Tried tonight's master tarball on Solaris 11.2 on x86-64 with the Studio Compilers (default ILP32 output) and saw the following result
$ mpirun -mca btl sm,self -np 2 examples/ring_c' Error opening /devices/pci@0,0:reg: Permission denied [pcp-d-4:00492] PMIX ERROR: ERROR in file /export/home/phargrov/OMPI/openmpi-master-solaris11-x86-ss12u3/openmpi-dev-2559-g567c9e3/opal/mca/pmix/pmix1xx/pmix/src/client/pmix_client.c at line 181 [pcp-d-4:00491] PMIX ERROR: UNREACHABLE in file /export/home/phargrov/OMPI/openmpi-master-solaris11-x86-ss12u3/openmpi-dev-2559-g567c9e3/opal/mca/pmix/pmix1xx/pmix/src/server/pmix_server_listener.c at line 463 I don't know if the Permission denied error is related to the subsequent PMIX errors, but any message that says "UNREACHABLE" is clearly worth reporting. -Paul -- Paul H.
