To achieve this goal, the workshop brought together a critical mass of well-established researchers (including 145 permanent researchers and 171 PhD students) from a number of institutions which have all constructed an ambitious joint program of activities. Priority in the workshop was given for work performed through cooperation between partners from different research institutions and to promising research proposals that could encourage such cooperation in the future. List of topics in this book include: - Knowledge and Data Management - Programming Model - System Architecture - Grid Information, Resource and Workflow Monitoring Services - Resource Management and Scheduling - Systems, Equipment and Environment - Trust and Security Issues on the Grid.
