  1. Overview of user client usage: ARC Iván Márton Zsombor Nagy

  2. Why ARC clients? • Easy-to-install (yum install nordugrid-arc-client) • Easy-to-configure • Based on ARClib (ARC client library) • multi-platform support (Windows!, various Linuxes, Solaris, OS X) • language binding (java, python) • plugins for pre-WS ARC (ARC0), WS ARC (ARC1), CREAM, BES • job description translation (JSDL, JDL, xRSL) Overview of user client usage: ARC

  3. Job life-cycle • Having an idea • Create valid credentials for grid usage • Compose job (collect input files, write the program, write job description) • Submit job to the grid • Check job status (if you are curious) • Get the result • Rejoice Overview of user client usage: ARC

  5. arcproxy [--voms testers.eu-emi.eu] [--old] • arcproxy –I • arcinfo pgs03.grid.upjs.sk • cat <<EOF > myjob.xrsl&(executable="/bin/echo")(arguments="Hello World")(stdout="hello.txt")EOF • arcsub –c pgs03.grid.upjs.sk myjob.xrsl -dump • arcsub –c pgs03.grid.upjs.sk myjob.xrsl • arcstat JOBID or arcstat -a • arccat JOBID or arccat -a • arcget JOBID or arcget –a • arcinfo pgs03.grid.upjs.sk:50000/arex • arcsub –c pgs03.grid.upjs.sk:50000/arex myjob.xrsl –dump • arcinfo lxbra2308.cern.ch • arcsub -c lxbra2308.cern.ch myjob.xrsl –dump Overview of user client usage: ARC
