ABSTRACT
In the past ten years, grid computing has been heavily researched and developed. At the present, grid technology has matured enough to enable the realization of workable and commercial infrastructures, platforms and tools, ready to be used in production environments ranging from scientific to commercial application domains. Technology research has gained a dramatic development, involving major advances in areas such as resource management, mapping, scheduling, fault tolerance, I/O, visualization, performance analysis, programming languages and environments, resource discovery and semantic aspects.
