EGEE activities in Greece

• SA1: GRID Operations, Support and Management

• NA3: User Training and Induction

• NA5: Policy and International Cooperation

Athens, 27-28th May - 7

Our collective aim

• SA1: build expertise and operational procedures that will allow Greece to:• Integrate into European production-level infrastructure• Operate a self-standing coherent Grid infrastructure• Create teams of core experts for the future

• NA3: train and inform users, operators, etc.

• NA5: contribute to whitepapers, standards etc on the international stage

• If we do this, EGEE-2 will follow!

Athens, 27-28th May - 8

SA1 objectives in Greece: detail

• Pre-production infrastructure: smaller sites with next generation m/w• 8/5 support, crucial as real-life testbeds, for m/w and application testing

• Production infrastructure: only stable clusters with significant resources can be admitted to the EGEE production infrastructure

• 24/7 operation, supported by RC, ROC and CICs

• Run a Regional Operations Centre• One in each federation• Provide front-line support to users and resource centers• Support new resource centers joining EGEE in the regions• Support deployment and operations in the resource centers

• Key specific ROC services: security, helpdesk/TT, portal, monitoring, m/w certification, installation procedures, core Grid services, etc.

Athens, 27-28th May - 9

NA3 objectives: overall and GR

• Train the GRID community and wider user community

• Establish a training center in each region

• 5 regions

Athens, 27-28th May - 10

NA5

• General GRID and specific technical whitepapers

• Aegean & AUEB2

Athens, 27-28th May - 11

Pre-production service

• Smaller sites

• New generation m/w (EGGE-1 or LCG-2)

comming soon (15 Jun 2004 ??)

• Crucial for testing and experimentation

• Activities similar to those for production service

Athens, 27-28th May - 12

SA1 objectives: detail

• Core infrastructure services: • Operate essential grid services

• Grid monitoring and control: • Proactively monitor the operational state and performance, • Initiate corrective action

• Middleware deployment and resource induction: • Validate and deploy middleware releases• Set up operational procedures for new resources

• Resource provider and user support: • Coordinate the resolution of problems from both Resource Centres and users• Filter and aggregate problems, providing or obtaining solutions

• Grid management: • Coordinate ROCs and CICs• Manage the relationships with resource providers via service-level agreements.

Athens, 27-28th May - 13

Operations centers: hierarchy

Athens, 27-28th May - 14

M/W: lifecycles

• From 1st April 2004Production grid service based on the LCG infrastructure running LCG-2 grid m/w

• In parallel develop a “next generation” grid facilityProduce a new set of grid services according to evolving standards (web services)

Run a pre-production service providing early access for evaluation purposes

Will replace LCG-2 on production facility in 2005

Specific responsibilities

• UoA+IASA+GRNET-HQ: m/w certification; release documentation, etc. Certification testbed by IASA/UoA.

• UoA+Demokritos: Guidelines for configuration and automatic installation tools. Run local installation testbed to verify installation procedures.

• CTI: helpdesk, knowledge database, coordination of the support procedures.• UoC: EGEE-SEE website/portal.• IASA, UoA, Auth, ICCS: host and co-manage necessary core GRID services,

as agreed with GRNET-HQ.• ICS-FORTH: Coordinate the monitoring service (GridIce server + database).• Auth and Aegean: security. Auth operates the CA; Aegean provides support

and specific authorisation activities, site security guidelines, RA.• Demokritos: certification/installation + application specific support• Training: all operations people should support!

• Specific responsibilities start ASAP
