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.
