Agenda

Review 1.10

• Milestones: https://github.com/open-mpi/ompi-release/milestones/v1.10.3
  • Two pull requests that have not been reviewed:
    • NULL datatypes - Jeff's looking at some oddities to see if we care.
    • distinct namespaces for OSC for pt2pt. - Nathan thinks it's fine.
  • Blocker for "PSM stuff" - Howard reviewed this. Good with this.
  • Jeff owes a library versioning review. already updated for 1.10.3.

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 *
• Discussion:
  • What "gotchas" do we need to communicate to users? I.e., what will people upgrading from v1.8.x/v1.10.x be surprised by?
    • The most obvious one I can think of is mpirun requiring -np when slots are not specified somehow.
    • What else do we need to communicate? It would be nice to avoid the confusion users experienced regarding affinity functionality/options when upgrading from v1.6 -> v1.8 (because we didn't communicate these changes well, IMHO).
    • https://github.com/open-mpi/ompi/wiki/User-Migration-Guide:-1.8.x-and-v1.10.x-to-v2.0.0
    • https://github.com/open-mpi/ompi/wiki/Developer-Migration-Guide:-v1.8.x-and-v1.10.x-to-v2.x
