Subject: [OMPI devel] 1.7.4rc1 run failure on Solaris 10 / SPARC (not SIGBUS)
From: Paul Hargrove (phhargrove_at_[hidden])

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.
