2 Enabling Grids for E-sciencE INFSO-RI Enabling Grids for EsciencE What is the EGEE community? –Researchers in eScience (applications NA4) –eResearch –European community –World grid community –Industry (industry forum) What is not the EGEE community?

3 Enabling Grids for E-sciencE INFSO-RI eScience/eResearch EGEE’s initial focus is on specific scientific communities –High Energy Physics (Large Hadron Collider) –Biomedical –Geology –Chemistry –Astrophysics Collaborating with other EU projects in other areas –For example, digital libraries - DILIGENT

4 Enabling Grids for E-sciencE INFSO-RI Applications in EGEE Production service supporting multiple VOs with different requirements –Data  Volume  Location – distributed?  Write Once or Update?  Metadata archives?  Controlled or open access? –Computation  High throughput (~ current LCG)  High performance, supercomputing –No. of sites, scientists,… Establish viable general process to bring other scientific communities on board

5 Enabling Grids for E-sciencE INFSO-RI An EGEE community EGEE communities are based around the idea of Virtual Organisations. A Virtual Organisation: –Owns shared computing resources –Authorises and authenticates its members access to resources –Manages its own resources

6 Enabling Grids for E-sciencE INFSO-RI EGEE: adding a VO EGEE has a formal procedure for adding selected new user communities (Virtual Organisations): Negotiation with one of the Regional Operations Centres Seek balance between the resources contributed by a VO and those that they consume. Resource allocation will be made at the VO level. Many resources need to be available to multiple VOs : shared use of resources is fundamental to a Grid

7 Enabling Grids for E-sciencE INFSO-RI The role of the pilot applications – HEP and Biomedicine Initial area of focus to establish a strong user base on which to build a broad EGEE user community Provide early feedback to the infrastructure activities on their experience with application deployment and VO management Act as guinea pigs and provide early feedback to the middleware developers on their experience with new services

8 Enabling Grids for E-sciencE INFSO-RI EGEE pilot application: Large Hadron Collider Mont Blanc (4810 m) Data Challenge: –10 Petabytes/year of data !!! –20 million CDs each year! Simulation, reconstruction, analysis: –LHC data handling requires computing power equivalent to ~100,000 of today's fastest PC processors! Operational challenges –Reliable and scalable through project lifetime of decades Downtown Geneva

9 Enabling Grids for E-sciencE INFSO-RI The characteristics of pilot HEP applications Very large scale from project day 1 Virtual Organizations were already set up at project day 1 Very centralized: jobs are sent in a very organized way Multi-grid: data challenges are deployed on several grids –ALICE LCG, Alien –ATLAS LCG, US Grid2003, Nordugrid –CMS LCG, US Grid2003 –LHCb LCG, Dirac

11 Enabling Grids for E-sciencE INFSO-RI The LHC Experiments

12 Enabling Grids for E-sciencE INFSO-RI Overview of experiences with LHC data challenges There was continual evolution throughout 2004, with LCG and experiments gaining more experience in the development and use of an expanding LCG grid All experiments had excellent relations with LCG-EIS support – a model for the future support of VOs Global job efficiencies ranged from 60-80% as experience developed – must get up to 90+% for user analysis - look to new middleware developments and tighter operational procedures Sources of problems and losses –Site configuration, management and stability –Data Management (especially metadata handling) –Difficult to monitor job running and causes of failure D0 in early 2005 showed that one can run with good efficiency with a set of well controlled sites

14 Enabling Grids for E-sciencE INFSO-RI The characteristics of biomedical pilot applications Prototype level at project day 1 VO was created after the project kicked-off Very decentralized: application developers use the grid at their own pace Very demanding on services –Compute intensive applications –Applications requiring large amounts of short jobs –Need for interactivity or guaranteed response time Resources were focused on the deployment of large scale applications on LCG-2 –Integration of Biomed VO used to identify issues relevant to all VOs to be deployed during EGEE lifetime –Decentralized usage of the infrastructure highlights different weaknesses from the more centralized HEP data challenges
