This document summarizes updates related to grid computing since the last meeting in December 2008. It discusses resource upgrades at KEK, including an additional 2.5 million SPECint2000 by December 2009 and another 2.5 million by March 2010. Plans are outlined to deploy a storage service in early 2010 to expose tape storage to the grid. Operational statistics show over 1,000 ILC jobs run, accounting for around 10% of CPU time and over 1 petabyte of storage used. ILC is reported as the heaviest computing resource consumer at KEK in the past 6 months. Several pending items are also noted including FTS deployment and reconstruction of the KEK-1 grid site.

4. KEK’s Contribution in EGEE-III TSA1.1: Grid Management Interoperability and collaboration TSA1.2: Grid operations and support 1st line support for operations problems Middleware deployment and support Coordination of middleware deployment and support for problems. Regional certification of middleware releases if needed (outside of PPS and SA3 involvement). This is anticipated to be very rare and will require specific justification.

14. Summary Table of Resource Scale Dec 3, 2009 ILC Detector Workshop -- Updates related on Grid since last meeting in December 2008 14 Sorry for confusion! A bit revised: “System C is now available and D will be in operation in Next March” is incorrect. It should be corrected that “Half of both System C and System D is now available and another half will be in operation in Next March”. Up Down Legend

15. Upcoming Storage Service To expose HSM to Grid SRB-DSI to bridge SRB inside BCS Just for GridFTP access, not for SRM and LFC To enable access with logical file name, e.g. lcg-xxx lfn://logical-file-name SRM-SRB for Site URL, e.g. srm://srm.kek.jp/ SRB-DSI for Transfer URL, e.g. gridftp://disk.kek.jp/ A bit behind of schedule Dec 3, 2009 ILC Detector Workshop -- Updates related on Grid since last meeting in December 2008 15
