This book constitutes the refereed proceedings of the European Grid Conference, EGC 2005, held in Amsterdam, The Netherlands in February 2005. Focusing on all aspects of Grid computing and bringing together participants from research and industry, EGC 2005 was a follow-up of the AcrossGrids Conferences held in Santiago de Compostela, Spain (2003) and in Nicosia, Cyprus (2004).

The 121 revised papers presented - including the contribution of three invited speakers - were carefully reviewed and selected from over 180 submissions for inclusion in the book and address the following topics: applications, architecture and infrastructure, resource brokers and management, grid services and monitoring, performance, security, workflow, data and information management, and scheduling fault-tolerance and mapping.
