• June 29 trunk branches to 1.7.0
• Aug 15th 1.7.0 feature complete
• Oct 1 release of 1.7.0 (tentative)

Branch point gating

• ORTE State Machine (Complete)
• uGNI / Cray XE support
• Non-blocking Collectives
  • Fortran bindings
  • Implementation of good ones
  • bring in libnbc for basic
• grdma mpool
• June 22nd goal for all gating to be in
• June 29th goal for branching

Topics of Focus

• MPI-2.2 Compliance
• MPI-3 Compliance
• State-machine based ORTE
• Thread safety (progress and MPI)

• Turn ORTE progress thread on by default for now, see what breaks over next few weeks. If all is okay, then remove option

• BTL Resiliance
  • Failover (PML issue?)
  • Recovery from resource exhaustion
  • Flow control
• Process failure notification

Testing

• What do we want to test?
  • Need to come up with options list
  • Who can write tests?

Workshop

• Open MPI 1.7 release item
• PML code-forking issue
