@cz4rs : Issue #178 @ checkpoint: added serialization skip for sanitizer, PR #179 was merged, issue closed Issue #1258 @ vt: fields missed during serialization / footprinting: updated and marked skipped variables explicitly Issue #12 @ serialization-sanitizer: converted runtime sanitizer into a clang plugin, working on integration with checkpoint and vt @JacobDomagala:

883 Looks like it's ready to be merged

1215 Close to being done, will need to do some testing of new docker image

1216 Also is almost done (will have to move the action repository to DARMA-tasking, and also the graph requires few tweaks)

1266 PR is open for review

Both #1272 and #1260 are on my TODO list @jstrzebonski : vt #1239 (Explore updating or deleting old comments with errors/warnings) is finally done. No more warnings-errors spam in PR thread. One remark - if the compilation itself was successful, but other pipeline's steps failed (like tests), the comment saying that build for given commit was successful will still be posted. If that's somehow confusing, the message could be change to something better - I'm open for propositions if that's the case. I got back to spack-package #1 (Test current package and expand parameters to building VT/checkpoint) @PhilMiller : working on Kokkos::parallel_for changes for CUDA streams; ULTs issues @nmm0 : done with paper, resuming work with bvh optimization and load balancing, working on NimbleSM paper @nlslatt : Posted PR #1273: fixes a failed assert when empire runs with tracing enabled. Posted PR #1274: makes building the release branch easy like develop. Posted PR #1277: makes stats files generated by the release branch usable (in my case, for testing load balancers). Issue #1279: I'm removing bugs from GossipLB, as discussed last week. Issue #1265: I'm polishing stats-reading driver that Jonathan created. LBAF issue #72: I found a bug in LBAF’s CMF that led to new ideas about getting better imbalance. Bus error: I have not yet identified the cause of bus error during LB seen on Stria for empire+vt runs using multiple LBs.

Description Weekly Meeting

Agenda:

Minutes

@cz4rs : My update: vt #1258: add fields omitted during serialization - fixed vt #1229: enable debug prints and assertions in release builds - prints and assertions are now on by default, use vt_production_build_enabled flag to disable them at compile time; I am fixing minor issues and waiting for more feedback; TestTermDepSendChain.test_term_dep_send_chain_merge is failing regularly (only on macosx build) - investigating serialization-sanitizer #12: convert sanitizer into a clang plugin - not much time spent here, still working on integration with vt and CI; it seems that it's not possible to edit and compile files in a single run (sticking with PartialSpecializationGenerator for now) Misc:

1229 removes a couple of obsolete scripts, vt-auto-build repository can be removed (archived?) now (admin rights required)

1229 is supposed to both change the mechanism and categorize existing prints (terse, normal, verbose levels); this can be done in separate PRs if debug prints in release are needed faster

@JacobDomagala: Pending PRs

1215 (Using prebuilt docker image for pushdockerimage.yml) PR waiting for reviews

1216 (graph build times of pushdockerimage.yml) Is open for reviews - mostly waiting for graph-repo PR to be merged

1293 - remove dead code in vrt-collection

WIP:

1272 - Use runSchedulerWhile instead of runScheduler when applicable -> I'm close to creating PR for this one

1260 - Not much to update on this one, hopefully will progress on it this week

Done

1266 - Use checkpoint reconstruct for migrated vrt-collection elems

1286 - Fix issues after merging #883

@jstrzebonski : spack-package #1 (Test current package and expand parameters to building VT/checkpoint) - is done. I reworked the package a bit: vt's configuration parameters can be used for build packages names are unified simple sanity checks are added vt #1290 (Add Azure pipeline to test vt spack package) - That's almost done. I'm currently finishing testing build script locally on my machine. @PhilMiller : Little bits of code review, otherwise focused on Kokkos/Cuda/EMPIRE stuff @nmm0 : My update: done with paper, resuming work with bvh optimization and load balancing, working on NimbleSM paper @nlslatt : My update: I made the LB testing/tuning driver a lot more powerful. It only reads release stats files right now but I will add support for develop, probably after we change the stats format soon. I also added asynchronous informs to GossipLB and made an option to switch between that and the synchronous informs. I'm hoping to play with these two branches together tomorrow. I'm getting close to posting PRs.

