Marten GridKa plans for SC4 and beyond Tier 1/2 Meeting and 47 th Session of the GridKa TAB,

2 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft Tier 1/2 Meeting and 47. Session GridKa TAB, March 2006 LCG Service Deadlines full physics run first physics cosmics Pilot Services – stable service from 1 June 06 LHC Service in operation – 1 Oct 06 over following six months ramp up to full operational capacity & performance LHC service commissioned – 1 Apr 07 Service Challenge 4

3 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft Tier 1/2 Meeting and 47. Session GridKa TAB, March 2006 WLCG MB defines a set of High Level Milestones https://uimon.cern.ch/twiki/pub/LCG/Planning/WLCG_High_Level_Phase2_Plan xls 2006 SC All required software for baseline services deployed and operational at all Tier- 1s and at least 20 Tier-2 sites OPN Tier-0/1 high-performance network operational at CERN and 6 Tier-1s, at least 3 via GEANT. SC Use cases and service level support defined for SC4 CAS Castor2 Readiness Review SC All services on all Tier-1 sites monitored SC Proposal on availability levels specified in Annex 3 of the WLCG MoU SC Service Challenge 4 Set-up: Set-up complete and basic service demonstrated, capable of running experiment-supplied packaged test jobs, data distribution tested. DRC GB/s data recording demonstration at CERN SC Service Challenge 4: Start of stable service phase SC Service Challenge 4: Successful completion of service phase To be shifted by 1 month (see later)

4 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft Tier 1/2 Meeting and 47. Session GridKa TAB, March 2006 WLCG MB asks Tier-1s to provide site milestone plans https://uimon.cern.ch/twiki/bin/view/LCG/SitesPlans https://uimon.cern.ch/twiki/pub/LCG/SitesPlans/FZK_Plan xls Specifies hardware installation and configuration plans (see also TAB#46). In detail: 03/ 2006: tape access and I/O optimization tests 03/ 2006: installation of 2nd 10 Gbps OPN from GridKa to CERN 03/ 2006: delivery and installation of CPUs 04/ 2006: dCache server & write pool upgrade (throughput) 04/ 2006: 2nd Tape I/O upgrade 05/ 2006: disk delivery installation, configuration, tests 06/ 2006: start of stable SC4 services

7 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft Tier 1/2 Meeting and 47. Session GridKa TAB, March 2006 WLCG MB asks the TCG to provide a middleware deployment plan https://uimon.cern.ch/twiki/pub/LCG/Planning/SC4ServicesPlanning_ xls TCG = Technical Coordination Group Combines users requirements and middleware development plans (great work done by Flavia Donno). Resulted in SC4 Middleware (deployment) Plan Specifies, which middleware component and version will be deployed for SC4 and when. Important message: LCG 2_7_0 released for production end of January 2006 gLite 3.0 released for pre-production end of February 2006 gLite 3.0 released for production end of April 2006

14 Forschungszentrum Karlsruhe in der Helmholtz-Gemeinschaft Tier 1/2 Meeting and 47. Session GridKa TAB, March 2006 Two grid infrastructures are now in operation, on which we are able to build computing services for LHC Reliability and performance have improved significantly over the past year The focus of Service Challenge 4 is to demonstrate a basic but reliable service that can be scaled up - by April to the capacity and performance needed for the first beams. Development of new functionality and services must continue, but we must be careful that this does not interfere with the main priority for this year – reliable operation of the baseline services Summary (taken from Jamie Shiers / SC4 Mumbai)
