[TsosGaussianStateConversions] Require GSF states to be positive definite [12_6_X] #39873

swagata87 · 2022-10-27T13:38:46Z

PR description:

This PR is to solve a crash in prompt-reco that led to a paused job as reported in https://cms-talk.web.cern.ch/t/logic-error-in-reco-job-for-run-360888-dataset-parkingdoublemuonlowmass2/16641, and discussed in #39570.

It was checked, from 12_4_X, that this patch cures the crash in low-pT electron reconstruction.

PR validation:

runTheMatrix.py -l 12434.0 ran fine.

From 12_4_X, it was checked that [Base] and [Base+thisPR] leads to same number of electrons, photons and low-pT electrons to be reconstructed, with same pT spectra. This check was made by running on 200 raw events on this file: /eos/cms/tier0/store/data/Run2022F/EGamma/RAW/v1/000/361/197/00000/76bd97fa-4ad6-4d85-b941-014e3ed27f9c.root

Tagging @francescobrivio as this week's ORM.

Backport of this PR might be necessary.

tested explicitly it fixes the issue reported in the cmsTalk¹ ;
no differences seen in the tests;
the GSF tracking code could use some revision as the criteria of or positive definiteness are not harmonised across different modules (see [TsosGaussianStateConversions] Require GSF states to be positive definite [12_6_X] #39873 (comment)), perhaps the author could open a gitHub issue with the details to be reminded about it;

using the recipe at https://github.com/cms-sw/cmssw/issues/35929#issuecomment-1288800329 ↩

urgent

@cms-sw/reconstruction-l2 please give an high priority to the review of this PR which is then needed to fix crashes in Prompt reconstruction in Tier0

mmusich · 2022-10-28T12:10:49Z

type egamma, tracking

swagata87 · 2022-10-30T11:12:01Z

This fix is useful for HLT also, see #39570 (comment).
I expect the HLT Gsf crashes to go away or happen less frequently after this fix is integrated.

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. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)

Urgent fix for datataking. Once this clears IBs we will merge the backport and cut a new 12_4.

rappoccio · 2022-10-31T12:24:18Z

Backports are in #39903 and #39904

mmusich · 2022-11-04T09:53:49Z

For the record, when the release containing the backport of this PR (#39903) has been tested at tier0, a job that previously was giving an exception, is now having a segfault https://cms-talk.web.cern.ch/t/replay-testing-for-cmssw-12-4-11/17062/4
FYI: @swagata87

swagata87 · 2022-11-04T10:33:26Z

Hello @mmusich

I copied the folder as indicated in the cmsTalk link you shared, /afs/cern.ch/user/c/cmst0/public/PausedJobs/Replay12_4_11/job_1175

From what is reported there, Run: 361239 Event: 453401426 crashed, right?
So I tried to run on that event, by doing this

import FWCore.ParameterSet.Config as cms
from PSet import process
process.source.eventsToProcess = cms.untracked.VEventRange('361239:453401426-361239:453401426')

But it did not crash.
I am in CMSSW_12_4_11 and slc7_amd64_gcc10.

Am I missing something?
Can someone else try to see if the crash is reproducible in some other machine?

mmusich · 2022-11-04T10:38:40Z

Hi Swagata @swagata87,
I am trying to isolate the event that crashes the process as well. Since the process is run multi-threaded, it's not necessarily the last event printed out in the log that caused the crash. One should look which stream underwent the crash.

slava77 · 2022-11-04T13:13:19Z

The t0 logs say

%MSG-e GsfMultiStateUpdator:  GsfTrackProducer:lowPtGsfEleGsfTracks  04-Nov-2022 08:44:48 CET Run: 361239 Event: 453401426
KF updated state 4 is invalid. skipping.
%MSG

for 0-5. How many are tried? Is it a case of everything failing and the code not expecting that?

swagata87 · 2022-11-04T13:34:40Z

From the file from T0, job_1175/job/WMTaskSpace/cmsRun1/cmsRun1-stdout.log; all of 0-5 failed [1].
So it could be that we need another protection somewhere for a scenario where nothing pass. But we could not locate the event yet.. if we can find the exact event that crashed, we would look for a fix. From the log below it looks like Event 453474850 , but this event runs fine from my area.
