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.
Geant4 package switches supported:
- mt - slf7 prof/debug with mt linked, and OGL libraries, OGL not linked by default
- non-mt, with qt, slf7 prof/debug only for viewing geometry
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_5_p01a
Propose to move to this version 8/21/19. The dependencies should be the same as already on the head.

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}

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.
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)

| 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. |

| 4/10/18 | 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.
