ABSTRACT
Worldwide grid projects have contributed to the development of the grid. They have purchased or installed equipment. During these projects, numerous dedicated networks and clusters have been set up, which are currently serving as the basic resources for grid research. During the last decade, grid computing has became a very dynamic field, and many scientific computational fields are now looking for solutions toward grid computing. High energy physics, astronomy, earth observation, and biology problems are now common grid applications. In addition to science and engineering applications, e-business and computational finance have also increasingly appeared as grid applications. These applications have put forward domain-specific requirements, such as massive data processing, multisite geographically distributed databases, high performance computing and high throughput computing. Human resources in grid projects are usually organized into small groups, each group focusing on one particular aspect of the grid technology like security, data management, information and monitoring, scheduling, etc. These groups have developed useful software products and published numerous journal papers and research reports.
