Transcription de la présentation

  1. Mobile AnalyzerA Distributed Computing Platform Juho Karppinen <Juho.Karppinen@hut.fi> Helsinki Institute of Physics Technology Program May 23th, 2002 Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (1)

  2. Overview • Distributed computing platform • Designed for need of high energy physics • Can be used to analyze vast amounts of data stored in a distributed fashion • Agent based concept • Implemented using Java Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (2)

  3. Basic idea • User provides java code and description of needed data • Data is found automatically using intelligence implemented to LDAP directories • Agents (analysis code) are sent where the data is and executed • Only status messages and results are sent back Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (3)

  4. Data ranges to process: 10..100, 500..1600 Architecture Resource information serverRuns “yellow pages” for needed resources User supplied dataThe code to run and a description of required data public void processEvent (Event e) { if( e.getColumn( RMC )) … } LDAP Server 1 Client Client computer gives access point Network Server 2 Proxy Server 3 Proxy server(s) Autonomous job dispatching, result saving and status monitoring Analysis serversComputers which have data and computing power for users Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (4)

  5. Technology overview • Uses Grid Security Infrastructure for security and authentication • Agents uses Java Analysis Studio –interface with some modifications • Supports JAS compatible data sources and custom ones, like Objectivity • Uses own XML-based agent platform for communication Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (5)

  6. Benefits • Supports truly heterogeneous hardwareenvironments (Solaris, Linux, Windows, ...) • Uses existing Java Analysis Studio and GSI -interfaces • Reduced workload for the user as the data location does not need to be known • Not only restricted to physics analysis. Agents gives lots of possibilities, ex real-time graphical cluster status monitoring. Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (6)

  7. Current status • Support for off-line execution of jobs • Can access private networks or clusters through proxy server • Integration with CMSIM through GridPortal, allows automated verification of results right after simulations are finished • Command line utilities Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (7)

  8. Conclusion • Mobile Analyzer has lots of potential in future. Be aware! • More information Demonstration during breaks or http://wikihip.cern.ch/twiki/bin/view/Globus/MobileAnalyzer/ Mobile Analyzer - A Distributed Computing Platform, May 23th, 2002, (9)
