  1. Performance Measurement of LArTest Tao Lin IHEP 26th Sept. 2017

  2. Dev Env • OS: Scientific Linux 6.5, GCC: 4.9.4, Binutils: 2.28 • Geant4 10.3.p01. Two versions: • Default version • Modified version: with properties table’s modification • Testbeds • Jnws008 (32 cores, E5-4620 v2, 128GB) • Jnws054 (24 cores, E5-2680 v3, 64GB) • MC: hanswenzel/lArTest, V1.0 • COMMAND: lArTesttinylArBox.gdmle-_tiny_noio.in -t 1

  3. Notes • No Optical Photons by default! Need to enable stack photon options. • /process/optical/defaults/scintillation/setStackPhotonstrue • Instead of using muon, using low energy electrons. • /gun/particle e- • /gun/energy 4 MeV • Turn off I/O • Analysis root file • /testConfig/WriteHits false • /testConfig/DoAnalysis false • Reduce G4cout • // G4RunManager::GetRunManager()->SetPrintProgress(1); • /process/optical/verbose 0

  4. Results • Using Default Geant4 • Using Modified Geant4 Time Speedup Performance Problem
