Testing with Solaris 10 on SPARC, I was expecting to encounter the bus error reported previously by Siegman Gross. Instead I see the following hwloc-related abort:
$ env PATH=/home/hargrove/OMPI/openmpi-1.7.4rc1-solaris10-sparcT2-ss12u3-v9/INST/bin:$PATH LD_LIBRARY_PATH_64=/home/hargrove/OMPI/openmpi-1.7.4rc1-solaris10-sparcT2-ss12u3-v9/INST/lib:$LD_LIBRARY_PATH_64 OMPI_MCA_shmem_mmap_enable_nfs_warning=0 /home/hargrove/OMPI/openmpi-1.7.4rc1-solaris10-sparcT2-ss12u3-v9/INST/bin/mpirun -mca btl sm,self -np 2 examples/ring_c -------------------------------------------------------------------------- Open MPI tried to bind a new process, but something went wrong. The process was killed without launching the target application. Your job will now abort. Local host: niagara1 Application name: examples/ring_c Error message: hwloc indicates cpu binding cannot be enforced Location: /home/hargrove/OMPI/openmpi-1.7.4rc1-solaris10-sparcT2-ss12u3-v9/openmpi-1.7.4rc1/orte/mca/odls/default/odls_default_module.c:478 -------------------------------------------------------------------------- 2 total processes failed to start I am assuming I just need some magic pixie dust to disable cpu binding. I'd appreciate some corresponding instructions. However, if this is NOT an expected/desired/known behavior please let me know what I can/should do to help determine the root cause. -Paul -- Paul H.
