Service Challenge 4 Pilot Services – stable service from 1 June 06 2006 LHC Service in operation– 1 Oct 06over following six months ramp up to full operational capacity & performance cosmics 2007 LHC service commissioned – 1 Apr 07 first physics full physics run 2008 LCG Service Deadlines
WLCG MB defines a set of High Level Milestones https://uimon.cern.ch/twiki/pub/LCG/Planning/WLCG_High_Level_Phase2_Plan-20060112.xls To be shifted by 1 month (see later)
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-20060121.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

PBSPro fair share after delivery of CPUs in production 49 % LHC 51 % nLHC 1-Apr-2006 The default (test) queue is not handled by the fair share. These 20-30 CPUs are kept free for test jobs.
WLCG MB asks the TCG to provide a middleware deployment plan • TCG = Technical Coordination Group • Combines user’s 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. https://uimon.cern.ch/twiki/pub/LCG/Planning/SC4ServicesPlanning_06-01-30.xls • 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
gLite-3.0 gLite-3.2 gLite-3.x • February • March • April • May • June • July • August • September • October certification p-ps deploy certification p-ps production deploy production SC4 LHC Pilot service Middleware release schedule 2006 (acc. to Maite Borosso Lopez, EGEE ROC managers meeting, 21-feb-2006) Likely not the final schema !
Middleware deployment plans per site https://uimon.cern.ch/twiki/pub/LCG/Planning/SC4SiteServicesPlan.xls • have been prepared by all Tier-1s • were discussed in Mumbai (SC4 workshop) together with • mw development plans • mw requirements by LHC VOs (applications) • time scales for activities of LHC VOs • A summary of the Mumbai workshop was • prepared by J.Shiers, I.Bird, T.Cass, L.Robertson • submitted to LCG MB for comments • submitted to LCG GDB for comments and approval
New functionality Evaluation & developmentcycles Possible components for later years Additional planned Functionality to be agreed & completedin the nextfew months then - testeddeployed SRM 2 test and deployment Plan being elaborated SC4 3D distributed database services development test Subject to progress& experience October? ?? WLCG medium term evolution
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 2007 -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)
