> 中文摘要: 子网分配问题是指识别并分配一个空闲的、满足指定大小要求的节点机.首先,提出了网格结构中一种新的具有O(N2a·1og2Na)时间复杂度的空闲子网搜索算法,它优于现有的O(N3a)时间复杂度的搜索算法.然后,用该算法对基于保留因子的最佳匹配类子网分配算法——RF(reservation factor)算法进行了改进,得到了

Abstract:The submesh allocation problem is to recognize and allocate a free submesh that can accommodate a request for a submesh of a specified size. Firstly, a new algorithm of searching free submesh for mesh multicomputers is proposed, which time complexity is O(N2a·log2Na), better than those existed algorithms whose time complexity are O(N3a) . Then this new algorithm is used to improve the best fit allocation scheme which is based on reservation factor--RF scheme, and the result is better than it.
