Topics to discuss

• Review action items from Jan meeting
• PMIx integration and API extension for PMIx v2.0
• "Instant On" status and planning
  • Async add procs
  • Direct modex support
  • Distributed mapping
• Thread multiple support status
• Git / github usage. How's it going? What's going well / not well? What can we improve on?
  • One idea: should everything on master be a pull request (just to get smoke testing on a variety of systems)? No code czar -- anyone can still push the "merge" button.
• ORTE process name change - replace jobid with namespace
• MPI 3.1 - are we ready?
• Can we add new environment variable CUDA_AWARE_SUPPORT and also create info key on MPI_COMM_WORLD for runtime detection?