@jstrzebonski : I'm working on two things at the moment: vt #1290 (Add Azure pipeline to test vt spack package) - I prepared Azure pipeline based on azure-gcc-10-ubuntu-openmpi but vt cannot be compiled on it because of the resources limit: /usr/bin/ld: final link failed: No space left on device Here's a link to logs: https://dev.azure.com/DARMA-tasking/DARMA/_build/results?buildId=8850&view=logs&j=3[…]-5a92-293e-d53cefc8c4b3&t=28db5144-7e5d-5c90-2820-8676d630d9d2 vt #1291 (Build warnings/errors forwarded don't include test status) - After short experiments this seems to be easy to do. I don't have working solution yet, but I'm close to make it. @PhilMiller : Merged a change to vt’s cmake in EMPIRE https://cee-gitlab.sandia.gov/EM-Plasma/EMPIRE/-/merge_requests/1482 - this should be incorporated in the vt repository as well, especially before any new stable release Reduced Intel ICE seen with rehash usage and reported I wrote up and shared notes on a meaningful object ordering for refinement-based LB strategies like GossipLB On that note, it may be worth considering alternatives that accept larger candidate objects earlier if sufficiently underloaded processes are available to send them to - the marginal object threshold is the smallest object size that will necessarily be migrated to achieve non-overload, but there’s nothing actually saying we can’t go bigger instead, just the heuristic that it will be harder to find spots for bigger objects Work continues on EMPIRE adaptation for CUDA streams @nmm0 : Working with Jonathan on debugging LB migration crash Adding a compile-time toggle in my code to switch on and off insertable collections to narrow down bug @nlslatt : 'm still focused on improving GossipLB (issue 1279). Added options for considering objects to migrate in arbitrary (ordering=0), ID (ordering=1), or marginal (ordering=2) order Added deterministic mode (LB arg deterministic=1), which is not compatible with arbitrary ordering Added different CMF options: original, which excludes recently overloaded processors (cmf=0), keep recently overloaded and normalize by greater of max and avg load (cmf=1), and keep recently overloaded and normalize by own load (cmf=2) Found a bug in GossipLB that made it difficult to iteratively refine the load balance Noticed that post-migration object load statistics race with object migration Started running some 400 rank experiments on Stria to exercise new options GossipLB was only 1.5% slower on bdot vt-capable work (which includes extra reductions for debugging) than HierarchicalLB on 400 rank run

@cz4rs : vt #1229 - debug prints and assertions in release builds - PR #1288 merged, issue closed vt #1317 - memory leak (asan) - attempted bisect, requires discussion (how should we handle this?) vt #1006 - GroupCollective bug - created a testcase with a simple delay to reproduce the bug, could something akin to CollectionManager::bufferOpOrExecute be used to fix this? @JacobDomagala: Pending PRs: checkpoint - 185 A quick PR to checkpoint with build badges added to README VT - 1272 Remove vt::runScheduler and use runSchedulerWhile instead (where applicable) VT - 1328 Add helper macros to skip running tests based on current number of nodes used. Change CMake to also run tests on single node, and disable the tests that shouldn't run on fewer than 2 ranks Almost ready to review: VT - 1297 Increase the number of nodes for our pipelines (After VT - 1328 gets merged, this should be ready for review) WIP: VT - 1260 Sending a message to a functor with the ActiveMessenger requires the message type. Nothing much for this one, I'm looking whether it's possible to have it working without going back to using MsgPtr instead of MsgPtrThief @jstrzebonski : I'm working on: vt #1320 - Put a direct link to Azure builds in PR comment Done: vt #1318 - Silence nvcc builds warning vt #1291 - Build warnings/errors forwarded don't include test status vt #1323 - Don't report test status if compilation failed @PhilMiller : I’m working on wiring EMPIRE up to the new AsyncOpCUDA and ULT infrastructure Porting Charm++ DistributedLB (the inspiration of our GossipLB) @nmm0 : Running LB runs with BVH -- GreedyLB run failed to complete Currently re-running two runs with HierarchicalLB that scales better @nlslatt : I've been comparing GossipLB with full information to GossipLB with partial information, finding that partial information still does very well. I also found and fixed a bug in GossipLB that was causing a failed assertion or segfault when only one underloaded rank was known. I'm waiting on a Trilinos PR merge and rebuild on Stria before running ZoltanLB experiments for comparison.

