Grid Computing requires the use of software that can divide & farm out pieces of a program to as many as several thousand computers. This book explores processes & techniques needed to create a successful Grid infrastructure. Leading researchers in Europe and the US look at the development of specialist tools & environments which will encourage the convergence of the parallel programming, distributed computing & data management communities.Specific topics covered include:? An overview of structural & behavioural properties of Computer Grid applications ? Discussion of alternative programming techniques ? Case studies displaying the potential of Computer Grids in solving real problems This book is unique in its outline of the needs of Computational Grids both in integration of high-end resources using OGSA/Globus, & the loose integration of Peer-2-Peer/Entropia/United Devices. Readers will gain an insight on the limitations of existing approaches as well as the standardisation activities currently taking place.
