Starsim timing tests
Abstract: A few timing tests running starsim under different configurations.
Run starsim with default EMC_10keV trackinig cuts and high EMC_1MeV tracking cuts:
Pythia 6.4.22
QCD 2 --> 2 processes with ckin(3) = 5 GeV
MACRO timeit CUT=EMC_10keV GDROP ALL DETP GEOM y2009a [CUT] gexec $STAR_LIB/geometry.so gexec $STAR_LIB/Pythia6_4_22.so gexec $STAR_LIB/bpythia.so TUNE 100 CKIN 3=5.0 MSEL 1 TRIG 50 ** 50 events RETURN
Results:
EMC_10keV: 5.28 s / event or rate = 0.1724 Hz
EMC_1MeV: 3.60 s / event or rate = 0.2778 Hz
Conclusion:
1 MeV cuts are about 60% faster than default for "typical" pp running.
