A grid service-based engineering computation architecture

Grid computing is becoming a new computing infrastructure for large-scale scientific computation and cooperative work. The Globus toolkit is the most popular grid environment and de facto grid standard, and it has adopted OGSA architecture to provide applications with grid service level. This study focuses on the requirement for scientists in engineering computation field and narrows the gap between grid service and the engineering community. The engineering computation architecture supplies the users with a visual application development and deployment environment for engineering computation. The whole is characterized by grid service. At the same time, QoS driven user-centric scheduling, community-based efficient authorization and flexible task management are designed and implemented.
