| 摘 要： | 主要叙述两种基于WS Cluster(WSs即工作站集群)环境的分布式并行处理的有效性算法.第1种算法是在WSs间的关系数据比较小的表算法.另一种算法是对数据通信应用转换操作和对独立数据每接点进行大量搜索过程的简化,通过这些算法在WSs中的实施,并对它们的性能作出评价.

| Abstract: | It was mostly described two neweffective algorithms for parallel processing distributed in a WSCluster environment. One was an algorithm in which the size of data transmitted between WSs was Smaller than that of the former algorithm. The other was an algorithm that reduced the number of scan processings at each node by dividing data and that used shift operations for data communication, and had implemented these algorithms on a WSs and had evaluated their performance. |
