Global Deployment Status Report for ATLAS Computing Integration Meeting - April 2014

This report outlines the key updates and operational status from the ATLAS Computing Integration and Operations Meeting held on April 16, 2014. Highlights include the integration of SFU-LCG2 in Canada, connectivity issues at several major Tier 1 centers, restructuring of redirection in North America, and ongoing testing of new dCache redirector plugins. Additionally, operational transfers and throughput results over the past three months are summarized, alongside developments for improved functionality and efficiency within the ATLAS computing framework.

  1. FAX status report Ilija Vukotic Computation and Enrico Fermi Institutes University of Chicago US ATLAS Computing Integration and Operations Meeting April 16, 2014

  2. Global Deployment Status • SFU-LCG2 (CA cloud) joined • Direct dCache • Connected to xrd-central • Mayor T1s missing • CA –TRIUMF – good progress • ES – pic – working with them • FR – Lyon – progress stalled • NL – Sara, Nikhef – no progress

  3. North American Redirectors • Restructuring of the redirection tree in North America • Hosted at BNL; FAX operations team provides configuration and operational support • atlas-xrd-us.usatlas.org • North American region • atlas-xrd-east.usatlas.org • -BNL, BU, Victoria, Scinet • atlas-xrd-central.usatlas.org • MWT2, AGLT2, OU, SWT2 • atlas-xrd-west.usatlas.org • SLAC, TRIUMF, McGill, SFU • Status and timeframe: • Hosts and configurations ready. Waiting for git repository’s connection.

  4. Global SSB: most sites are stable

  5. US FAX status: past three months

  6. Operational Transfers finished Throughput XROOT • Network saturation occurrence at FZK-LCG2 • ALICE analysis is suspect • If it needs an analysis to find who/what is responsible, then the monitoring is inadequate. Transfers finished Throughput FTS

  7. DEFINITION: Rate in MB/s measured between WN and a FAX endpoint Cost Matrix - US • Averaged over last week

  8. Failover Statistics – last two weeks

  9. Testing & Development • New dCache redirector plugin developed • Provides simpler federating, improves efficiency and stability of dCache endpoints. • 100Gbps tests as soon as MWT2-BNL circuit available • Testing overflow now the new test pilot is available • Working with EOS on finding solution to a too many DDM endpoints issue • Wei continuously testing using input files from analysis jobs. • Restarting frameworks measuring and following IO characteristics of ATLAS data formats – in particular xAOD.
