Review All Open Blockers
Review v2.0.x Milestones v2.0.4
- put some PRs on branch, but not forcing a new release.
Review v2.x Milestones v2.1.2
- A few PRs coming through.
- Bugfix only mode.
- Launchmond / Alliena attach mode - Issue 3660. This mechanism is part of MPIR,
- regresed from 2.0 to 2.1.
- MPIR attach FIFO - never tested this well.
- It'd be good to have a version of STAT on test.
- Launchmond has integration tests themselves. Problem is it either hangs, or works.
- Ralph will send receipe to devel mailing list.
- We will scope the scale of the fix (should be easier to see what regressed from v2.0 rather than backport something from v3.0
Review v3.0.x Milestones v3.0
- 4509 madvise hook - Jeff and Howard will discuss.
- Now that we hook madvise, we need to be morecareful.
- Nathan hopes his PR 4576 on master would reduce the occurances to 0, but need user to verify.
- may have to invalidate a LARGE region, even though it's mostly valide just because glibc invalideded a small part of it.
- Will test 4576 in master tonight, and then merge into v2.x, v3.0.x and v3.1.x
- Any other blockers for v3.0.1? Need to tag them very soon. Want to release before end of holidays.
Review v3.1.x Milestones v3.1
- v3.1.0 still has Blocker Issue 4509
- Hope it was fixed in PR 4576 in master tonight, to merge in later.
- Dist Graph Create / Tree Create is still segfaulting - but others can't reproduce.
- Blockers:
- madvise
- IMB fails with vader
- update to PMIx v2.1.0
- bugfix - dependency in PMIx, mellanox is working on this.
- PR4606 PGI failure in OMPI pull request, but it passed in PMIx.
- Issue 4465 - rsh launching failures Mellanox is looking at. Not sure if it's v3.0.0, v3.1.x or master only.
Review Master Master Pull Requests
-
Issue 4303 What do we do with Treematch?
- segfaults frequently, so maybe turn it off by default. Component in topo, creates graphs when you create a communicator.
- If you get a reproducer, then update ticket and hand to George.
- Seems to be a memory leak in the OMPI Jenkins
- Working on a solution
- Workaround by turnning off pipeline builds.
Review Master MTT testing
- Brian sent an email earlier this week about News file
- Either we make merging painful for developers, or we create a rather large amount of work for release managers.
- Can automate via Pull Request that ends up in the merge.
- block NEWS: whatever you want NEWS to be.
- With metadata, using Pull Requests, then can change that NEWS block after the fact.
- Would happen at make dist time. Public API calls.
- WebEx Schedule: WebEx Next Tuesday Dec19 (unless 0% chance of getting v3.0.1 out)
- Cancel Dec 26,
- Cancel Jan 2nd
- Jeff will create new WebEx URL for 2018.
- See on list email
- Tentatively: Jan 23-25
- Geoff will send email to devel-core asking if the community wants to push the date back to Feb or March.
- Mellanox, Sandia, Intel
- LANL, Houston, IBM, Fujitsu
- Amazon,
- Cisco, ORNL, UTK, NVIDIA
