ATLFAST CORRECTORS VERSION 15.6.1.2 FOR 10TEV

Timing Study

A timing Study for Atlfast and AtlfastC was carried out in Version 14.5.0 and Version 15.6.1.2. The samples used in this study where ttbar and Z->ee EVGEN samples. The EVGEN datasets where then put into POOLtoAtlfasttoAOD.py job option that produces an Atlfast AOD. With the AOD we create a corrected AOD using AtlfastC_AODtoAOD.py job option, resulting in an AOD with applied efficiencies to replicate the full simulation AODs.

It must also be noted that we can use the PythiatoAtlfasttoAOD.py job option to produce an Atlfast AOD.

Running POOLtoAtlfasttoAOD.py

I will now discuss the steps that where taken to produce an Atlfast AOD (I have included a Logfile below).

Changes to POOLtoAtlfasttoAOD.py

  • Input dataset to Atlfast_ReadPOOLFile.py, which is located in POOLtoAtlfasttoAOD.py (need to get_file Atlfast_ReadPOOLFile.py)

# Use auditors
theApp.Dlls += [ "GaudiAud" ]
#
# write out a summary of the time spent
# write out a short message upon entering or leaving each algorithm
#
theAuditorSvc.Auditors  += [ "NameAuditor" ]
ChronoStatSvc = Service ( "ChronoStatSvc")
#ChronoStatSvc.NumberOfSkippedEventsForMemStat = 50
theAuditorSvc.Auditors  += [ "MemStatAuditor" ]
MemStatAuditor = theAuditorSvc.auditor( "MemStatAuditor" )
theApp.AuditAlgorithms=True 
MemStatAuditor.OutputLevel = INFO
#theApp.AuditServices=True

Running AtlfastC_AODtoAOD.py

I will now discuss the steps that where taken to produce an AtlfastC AOD (I have included a Logfile below).
