- Nathan Hjelm's day job will no longer involve Open MPI, so if you want him to review something, please check with him first.
- Next face to face is San Jose - April 23-April25 @ Cisco -San Jose.
- Jake Hemstad from nVidia has some new use-cases for Open MPI he'd like to discuss
- Should we meet next week during MPI Forum?
- No meeting next week. Geoff will send out email.
Review All Open Blockers
Review v3.0.x Milestones v3.0.3
- Schedule RC maybe later this week.
- Jeff will help Brian out
- Waiting on a vew PR reviews (Brian)
- New update needed.
- Need to merge PR3248.
- Merged in a bunch of changes, and MTT still looks good.
Review v3.1.x Milestones v3.1.0
- Schedule RC maybe later this week.
- Merging PRs this morning
- Merged in a bunch of changes, and MTT still looks good.
- Consider disabling pmix-new-shmem mca param. (see PMIx Issue 1114)
Review v4.0.x Milestones v4.0.1
- Schedule: waiting for Issue6278 fix
- v4.0.1
- Serious issue https://github.com/open-mpi/ompi/issues/6198, but won't hold v4.0.1
- Schedule: Delaying post Summer ***
- Discussion of schedule depends on scope discussion
- if we want to separate Orte out for that? Would be a bit past summer.
- Giles has a prototype of PRTE replacing ORTE
- Want to open up release-manager elections.
- Now that we're delaying, will decide at face2face.
- Is anyone pushing for a Summer of 2019 schedule?
- It seems too aggressive to everyone on the call
- One driver was to remove things to break ABI.
- Not a bad idea to DO v5.0, but summer timing is bad.
- Delaying would allow for switching to PRTE.
- PMIx Tools support
- Now the possibility of v4.1 from master is a possibility
- If we instead do a v4.1, some things we'd need fixed on master.
- will discuss more at face to face.
- Good Job Ralph fixed the 100% Cisco MTT fail.
- Cisco now has 70,000+ good runs. Still some static build issues.
- Take a look at Gile's PRTE work. He may have done SOME of that. He should have done that all in PRTE layer, maybe just some MPI layer work remains.
- PR6339 - he's closed, and re-opened a new branch to look at.
- Howard reviewed PR6339, and likes everything that Giles did, so abandoned his branch
- IBM still has 10% failure rate and build issue. Please fix.
- Jake from nVidia discussed their intereste in a Use-case using
- https://github.com/dask/dask-mpi/issues/25
- Is there a way to setup
- Two main approaches:
- convert existing Dask processes into MPI processes
- dynamicly create MPI processes with MPI Dynamic tasking.
- Sounds like targeting PMIx directly might not be best path.
- MPI_Sessions is designed to solve this.
- Other things in PMIx that might want to access.
- PMIx will be getting Python bindings about 80% done, summer?
- Next week - March 4th is next MPI Forum (then June)
- No Open MPI weekly web-ex next week.
- We have a new open-mpi SLACK channel for Open MPI developers.
- Not for users, just developers...
- email Jeff If you're interested in being added.
- how do we get more participation, and make MTT more meaningful?
