This volume discusses how the novel technologies of semantic web and workflow have been integrated into the grid and grid services. It focuses on sharing resources, data replication, data management, fault tolerance, scheduling, broadcasting, and load balancing algorithms. The book discusses emerging developments in grid computing, including cloud computing, and explores large-scale computing in high energy physics, weather forecasting, and more. The contributors often use simulations to evaluate the performance of models and algorithms. In the appendices, they present two types of easy-to-use open source software written in Java.
