● Proposed Menus in 2008: One single menu with >160 HLT paths which was supposed to cover a wide luminosity range L = 8.01029 1.01032 cm2s1
● Change of Strategy:❍Decided to reduce number of trigger paths (maintenance, manpower)❍Different menus for 3 reference luminosities:
8.0 10 29 (8E29), 1.0 10 31 (1E31) and 1.0 10 32 cm2s1 (1E32)● Initial version of lean 8E29 and 1E31 menus were presented to all groups
shortly after November 2008 CMS week in order to be reviewed by all● Trigger Reviews:
❍ Thu Dec 11 (CMS week): JetMET❍ Mon Dec 15: Muons❍ Wed Dec 17: Egamma❍ Wed Jan 14: btag/tau/pflow❍ Wed Jan 21: Crosstriggers❍ Wed Feb 4: AlCa/MinBias/Commissioning triggers
● After reviews and following approval process: Trigger Development Group (TMD) started to compile the menus and evaluate the rates

Software & SamplesSoftware & Samples
3 Trigger Menus, C.N.Nguyen CMS Physics Week, 2009 May 13th
● Many new trigger paths not yet implemented in 22X release: Running OpenHLT on Summer08 samples, considered as best choice to give estimates on rates and give fast feedback to groups
● OpenHLT has been validated several times and has been shown that it can consistently reproduce rates made from regular HLT software
● However, some few algorithms cannot be simulated:❍ other estimate approaches applied or planned to Menus & Rates are preliminary!
● Samples:❍ sbQCD (9.9 M events): /MinBias/Summer08_STARTUP_V5_STARTUP_V5_v1/GENSIMRAW ❍ CMSSW_2_2_5❍ STARTUP_V8 GlobalTag❍ DigiToRaw redone
❍8E29:❏ No L1 jet corrections except for flat 0.7 HF correction, also no HLT jet corrections❏ L1 scales optimised for low energies (convertion scheme from ET to GT bit configuration):

Summary:● Change of Trigger Menu Strategy
❍From a single menu with wide luminosity coverage to multiple menus for different reference luminosities
● Preliminary menus & rates for L = 8.0 10 29 (8E29), 1.0 10 31 (1E31) presented● Preliminary rates are within bandwidth limits
❍Though still not all paths can be simulated in OpenHLT❍All trigger paths are currently being checked onebyone ❍New draft versions are being announced regularly
Plans:● Timing needs to be checked● Move to CMSSW 31X to evaluate rates with regular HLT software● Starting 1E32 menu (redo HLT exercise)● Physics performance (ongoing reviews to validate performance of current menus)● 2_2_6_HLT 8E29 menu is currently running in MWGR (first results expected soon)
