  13. VDT EDG . . . LCG-1 LCG-2 EGEE-1 EGEE-2 AliEn LCG . . . Globus 2 based Web services based EGEE M/W: lifecycles • From 1st April 2004 Production grid service based on the LCG infrastructure running LCG-2 grid m/w • In parallel develop a “next generation” grid facility Produce a new set of grid services according to evolving standards (web services) Run a development service providing early access for evaluation purposes Will replace LCG-2 on production facility in 2005 Athens, 7-8th April - 13

  14. M/W: LCG EGEE builds on the work of LCG to establish a grid operations service • LCG: a collaboration of • The LHC experiments • The Regional Computing Centers • Physics institutes • Mission: • Prepare and deploy the computing environment that will be used by the experiments to analyze the LHC data • Strategy: • Integrate thousands of computers at dozens of participating institutes worldwide into a global computing resource • Rely on software being developed in advanced grid technology projects, both in Europe and in the USA Athens, 7-8th April - 14

  15. LCG components • Computing Element (CE) is a set of Worker Nodes (WN) providing computing power and the Grid Gate (GG) which is the entry node to a set of WNs. GG itself is referred to as CE. • Storage Element (SE) provides uniform access to large storage spaces. • Grid Index Information Server (GIIS) is the information server for a Grid site. Evolution towards BDII. • Replica Location Service (RLS) provides information about data location and management. There should be one RLS per Virtual Organization (VO). • Resource Broker (RB) performs workload management functions. • Logging and Bookkeeping Service (LBS) logs all job management events. It is typically collocated with the RB. • Proxy Server (PS) enables renewal of proxy certificates. In the table above this is referred to as PROX. • Virtual Organisation Server (VOS) maps user certificates to users data and is used for authorisation purposes. • User Interface (UI) provides for user access to the Grid. • LCFG is the automatic configuration server. Athens, 7-8th April - 15

  16. SA1 execution plan: overview • Planning organised by regional federation • Coordination between partners responsibility of ROC managers • Execution plan • Main part – overall organisation, responsibilities, procedures, task breakdown etc. Core is provided. • Detailed planning – detailing internal Local Operations Centre task breakdown, staffing, planning, organisation etc. TBD per country. Athens, 7-8th April - 16

  17. ROC responsibilities (summary) • Certification of new middleware releases • Coordinate release installation and configuration in the RCs and validate RCs • Provide operational support to RC managers and VO users, interact with Application/VO specific support • Solve, or refer and escalate middleware problems to relevant teams • Distribute operational monitoring, authorisation and accounting tools to RCs • Collaborate with CIC to read and check monitoring information and to react to bad performance of the running Grid services • Establish the tools measuring the service level provided by RCs computing and storage services and by other Grid services located inside their region/federation Athens, 7-8th April - 17
