  1. MICE on the GRID Malcolm Ellis 28th April 2005

  2. History • Software meeting at RAL (November 2004), Gidon Moont described IC work on a GRID portal and collected requirements from MICE. • 2005 – First version of portal goes “live”, I obtained a certificate and recently joined the dteam VO to allow test jobs on the LCG. • Following slides show process of preparing and submitting a G4MICE job (based on the example shown at the LBNL collaboration meeting) and retrieving the results. • Statically linked executables, compiled from the release mice-1-0 were used.

  3. How to run a G4MICE job • Register, receive certificate and join VO. • Log on to portal and setup proxy certificate. • Prepare job (executable plus any other files). • Upload files to portal. • Select files to be submitted, and output files to be retrieved then launch job. • Monitor status of job. • Retrieve output (stdout, stderr and other nominated files). • Be impressed by results...

  4. Input Tracker: True Emittance = 6.218 p mm rad Rec. Emittance = 6.221 p mm rad Output Tracker: True Emittance = 5.442 p mm rad Rec. Emittance = 5.448 p mm rad Transverse Cooling: True = 12.5 % Rec. = 12.4 %

  5. Other jobs • Some of the machines that my test jobs have run on: • griditce01.na.infn.it:2119/jobmanager-lcgpbs-infinite • lcgce01.gridpp.rl.ac.uk:2119/jobmanager-lcgpbs-dteamL • grid008.to.infn.it:2119/jobmanager-lcgpbs-cert • grid-ce.desy.de:2119/jobmanager-lcgpbs-infinite • skurut17.cesnet.cz:2119/jobmanager-lcgpbs-long • ce32.hep.ntua.gr:2119/jobmanager-lcgpbs-dteam • virgo-ce.roma1.infn.it:2119/jobmanager-lcgpbs-long • lcg02.ciemat.es:2119/jobmanager-lcgpbs-dteam • lcg-gridka-ce.fzk.de:2119/jobmanager-pbspro-long • ce-a.ccc.ucl.ac.uk:2119/jobmanager-lcgpbs-dteam • ce001.imbm.bas.bg:2119/jobmanager-pbs-medium

  6. What is next? • Yagmur and I will work with Gidon to continue testing of the portal and MICE applications. • Before serious productions can be started, we need a MICE VO (the dteam one I’m on is only for development and testing) • Breaking news – a MICE VO has just been set up!!! Paul Kyberd and I will be testing it out in the coming weeks... • Need to learn more about more advanced job control (random number seeds, data storage, etc...) • Hope to be able to start using the GRID for serious MICE work soon, so contact your local GRID person and get registered!
