So much of the understanding of the performance of mu2e depends on simulation studies that a change in geant version could have far-reaching effects.  This page contains a checklist for tests to perform before moving to a new geant.  Typically, some tests would be skipped because the expert decides the effort to validate would not be justified for the low level of risk.

    2637969        35648.2      0.581  mu2e::KalSeeds_KKDeM__ceSimReco.
The KinKal output is large because I've configured that fit persistence to save the full piecewise trajectory, instead of just the
fit parameters at tracker entrance, middle, and exit.  It's a one line configuration change to swap this to out, but I'd rather keep it, as
the full trajectory can provide a much better event display (though it isn't currently used).
      382052        5162.9      0.084  mu2e::KalSeeds_KFFDeM__ceSimReco.
The BTrk size increased because I added payload to KalSeed to support tracker calibrations.

==updates for MDC2020==
2/1/2021, PR's 330 and 332, updated
JobConfig/primary/epilog.fcl
with
physics.producers.g4run.physics.minRangeRegionCuts: { CalorimeterMother : 0.1}
and
physics.producers.g4run.physics.physicsListName:ShieldingM_EMZ
===Remaing questions===
The list below is the set of questions that need to be answered to configure G4 for MDC2020.
In all cases we need to consider: physics fidelity, CPU time, file size
# Should we upgrade to v4.10.7.p01(a)?
# At what energy should we set the break in the EM physics model?
# Which jobs need HP physics lists and which do not?
## Presumably the pure EM Primaries do not need HP.  Anything else?
# Decide on production cuts by region.  The following table is the working proposal
{| class="wikitable"
|+ 
! Value
! Region/Volume
|+
! (mm)
!
|-
|0.700   
|Default
|-
|0.010
| Production Target mother
|-
|0.010
| p-bar absorbers in PS and TS3 (single volumes? mother volume?)
|-
|0.010
| Stopping Target mother
|-
|0.001
| Tracker mother
|-
|0.100
| Calorimeter mother
|}
The default value is chosen to be correct for the CRV plastic; the CRV system does not have any convenient mother volumes.

==v4_10_6_p01==
===issues===
* CRV sign-off needed - is neutron physics reasonable?
* file sizes too large - check PS.fcl, the production version of potSim with filtering
** RLC - checked PS.fcl, the file sizes are equivalent in old and new
* memory sizes too large - check if this is neutron cross section tables
** to test: export G4NEUTRONHPDATA=/cvmfs/mu2e.opensciencegrid.org/artexternals/g4neutron/v4_5/NULL/G4NDL4.5
** RLC confirms making the table change brings CE and POT memory back in line with the "old"
** in KLG's small scale test, the electron/gamma/neutron distributions go back to what was seen with v4_10_5_p01a when the above dataset is used, which is consistent with the memory decrease seen/confirmed by RLC
** 4/15/20 - a tentative discussion to accept the memory increase, and deal with it when the next production needs a fix.  The solution may b e to split the jobs in parts.
===Results===
Proposal to evaluate this version 2/19/20.  This upgrade is to obtain geant features.  It should also fix a geant geometry bug which caused a crash in some particles in the ExtMon.
Comparison done on commit 96105ca37c (head as of 2/20), with the proton generator module name fixed in stoppedMuonsSingleStage.fcl.
Memory and file size results from tests, 250K conversion electrons, 25K POT.  The CPU result are from
repeatedly running old and new version 20min jobs, with various seeds, on the same machine at the same time. "Old" in comparisons is v4_10_5_p01a.

Introduction

So much of the understanding of the performance of mu2e depends on simulation studies that a change in geant4 version could have far-reaching effects. This page contains a checklist for tests to perform before moving to a new geant4. Typically, some tests would be skipped because the expert decides the effort to validate would not be justified for the low level of risk.


Geant4 package switches supported:

  1. mt - slf7 prof/debug with mt linked, and OGL libraries, OGL not linked by default
  2. non-mt, with qt, slf7 prof/debug only for viewing geometry
  3. sometimes the "vg" (vecgeom) versions are installed for future development

Note on MT build

4/4/18

  • The geant4 MT branch code can be compiled against (and run using) a sequential version of G4 without the '-DG4MULTITHREADED' flag in the SConscript file.
  • The MT branch code code can be compiled against an MT version of G4 with the addition of the '-DG4MULTITHREADED' flag in the SConscript file.
  • MT version can be run in 3 modes: (1) in sequential mode, (2) in MT mode using a single thread in which there is a master thread that controls a single worker thread, and (3) in MT mode.


Geant4 v4_11_1_p02

July 12 2023. Testing this newly released geant4 version, a possible fix to the g4 v4_11 bugs seen in the past.

Release notes starting from v11.0:

Geant4 v4_10_7_p04c and v4_11_0_p03

Summary:

  • v4_10_7_p04c is validated and ready to use.
  • v4_11_0_p03 Please do not use this version, or any below v4_11_1_p02, see above for that version validation. It still has non-understood changes which affect the stopped muon rate. This is being investigated. Please note that v4_11_1_p01b is much more configurable than any v4_11_0.

Oct. 25 2022. Testing newly released Geant4 patches.

The KinKal output is large because I've configured that fit persistence to save the full piecewise trajectory, instead of just the
fit parameters at tracker entrance, middle, and exit.  It's a one line configuration change to swap this to out, but I'd rather keep it, as
the full trajectory can provide a much better event display (though it isn't currently used).

