Agenda

Review 1.10

• Milestones: https://github.com/open-mpi/ompi-release/milestones/v1.10.2
• Need to verify that library versions are still correct.
• Cisco Weekend MTT tests didn't look good.
  • Build failure also.
  • usNIC unable to connect. Maybe a cluster issue.
  • Autogen --force didn't bring to 1.10, should remove from Cisco MTT.
  • Ralph will try to replicate MPI_Abort. Abort test itself.
  • 1.10 C Strided mutex lock issue. Nathan not surprised if it might be a bug. 1 fail. specific build config.
    • enable memchecker build could be affecting timing. Nathan will take a look... should be simple.
  • Jeff will look at MTT things after call.
  • High CPU utilization on Async progress thread. Ralph will take a look. From -GE.
• After all of these issues are resolved / addressed can ship 1.10.2
