Based on the analysis of the high performance cluster and the comparison of the cluster ' s network , the thesis chooses the scalable coherent interface ( sci ) to design the cluster , and then realizes the weather parallel application on it 本文通過對高性能集群技術的分析和對集群互連網絡的測試比較,選用sci可擴展一致性接口技術設計了一個高性能集群,并實現了氣象并行計算在高性能集群上的應用。
