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.

v4_10_4 EMZ

Started Mar 21, 2018, proposed update to v4_10_4 EMZ from v4_10_2_p03e.

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

# the above is to see the ranges printed
physics.producers.g4run.physics.modifyEMOption4 : true
physics.producers.g4run.physics.physicsListName : "ShieldingM_EMZ"

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

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

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

v4_10_4

Started Mar 1, 2018, proposed update to v4_10_4 from v4_10_2_p03e. Effort paused on 3/21/18 - now working on v4_10_4 EMZ

How to trigger Mu2e specific electromagnetic option4 (_EMZ) with modified msc model transition energy (committed 3/16/18), off by default, on where noted. 

physics.producers.g4run.debug.diagLevel         : 1
# the above is to see the ranges printed
physics.producers.g4run.physics.modifyEMOption4 : true
physics.producers.g4run.physics.physicsListName : "ShieldingM_EMZ"

How to change the stepper to the new one requiring fewer field evaluations: 

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

clhep 2.4.0.0 (not used yet) 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%)
