Quicksort on a Linear Array with a Reconfigurable Pipelined Bus System

چکیده
Based on the current fiber optic technology, a new computational model, called a linear array with a reconfigurable pipelined bus system (LARPBS), is proposed in this paper. A parallel quicksort algorithm is implemented on the model, and its time complexity is analyzed. For a set of N numbers, the quicksort algorithm reported in this paper runs in O(log, N) average time on a linear array with a reconfigurable pipelined bus system of size N. If the number of processors available is reduced to P, where P < N, the algorithm runs in O((N/ P) log, N) average time and is still scalable. Besides proposing a new algorithm on the model, some basic data movement operations involved in the algorithm are discussed. We believe that these operations can be used to design other parallel algorithms on the same model. Future research in this area is also identified in this paper.

Fast Sorting on a Linear Array with a Reconfigurable Pipelined Bus System
We present a fast algorithm for sorting on a linear array with a reconfigurable pipelined bus system (LARPBS), one of the recently proposed parallel architectures based on optical buses. Our algorithm sorts numbers in worst-case time using processors. To our knowledge, the previous best sorting algorithm on this architecture has a running time of .

The known fast sequential algorithms for multiplying two N N matrices (over an arbitrary ring) have time complexity O(N ), where 2 < < 3. The current best value of is less than 2.3755. We show that for all 1 p N , multiplying two N N matrices can be performed on a p-processor linear array with a reconfigurable pipelined bus system (LARPBS) in O(N =p + (N=p ) log p) time. This is currently the f...
