HLT Algorithm Integration Workshop Summary and Future Plan

1. 1 HLT Algorithm Integration Workshop Summary and Future Plan

2. 2 Well attended (~10 participants) Tutorial of running athenaMT with the calorimeter slice (egamma, tau, jet) by Xin Wu Tutorial of running athenaPT with the calorimeter slice (egamma) by Imma Riu Tutorial of running athenaMT with online monitoring histograms with the calorimeter slice (egamma) by Till Eifert Demonstration of creating and running an online partition by Andre dos Anjos and Per Werner Demonstration of running an online EF-monitoring partition by Serge�Sushkov Feedbacks received are generally good Could be repeated in the future, probably with some new features: With release 12? With database configuration? Combined with tutorials on running online partitions? Shifters for Large Scale Test Offsite testbeds for algorithm integration

3. 3 Attended mainly by algorithm developers (~10 people) Some consensus reached on algorithm online integration HLT algorithms developed in the offline framework have made great progresses and time is ripe for integration tests First step of integration is best organized as trigger slices Egamma, muon, tau, jet/etmiss, B-physics, � Each slice has 1-2 people responsible for online integration People identified Egamma: Xin Wu, Imma Riu Muon: Alessandro Di Mattia, Diana Scannicchio Tau: Pilar Casado Jet/Etmiss: Ignacio Aracena, John Idarraga Need to have person(s) to serve as centralized interface to the HLT integration team and to coordinate slice integration Follow HLT releases, provide examples, follow up feedbacks and requests, produce combined jo�s and BS files, � People identified (for the next few months �) Imma Riu, Xin Wu

4. 4 HLT algorithms developed in the offline framework Read MC pool RDO files and use transient BS Run together with Reconstruction Well suited for trigger performance studies (efficiency/rate, physics) Steps tried in algorithm online integration with 10.0.6 Setup a slice running in the offline framework Derive a minimal jobOption to run with BS input Reduce to minimum couplings to high level jo files (flags) for offline reconstruction and offline trigger studies Test the jo with athenaMT Compatibility mode, single thread, multithread Combine slices to a single jo Produce BS input file including different L1 RoI type Test the combined jo with athenaMT Pass the slice and combined jo to HLT integration team Tried with muon (Mufast+InDet) and egamma (T2Calo+InDet) Also try standalone athenaPT and EF integration

5. 5 Follow the similar strategy as 10.0.6 Ask people from slices to setup slice integration Use the tutorial from the workshop as starting point Produce a jo of a full slice (LVL2+EF) with BS input Produce a BS input file from CSC production Test it with athenaMT and athenaPT If possible include LVL2 algorithm monitoring histogram Same jo should work both online and offline Default is full slice offline Use flag doMT, doPT, doLVL2Only, doEFOnly Keep an working example in 11.0.6 nightlies Egamma slice will be ready in a few of days Will run in HLT nightly test Other slices are in good progress and will be added when ready Aim for egamma, muon, tau and jet slice integration Also try to have combined integrations Eg: egamma+muon, egamma+tau+jet, � Encourage algorithm developers to participate in pre-series test

6. 6 HLT algorithm integration was well treated during the workshop Tutorial well appreciated Parallel discussion reached consensus on integration strategy A team of people from the algorithm slices are working for integration with 11.0.6 First to integrate some individual slices Egamma: almost ready Jiri Masik integrated the calo slice (T2Calo+TrigCaloRec) of 11.0.5 into HLT image in short time after the release was out Muon: LVL2 almost ready, EF in good progress Tau and Jet: LVL2 almost ready, EF starting Then try combining slices If the current approach works will try integration with release 12 Ensure strong participation of algorithm developers in the next Large Scale Test Also in P1 pre-series tests
