A Fast Parallel Sorting Algorithm Based on the Reconfigurable Optical Pipeline Bus

基于流水光总线的可重构线性阵列系统 (LARPBS)是一种建立在光总线上的并行计算模型。本文提出了一种基于LARPBS模型的快速排序并行算法 ,该算法使用n个处理器 ,对关键字位数固定的n个记录可以在O( 1 )时间完成排序 ;对于关键字位数不固定的n个记录 ,可以在O(d)时间完成排序 。

Linear array with reconfigurable pipelined bus system (LARPBS) is a parallel computational model based on the optical bus. In this paper we develop a fast parallel sorting algorithm based on LARPBS. Using n processors, the algorithm can sort n records whose keys have a fixed length in O(1) time. It can also sort n records whose keys have arbitrary lengths in O(d) time, here d is the maximum length of the keys.
