code: Invalid address alignment (1) [cluster2:02759] Failing at address: 0xaa9053 [cluster2:02759] [ 0] /usr/mpi/gcc/openmpi-1.4.3/lib64/openmpi/mca_pml_ob1.so(+0x62f0) [0xfffff8010209e2f0] [cluster2:02759] [ 1] /usr/mpi/gcc/openmpi-1.4.3/lib64/openmpi/mca_coll_tuned.so(+0x2904) [0xfffff801031ce904] [cluster2:02759] [ 2] /usr/mpi/gcc/openmpi-1.4.3/lib64/openmpi/mca_coll_tuned.so(+0xb498) [0xfffff801031d7498] [cluster2:02759] [ 3] /usr/mpi/gcc/openmpi-1.4.3/lib64/libmpi.so.0(MPI_Barrier+0xbc) [0xfffff8010005a97c] [cluster2:02759] [ 4] /usr/mpi/gcc/openmpi-1.4.3/tests/osu_benchmarks-3.1.1/osu_latency(main+0x2b0) [0x100f34] [cluster2:02759] [ 5] /lib64/libc.so.6(__libc_start_main+0x100) [0xfffff80100ac1240] [cluster2:02759] [ 6] /usr/mpi/gcc/openmpi-1.4.3/tests/osu_benchmarks-3.1.1/osu_latency(_start+0x2c) [0x100bac] [cluster2:02759] *** End of error message *** --- The whole output can be found here: http://net.razik.de/linux/T5120/openmpi-1.4.3-verbose.txt That's my 'ompi_info --param all all' output: http://net.razik.de/linux/T5120/openmpi-1.4.3_param_all_all.txt Same error with OFED-1.5.4-rc4 and also the same with openmpi-1.4.4.
