An open producer and consumer management system for grid environment

Grid technologies have been widely adopted and are entering the mainstream in scientific and engineering computing. Grid technologies and infrastructures support the sharing and coordinated use of diverse resources that are geographically distributed components operated by distinct organizations and individuals with different policies. In a Grid environment, a substantial amount of runtime information requires to be gathered and delivered for various Grid services such as performance analysis, performance tuning, performance prediction, fault detection, co-scheduling and re-scheduling. Because the characteristics of runtime information are fundamentally different from the characteristics of system or program-produced data, systems that collect and distribute the information should satisfy certain requirements. Exploiting producer/consumer model, we design an open producer and consumer management framework to fit with the heterogeneous, dynamic and multi-domain nature of Grids. The security and fault-tolerance mechanisms are incorporated into the framework. Both producer and consumer are designed as Grid services and implemented using Web services technology. Based on the open framework, the management system for Grid applications monitoring is instantiated in our Grid computing project
