| 摘要: |
| 本文在一个EREW PRAM(exclusive read exclusive write paralled random accessmachine)上提出一个并行快速排序算法,这个算法用k个处理器可将n个项目在平均O((n/k+logn)logn)时间内排序.所以平均来说算法的时间和处理器数量的乘积对任何k≤n/logn是
O(nlogn). |

| Abstract: |
| A parallel quicksort algorithm is given and which,given an EREW PRAM with k processors,sorts n items in expected O((n/k+logn)logn)time.and thus the prod-uct of time and number of processors is O(nlogn)on the average for any value ofk≤n/(logn). |