So, I’ll be scarce this coming week. My work: vt#413 Reviewing change to provide support for suspendable threaded execution of handlers, including refactoring to improve context access Discussions on load balancing improvements @nmm0 : Update: Mostly contact work, ran several runs with load balancer current results show on some problems very large performance improvements (~6x) with load balancer TODOS: run tests without insertable collections and see if there is any difference. Finish work on patch caching on the application side @nlslatt : My update: Found and fixed a bug that allowed receiving messages about underloaded processors too early within GossipLB, but fix interacts badly with the way empire calls the load balancer. Added an option to redefine the terms underloaded and overloaded based on long-pole object sizes (that exceed the processor-average load), but haven’t been able to experiment with it yet due to the above issue. Started experimenting with ZoltanLB.

Agenda:

Minutes:

@lifflander is on an interview panel today.

@nmm0:

• We implemented a fix for the epoch bug problem (https://github.com/DARMA-tasking/vt/pull/1448) – greater than eager threshold • This fixed an issue with some bvh test cases. Also fixed the bug with LB! So that is really good news • Discussed in the meeting that Nic’s not sure if all send cases are being tested yet, so will put in another issue for increased test coverage (#1449)

@JacobDomagala:

• vt - 1424 - throw on vtAbort (and enable this option on our pipelines) -> Merged • vt - 1448 - bug with serialized messaged on self send -> Added test that reproduces the issue • vt - 1440 - label epochs created by vt -> Should be ready to merge i think • vt - 1438 - add perf tests to CI -> Added initial test harness with helpful macros (somewhat similar to how gtest works) and helper timers. Currently I'm working on generating meaningful output (both ASCII and file)

@jstrzebonski:

• Done: DARMA-tasking/checkpoint#203 - I'm still waiting for a review here. • In progress: DARMA-tasking/checkpoint#209 - recursive validation of memory usage during serialization. • Discussed in the meeting that the nvcc pipeline is failing (memory limitations?). Maybe can split up the test that fails to compile

@MikolajZuzek:

• vt #1344: capture message size in MsgSharedPtr: PR #1426 ready for review. • Discussed in the meeting and decided not to put the serialized size into a new message pointer because it’s a fundamentally different quantity. Will either do the sizing within makeTraceCreationSend or just pass it as before.

@nlslatt:

• Still need reviews on PR #1422 • We submitted the LB paper (copy on the Slack load balancing channel) • Also started looking into how I might put the core of my LB testing driver into vt src to serve dual purposes, for automated testing of LBs and for running manually to tune an existing LB for a given problem type or to develop a new LB

@PhilMiller:

• My focus has been EMPIRE stuff, and I was away the latter part of last week. I reviewed the paper draft, and some PRs, but that’s about it

@nmm0: My update: Finally got a lead on the BVH bug. There is a reduction at the beginning of the iteration that seems to be incomplete after load balancing. I'm investigating the circumstances that it's happening under. Some elements of the reduction have been migrated to the same node but I need to double check whether the error hits the first time they get migrated
