  1. MUPJ - gLExec update MB, 2013-05-14 Maarten Litmaath CERN

  2. Nagios tests for “ops” • Each NGI/ROC needs to submit its own tests • Register at least 1 DN with pilot role in “ops” VO • Configure SAM-Nagios to submit the tests • Thanks to EGI essentially done • Each EGI site supporting glexec needs to update the GOCDB • A “gLExec” flag for each CE supporting glexec on the WN • A lot of sites and CEs still to be done • EGI added alarm to operations profile in Dec (not yet A/R) • Automatic tickets for sites whose “gLExec” tests fail • Results are available in MyWLCG • http://cern.ch/go/fgz8 • Currently only 117 CEs present, including ~all T1 with CREAM • Was 104 on Jan 15 Maarten Litmaath (CERN)

  3. gLExec deployment campaign • A few more sites claim glexec support in the BDII • 88 = 64 EGI + 24 OSG on May 13 • Was 82 = 59 + 23 on Jan 14 • As usual some sites now appear, others disappeared … • Downtime? • Reconfiguration? More likely! • Some T2 consistently OK in MyWLCG, but most are absent • https://twiki.cern.ch/twiki/bin/view/LCG/GlexecDeployment • Updated Apr 22 • How to implement gLExec on the WN • Includes example script for Argus configuration • Provided by Antonio Delgado of CIEMAT  OK site in MyWLCG!

  5. Nagios tests for LHCb • https://sam-lhcb-prod.cern.ch/nagios/cgi-bin/status.cgi? servicegroup=SERVICE_CREAM-CE&style=detail Maarten Litmaath (CERN)

  7. Test results for ATLAS https://sam-atlas-prod.cern.ch/nagios/cgi-bin/status.cgi? servicegroup=SERVICE_CREAM-CE&style=detail https://sam-atlas-prod.cern.ch/nagios/cgi-bin/status.cgi? servicegroup=SERVICE_OSG-CE&style=detail Maarten Litmaath (CERN)

  8. Experiment plans • CMS • Opening tickets against sites where glexec does not work • Enabling glexec in GlideinWMS per site where it works • ATLAS • Re-implementing glexec usage by pilot • ALICE • Implementing Security TEG proposal may be viable • Use of specially crafted proxies with critical extension that is only understood by glexec • LHCb • Re-enabled and tested glexec support in DIRAC • Ran into gLExec infrastructure issues at many sites Maarten Litmaath (CERN)
