Grid computing prototype based on Internet

To share distributed resources and save computing cost, a grid prototype I-GRID based on Internet is designed and implemented. I-GRID is a set of heterogeneous computing resources that can be used as a whole. I-GRD is characterized by a method for supporting hosts to dynamically join as a node, a communication model for transparent conversion between heterogeneous data formats using MDI, a single-image file system implemented with object-oriented techniques, and the interfaces to popular parallel programming systems like PVM. Jacobi iteration test shows that I-GRID is not only practical, but also real-time. I-GRID will give campus network users a high-performance environment with uniform programming interface.
