1. 7/24/2008Alex Howard, Profiling PreCompound/De-excitation mini workshop, CERN 1 Profiling Initial timing studies – Test30, p(22MeV)+Al Ref-06: 1960s for 500000 events Tag10: 4240s for 500000 events (also initialisation time is slightly longer – 0.5s)

2. 7/24/2008Alex Howard, Profiling PreCompound/De-excitation mini workshop, CERN 2 kCachegrind output Two runs – 10k and 100k events (factors out initialistion) Function cost is displayed for G4 running with valgrind and debug mode (so not compiler optimised) A selection of the most expensive functions is displayed for –Tag10 –Ref06
