WLCG Operations Coordination Andrea Sciabà IT/SDC GDB 11 th September 2013

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

Middleware news  perfSONAR now tracked in baseline versions table  End of support for dCache was extended to September 30  Due to delay in releasing SHA-2 ready version  dCache (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 3

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 4

SHA-2  Will be covered in detail today by Peter  Just a few highlights  WLCG “deadline” extended to December 1 st  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 5

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” 10 July 2013 WLCG Operations Coordination – A. Sciabà 6

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 10 July 2013 WLCG Operations Coordination – A. Sciabà 7

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 10 July 2013 WLCG Operations Coordination – A. Sciabà 8

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? 10 July 2013 WLCG Operations Coordination – A. Sciabà 9

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? 10 July 2013 WLCG Operations Coordination – A. Sciabà 10

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 19 th September 10 July 2013 WLCG Operations Coordination – A.
