DQM: new DQMFileSaver #28588

schneiml · 2019-12-09T19:01:05Z

PR description:

In offline, the legacy TDirectory files for the DQMGUI are written by the DQMFileSaver module. While reading the code and its configurations, it became apparent that this module is not actually used in online or HLT (any more?), even though most of the code is dedicated to these cases. (Online and HLT use DQMServices/FileIO now.)

So, I stripped down this module to prove the hypothesis.

In addition, this PR contains the new TDirectory writing code by @andrius-k, as a new independent class. It is still linked into the DQMStore and can be called as edm::Service<DQMStore>()->save(...). I also updated the Online output modules to use this helper (DQMFileSaverOnline) or contain the writing code (DQMFileSaverPB). Consequently, DQMStore itself does not contain file writing code any more. There is still a huge amount of file reading code, which is largely useless and to be removed next.

PR validation:

This PR needs testing in online DQM (not done yet) and ideally also in HLT (or a solid confirmation that the module is never loaded in HLT). The changes to the ProtoBuf writer need to be tested in the HLT/fastHadd/online DQM chain. None of this is done so far. I'll try to provide a test setup in another PR.

This PR needs testing in Tier0 Express processing, where the runIsComplete logic is used.

The main point of the PR is to test

That only a single mode of this module is used in offline, to be confirmed by the IB tests; (as far as it seems confirmed)
That the new TDirectory writing code works; (confirmed)
Which unit tests depend on behavior removed in this PR. (none, it seems)

[I suspect some tests to fail (assuming these tests are run in the PR tests, not sure about that), and some flaws in the TDirectory writing code (it does not support QTests yet, for example).] Edit: all fixed.

Using commit 70fc23c from andrius-k:dqm-new-dqmstore-on-CMSSW_11_0_0_pre5. Includes changes to make the coe compile and run with the old DQMStore.

…dule.

It looks like this was never actually used in online DQM or HLT in run2. There are plenty of threading-related code paths, but DQMServices/FileIO seems to have taken over at some point.

I did remember to run code-format, this time!

I am surprised that no tests failed, even though #28407 (comment) indicated that the old whiteRabbit DQM tests run in the PR tests.

The comparison looks much more messy than expected though, we'll need to fix a bunch of things it seems.

Edit: I see

Superfluous quotes on strings
Rounding differences with floats (not sure if we'll be able to resolve these)
The missing QTests (I assume these are the 1000's of missing items)
Edit²: actually the majority of missing items are efficiency flag markers.

I don't see what the DQMHistoSizes comparison is doing here though, I assume it is just confused by something. I don't see 100's of KB of new histograms in the bin-to-bin comparison.

Sam-Harper · 2019-12-16T09:06:50Z

@Martin-Grunewald , thanks, I have alerted FOG and we can see if anybody is around to do a quick hilton test

schneiml · 2019-12-16T09:35:37Z

@Sam-Harper if you get to it, can you provide a sample of the streamDQMHistograms output stream? This is what we need to be able to read on online DQM side, and while I can't reproduce this currently (the files seem to be missing a "streamer" header -- is that because I used the fakeFilterUnitMode or does some DAQ mechanism add that later?), looking at the files themselves would be useful...

as suggested by @Sam-Harper , we are trying to test this PR on a Hilton machine (in my understanding, we would then be able to provide a sample of the streamDQMHistograms output stream), but at the moment we are having issues installing a recent CMSSW release there. I'm still trying, but given the limited availability of people this week, this might get delayed to the new year.

schneiml · 2019-12-17T09:24:11Z

@missirol thanks for the update! I'll try to pull some information out of the DQM online playback system in parallel.

schneiml · 2019-12-20T09:40:34Z

For the record: waiting for changes&validation at HLT.

schneiml · 2020-01-06T09:44:06Z

@missirol ran some tests but there were unrelated problems. Still waiting for HLT validation.

schneiml · 2020-01-13T10:16:12Z

The test by @missirol last week looks ok, so this is good to go. (Sorry, forgot to update this PR in time)

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @silviodonato, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
