Agenda

Review 1.10

• Milestones: https://github.com/open-mpi/ompi-release/milestones/v1.10.3
  • PR 1097 - for 1.10 may be mute.
  • PSM2 issue short version. PSM2 API - uses a fixed UUID - so all jobs across cluster use same UUID (bad)
  • Jeff will check 1.10.3 lib versions. Ralph already updated for 1.10.3, but jeff will check

Review 2.0.x

• Wiki: https://github.com/open-mpi/ompi/wiki/Releasev20
• Blocker Issues: https://github.com/open-mpi/ompi/issues?utf8=%E2%9C%93&q=is%3Aopen+milestone%3Av2.0.0+label%3Ablocker *
• Milestones: https://github.com/open-mpi/ompi-release/milestones/v2.0.0 *

Review Master MTT testing (https://mtt.open-mpi.org/)

• Widespread failure of mpool / rcache failure on usNIC last night.
• Ralph is seeing a bunch of attribute failures on 1.10.
  • Jeff is passing in BTL parameters that limits him to a shared memory component, but it's going across nodes. So the attribute thinks it's failing, because some of them can't communicate.
  • 1.10 is hanging if it doesn't get enough slots.
