  1. ALFA - a common concurrency framework  for ALICE and FAIR experiments Mohammad Al-Turany GSI-IT/CERN-PH

  2. ALFA • Common layer for parallel processing. • Common algorithms for data processing. • Common treatment of conditions database. • Common deployment and monitoring infrastructure. M. Al-Turany, CWG13 meeting 

  3. Current status of FairRoot CbmRoot R3BRoot SofiaRoot MPDRoot PandaRoot AsyEosRoot EICRoot FopiRoot FairRoot Run Manager IO Manager MC Application Event Display Runtime DB DB Interface Task Magnetic Field Module Detector Event Generator … … Root Libraries Cint ROOT IO TTree TGeo TVirtualMC TEve Proof Geant4 Genat4_VMC Geant3 VGM … … 5/18/13 M. Al-Turany, ACAT 2013, Beijing Florian Uhlig ROOT Users Workshop, Saas Fee M. Al-Turany, CWG13 meeting 

  4. What we went to do with FairRoot CbmRoot R3BRoot SofiaRoot MPDRoot PandaRoot AsyEosRoot EICRoot FopiRoot Building configuraion Testing Transport (FairMQ) Runtime DB Fair DB MC Application Module Detector Magnetic Field Event Generator Libraries ROOT CMake Geant4 Genat4_VMC Geant3 VGM ZeroMQ … M. Al-Turany, CWG13 meeting 

  5. How is it with ALFA and FairRoot? • AliRoot6 (O2) CbmRoot R3BRoot SofiaRoot MPDRoot PandaRoot AsyEosRoot EICRoot FopiRoot ALFA FairRoot ????

Al-Turany, CWG13 meeting 

  6. Current Status • The Framework delivers some components which can be connected to each other in order to construct a processing pipeline(s). • All components share a common base called Device • Devices are grouped by three categories: • Source: • Data Readers (Simulated, raw) • Message-based Processor: • Sink, Splitter, Merger, Buffer, Proxy • Content-based Processor: • Processor M. Al-Turany, CWG13 meeting 

  7. The Dynamic Deployment System (DDS) Should: • Deploy task or set of tasks • Use (utilize) any RMS (Slurm, Grid Engine, … ), • Secure execution of nodes (watchdog), • Support different topologies and task dependencies • Support a central log engine • …. See Talk by AnarManafov on Alice Offline week (March 2014) https://indico.cern.ch/event/305441/ M. Al-Turany, CWG13 meeting 

  8. Test Cluster • 8 machines from DAQ lab with SLC6-64 • aidrefma01-08 • FairRoot + FairSoft are installed • /local/home/cwg13/install/FairRoot • Tutorial3 can be used as a demonstrator M. Al-Turany, CWG13 meeting 

  9. Some remarks • Mixture of SL6.5 and SL6.4 • Binary compatible but I had to switch off the test in config.sh • /etc/issue is not available which also require a manual change for FairRoot • Is there any way to export the display from these machines? M. Al-Turany, CWG13 meeting 

  10. First test • Two Samplers • aidrefma03 and aidrefma08 • Six Processors • aidrefma04 and aidrefma05 • One File writer (sink) • aidrefma02 M. Al-Turany, CWG13 meeting