The BTrk size increased because I added payload to KalSeed to support tracker calibrations.

updates for MDC2020

2/1/2021, PR's 330 and 332, updated 

JobConfig/primary/epilog.fcl

with 

physics.producers.g4run.physics.minRangeRegionCuts: { CalorimeterMother : 0.1}

and 

physics.producers.g4run.physics.physicsListName:ShieldingM_EMZ


Remaing questions

The list below is the set of questions that need to be answered to configure G4 for MDC2020. In all cases we need to consider: physics fidelity, CPU time, file size

  1. Should we upgrade to v4.10.7.p01(a)?
  2. At what energy should we set the break in the EM physics model?
  3. Which jobs need HP physics lists and which do not?
    1. Presumably the pure EM Primaries do not need HP. Anything else?
  4. Decide on production cuts by region. The following table is the working proposal


Value Region/Volume
(mm)
0.700 Default
0.010 Production Target mother
0.010 p-bar absorbers in PS and TS3 (single volumes? mother volume?)
0.010 Stopping Target mother
0.001 Tracker mother
0.100 Calorimeter mother

The default value is chosen to be correct for the CRV plastic; the CRV system does not have any convenient mother volumes.

v4_10_6_p01

issues

  • CRV sign-off needed - is neutron physics reasonable?
  • file sizes too large - check PS.fcl, the production version of potSim with filtering
    • RLC - checked PS.fcl, the file sizes are equivalent in old and new
  • memory sizes too large - check if this is neutron cross section tables
    • to test: export G4NEUTRONHPDATA=/cvmfs/mu2e.opensciencegrid.org/artexternals/g4neutron/v4_5/NULL/G4NDL4.5
    • RLC confirms making the table change brings CE and POT memory back in line with the "old"
    • in KLG's small scale test, the electron/gamma/neutron distributions go back to what was seen with v4_10_5_p01a when the above dataset is used, which is consistent with the memory decrease seen/confirmed by RLC
    • 4/15/20 - a tentative discussion to accept the memory increase, and deal with it when the next production needs a fix. The solution may b e to split the jobs in parts.

Results

Proposal to evaluate this version 2/19/20. This upgrade is to obtain geant features. It should also fix a geant geometry bug which caused a crash in some particles in the ExtMon.

Comparison done on commit 96105ca37c (head as of 2/20), with the proton generator module name fixed in stoppedMuonsSingleStage.fcl.

v4_10_5_p01

5/14/19 built and installed for testing (including comparing Offline and G4Beamline in target studies). SLF6 for qt was not in the build, only SLF7, so that is installed.

v4_10_4_p03

8/21/19 - this version may be not interacting KL in material as much as it should (Yuri Oksuzian, Krzysztof Genser)

Proposal, started 4/16/19, is to move from v4_10_4_p02a to v4_10_4p03.

Fast checks:

v4_10_4_p02

Proposal, started 9/26/18, is to move from v4_10_4 to v4_10_4_p02. Several bugs are fixed, but nothing that is known to be an issue for mu2e.

Closed out this checklist on 11/8/2018. Actually using v4_10_4_p02a ("a" adds e17 compiler), starting in v7_2_0.

To make a release with this change, edit setup.sh and change this line 

export MU2E_G4_EXTRA_QUALIFIER=':+cl23'
setup -B geant4 v4_10_4 -q${MU2E_UPS_QUALIFIERS}${MU2E_G4_GRAPHICS_QUALIFIER}${MU2E_G4_MT_QUALIFIER}${MU2E_G4_EXTRA_QUALIFIER}

to 

export MU2E_G4_EXTRA_QUALIFIER=
setup -B geant4 v4_10_4_p02 -q${MU2E_UPS_QUALIFIERS}${MU2E_G4_GRAPHICS_QUALIFIER}${MU2E_G4_MT_QUALIFIER}${MU2E_G4_EXTRA_QUALIFIER}




Memory and file size results from tests, 250K conversion electrons, 25K POT. The CPU result are from repeatedly running old and new version 20min jobs, with various seeds, on the same machine at the same time.

v4_10_4

Started Mar 1, 2018, proposed update to v4_10_4 from v4_10_2_p03e. 3/21/18 - effort paused - now working on v4_10_4 EMZ. On 4/4/18, the decision was taken to restart this effort and delay EMZ, which is more complicated. In the comp/soft meeting on 4/18/18, we decided to make this version the new default.

To make a release with this change, edit setup.sh and change this line 

setup -B geant4 v4_10_2_p03e -q${MU2E_UPS_QUALIFIERS}${MU2E_G4_GRAPHICS_QUALIFIER}

to 

setup -B geant4 v4_10_4 -qcl23:${MU2E_UPS_QUALIFIERS}${MU2E_G4_GRAPHICS_QUALIFIER}


How to change the stepper to the new one requiring fewer field evaluations. This is off by default and is not part of this checklist.

clhep 2.4.0.0 (not used in this checklist evaluation) will enable the switch from HepJamesRandom to MixMax random number engine (art sets the default)

4/10/18 Andrei ExtMon efficiency Skip this time (the baseline has not been checked in years). This is feasible to do in the future.
4/10/18 Andrei ExtMon background Skip. A complete study would require very large amount of CPU and effort. Unlikely to be feasible for GEANT upgrade checks. A simpler proxy like e.g. neutron flux in the ExtMon room might be feasible.

4/19/18 Dave (Lou) Pion backgrounds It would require a dedicated run to do a "real" test. However, if I look at muon stops as a proxy for pion stops, then I see nothing here that makes me panic.

v4_10_4 EMZ

Started Mar 21, 2018, proposed update to v4_10_4 EMZ from v4_10_2_p03e. At the code/soft meeting on 4/4/18, we decided to delay moving to EMZ since the very different file sizes caused complications with no obvious benefit. This will be considered at a later date, along with regional minRangeCut's.
