  1. WLCG Operations Coordination Andrea Sciabà IT/SDC GDB11th September 2013

  2. Outline Status of task forces News from EGI Conclusions WLCG Operations Coordination – A. Sciabà

  3. Middleware news • perfSONAR now tracked in baseline versions table • End of support for dCache 1.9.12 was extended to September 30 • Due to delay in releasing SHA-2 ready version • dCache 2.2.17 (just released) is SHA-2 compliant • All sites should update their BDIIs to the latest version, including fixes for GLUE-2 and security WLCG Operations Coordination – A. Sciabà

  4. gLExec • Tickets opened to sites • 39 closed and verified • 55 still open (but many on hold until mid/late autumn to unify with SL6 migration) • Some countries already done, in particular France • CMS will make the gLExec SAM test critical by late fall WLCG Operations Coordination – A. Sciabà

  5. SHA-2 • Will be covered in detail today by Peter • Just a few highlights • WLCG “deadline” extended to December 1st • By then we expect users to be able to use SHA-2 certificates for their work • It should be compatible with measured state and progress • Validation status by experiment • ALICE: various software still to be checked • ATLAS and LHCb: all central services verified • CMS: all OK but for DBS-2 (soon to be decommissioned anyway), end-to-end job submission tests done • Need testing job submission with SHA-2 certificates for pilots • VOMRS → VOMS-Admin migration • IT to deploy VOMS-Admin servers for the VO managers to test • Migration will be fully automated • In the worst case, VOMRS can still be used if users authenticate with it using a SHA-1 certificate and register DN and CA of their new SHA-2 certificate WLCG Operations Coordination – A. Sciabà

  6. CVMFS • Patch released with security fix, sites should upgrade or apply hot fix • ALICE • 33/51 sites deployed it, the rest by this fall: excellent progress! • CMS • Using gLite UI from CVMFS for Parrot • Only ~10 CMS sites remaining! • New “CVMFS” SU in GGUS under “File System” WLCG Operations Coordination – A. Sciabà

  7. FTS-3 • ATLAS, CMS and LHCb using FTS3 for functional tests or production transfers • Up to 30% of ATLAS production transfers • Using CERN (Oracle, MySQL) and RAL (MySQL) instances • Instances at PIC, IN2P3-CC and ASGC not yet used • Some bugs found under load and fixed • Overall, very impressive results WLCG Operations Coordination – A. Sciabà

  8. Tracking tools evolution • Savannah-to-JIRA migration • Completed migration for some ALICE and LHCb trackers • ATLAS wrote the list of projects to migrate • Meetings in October to discuss various issues • Savannah→JIRA for experiments and for the GGUS tacker • New GGUS functionality (e.g. tickets to multiple sites) • Savannah→GGUS for CMS WLCG Operations Coordination – A. Sciabà

  9. Middleware readiness verification • Basically consisting in testing middleware and service updates on O(10) volunteering sites on a fraction of their production resources by running real workflows • Extends staged rollout using WLCG use cases • Membership (and coordinators) to be defined • Start from the “old” middleware deployment TF? WLCG Operations Coordination – A. Sciabà

  10. News from EGI operations • At the EGI Technical Forum (16-20/9) there will be training for site admins • Including how to correctly publish information in GLUE-2 • Discussion started on the opportunity to include Frontier/Squid in UMD • It implies staged rollout, early adopters, etc. • To be seen how many sites would find it more convenient. Feedback? WLCG Operations Coordination – A. Sciabà

  11. Conclusions • Several task forces and activities on a very good track • Progress measured by numbers of sites/tickets • Machine/job features TF fully set up, ready to start • Middleware readiness verification TF still to set up • Next WLCG Operations Coordination meeting on 19th September WLCG Operations Coordination – A. Sciabà
