Architecture and grid application of cluster computing system

Recently, people pay more attention to the grid technology. It can not only connect all kinds of resources in the network, but also put them into a super transparent computing environment for customers to realize mete-computing which can share computing resources. Traditional parallel computing system, such as SMP(Symmetrical multiprocessor) and MPP(massively parallel processor), use multi-processors to raise computing speed in a close coupling way, so the flexible and scalable performance of the system are limited, as a result of it, the system can't meet the requirement of the grid technology. In this paper, the architecture of cluster computing system applied in grid nodes is introduced. It mainly includes the following aspects. First, the network architecture of cluster computing system in grid nodes is analyzed and designed. Second, how to realize distributing computing (including coordinating computing and sharing computing) of cluster computing system in grid nodes to construct virtual node computers is discussed. Last, communication among grid nodes is analyzed. In other words, it discusses how to realize single reflection to let all the service requirements from customers be met through sending to the grid nodes
