Cluster technologies for high performance computing

A cluster system is extending its ability, owing to the increase of transmission speed and interface speed between nodes and interconnect. Synfinity interconnect can carry out the routing and transfer the massages at the speed of gigabyte/s. The bottleneck problem raised in a conventional cluster system must be solved by improvements such as transmission speed and protocol. Based on the standard interface, any kind of commodity like the latest PCs, WSs and SMPs can be applied as a node computer. That makes the cluster system more attractive from the point of view of availability, usability, flexibility, scalability and cost performance. Moreover, a parallel program on the cluster system can be written by using a newly-developed message communication library, without paying any attention to the communication between inter- and intra-node. The cluster system will be also used instead of a parallel computer, MPP and the so called supercomputer, and it has new features of shared memory view
