Introduction

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.

Note on MT build

4/4/18

  • The geant 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.


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.

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

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

to 

setup -B geant4 v4_10_4_p02 -q${MU2E_UPS_QUALIFIERS}${MU2E_G4_GRAPHICS_QUALIFIER}

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. 

physics.producers.g4run.physics.stepper : "G4DormandPrince745"

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)


Results from tests, 1M conversion electrons, 300K beam stage1

Sample CPU (s) MEM (GB) file size (MB)
old beam 9351 1.611 6.290
new beam 8483 (-9%) 1.715 (+6%) 6.397(+2%)
old CE 6795 1.742 918.396
new CE 6180 (-9%) 1.804 (+4%) 909.979(-1%)

Yuri neutron production rates and transport
4/19/18 Yuri CRV deadtime I don’t think new version will make any impact on the CRV rates.
4/16/18 Dave (LBL) conversion electron efficiency Efficiency and quality are slightly degraded
4/14/18 Jim/Yaqian STM efficiency lead flourescence and brem bkg checked
4/14/18 Jim/Yaqian STM background lead flourescence and brem bkg checked
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.
Ralf cosmic background
Bob p-bar background
4/10/18 Andrei beam electron background Skip. May be feasible in the future.
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.

How to trigger Mu2e specific electromagnetic option4 (_EMZ) with modified msc model transition energy (committed 3/16/18)

How to change the stepper to the new one requiring fewer field evaluations (off, except where noted):

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