Abstract:

In this paper, based on the Itanium-2 CPU, a cluster computing system is designed and implemented. In order to utilize the merits of the cluster system and avoid its demerits, a parallel software for meteorological applications is optimized on I/O, communication cost, computation cost and the cache ut   ilization of communication data, considering the characteristics of Itanium-2 and the cluster system. The test result indicates that this cluster systemis suitable for the efficient parallel computing of the parallel software for meteorological applications.
