Configuration Method of Multiple Clusters for the Computational Grid

A Java-Internet cluster platform (JIP) is designed as a computing platform on the computational grid in order to utilize a large collection of computing resources on the Internet. For this goal, a basic cluster module of JIP is defined as a cluster of heterogeneous systems connected to a high-speed network. For a scalable JIP configuration on the computational grid, the basic cluster module can be expanded into a logical set of multiple clusters. JIP is featured with a Java based programming environment, a dynamic resource management scheme, and an effcient parallel task execution mechanism. A multiple cluster configuration is applied to decrease communication time, which is a major bottleneck of performance enhancement. According to the analysis, multiple cluster configuration can enhance the performance of JIP about 2.5 ~ 3 times depending on any application chosen comparing with a single basic cluster configuration.
