The Grid Observatory SSC Towards a Computer Science SSC Cécile Germain-Renaud on behalf of the GO Cluster

Overview Enabling facility towards experimental theory of large grid systems by setting up a data repository, enabling the development of behavioural grid models and supporting the deployment of software experimental facilities. Added value: the integration of its production goal – make available comprehensive and usable grid traces – and the long-term scientific goal of acquiring better knowledge and control of the grid as a complex system Builds on the previous activity of the GO cluster in EGEE-III, which has already successfully realized a grid trace portal and fostered national and international collaborations with the Computer Science community.

Scientific and engineering Scope Autonomic Computing Computer Science: Machine Learning, Distributed Systems Participants: LRI (F, CNRS IdG), MIS (France, CNRS), London Imperial College (UK), UNIPM (Italy) Ongoing discussions with CoreGrid and french national action G5K/Aladdin Support secured from the NSF Center for Autonomic Computing Planning a COST action Computer Engineering: ongoing discussions with IBM, Logica, SixSq EU project RESERVOIR EGI Operations and Middleware

Aims Community Portal Maintain a publicly accessible repository of grid traces Contribute to middleware improvement in reliability, stability and performance Foster interaction with Computer Science research (ML, AC, DS)
