Agenda

Review 1.10

• Milestones: https://github.com/open-mpi/ompi-release/milestones/v1.10.2
• Looks good in MTT world.
  • Jeff's cluster had some timeouts on 10.10 network (no route to house), maybe cluster config. Ignore for now. Weird that no route should FAIL, not timeout. TCP BTL. Maybe multirail issue. inf. loop rather than fail.
  • Don't block 1.10 release since probably not common use case.
• Paul found some issues.
• NAG fortran support configuree isn't right.
  • NOT a regression (in 1.8). Do we care if this is a blocker?
• mpirun is hanging after good run. Only in SLES. Also Cray (uses SLES).
  • proc is defunct / zombied.
  • IO Forwarding file descriptors may not be getting HANGUP.
  • Not a Regression, 1.10, 2.0, master. ORTED in event library. Pretty serious, but hoping it's just SLES issue.
    • Set state machine verbosity to 5.
    • Nathan will look at SLES 11 and SLES 12 (Different kernels even, very different)
    • Try to find if it's sigchild or file descriptor
  • Hold 1.10.2 release until Nathan runs tests today.
