  1. Event Filter WGIntroduction CMS Week 26/02/2003 E.Meschi – CERN EP/CMD

  2. Scope • Coordinate activities related to the Event Filter (Software): First meeting • Focus on this year’s milestones on the EvF test stand • Raw data access/format • Configuration/Control/Monitoring of Reconstruction • Subfarm Manager • But also: • HLT Steering code • RC&C management, output streams (production, express, display…) E. Meschi - EvF WG Intro

  3. Tools • Meetings: • to be scheduled on a need basis • But certainly on next CPT (wk. 19, May 8th) • Presentations during the general DAQ weekly meetings (next slot on April 3) • In special cases in RPROM and/or PRS meetings • Listbox distribution list: • mailto:cms-daq-eventfilter@cern.chNEW • Web page: • http://cern.ch/cmsff  (to be updated, volunteers welcome) E. Meschi - EvF WG Intro

  4. Reference docs • DAQ TDR, esp. Ch. 7, 8, 14, 15, 16 • XDAQ Reference Manual and related docs • COBRA/ORCA Online documentation • Web pages for tools in use (Tomcat, Apache, SOAP, JAS, root etc.) • Notes about subdetector data formats, volumes zero suppression and compression algorithms Links to be collected in web page E. Meschi - EvF WG Intro

  5. Where we are • Avoid “special” reconstruction code, extend existing FW: • RawData-to-ORCA path: • Event loop, Raw Data allocation • Replacement ORCA libraries for data access/formatting • Other Online Services • Parameter setting / Configuration: take control of relevant COBRA services (replacement libraries) • Monitoring: interface and format definition for publish/update, prototype implementations AIDA/root E. Meschi - EvF WG Intro

  6. ORCA Raw Data Status † DCC will contain TP and crystal data (see e.g. CMS IN-2002/009), in ORCA, TP in a different data structure E. Meschi - EvF WG Intro

  7. Subfarm Manager E. Meschi - EvF WG Intro

  8. 2003 chart FU+ORCA ALL subdetector reco Prototype components FU/SM, install/mgmt, working demo Test stand complete Results of stress tests Delivered (Dec CMS wk) CPT wk Annual Review Last CMS Wk ‘03 E. Meschi - EvF WG Intro

  9. Subfarm Test Stand BU BU BU FDN FU FU FU FU SM FU FU FU FU MS FCN Run Control FU FU FU FU FS Populate with at least 1 BU and its FUs, 1SM in 2003 E. Meschi - EvF WG Intro

  10. Main goals in 2003 • Exercise one building block of the real subfarm (configuration and system management) • Cold start, code distribution and FU configuration • Test, profiling of HLT steering and reconstruction code (deployment, configuration [trigger table etc.] and monitor) • Demonstrate Subfarm Manager • Combined study of raw data formats, throughput, impact on execution times, of formatting and consistency checks • Stress test: e.g. 1 hr of CMS running • monitors, failure modes, output (repeat in 2004) E. Meschi - EvF WG Intro

  11. Also of interest • Use of parts of EvF in test beam applications • Online monitor, analysis, persistency • Next: Tk TestBeam • Want to see working code: prepare 2 page HowTo to setup an application using existing FU code • Use in Configuration/Monitor of “Tier0” activity • Also, maybe: • Offline analysis of persistent, arbitrary format TB data • Mainly useful for subdetector groups E. Meschi - EvF WG Intro
