We have found that recent MPI jobs using openmpi/1.10-hpcx and openmpi/2.0-hpcx on Owens may complete or hang until the job is killed, but receive segmentation fault. Some applications might be affected (if you run these applications with openmpi mentioned above): orca, openfoam and lammps. OSC users can use other compatible versions, e.g. openmpi/1.10.7-hpcx and openmpi/2.1.6-hpcx. Please check available version from the software page.
