| 摘要: |
| 对一个动态自适应的NOW(network of workstations)协同调度算法Dasic算法进行了性能评估.通过对Dasic算法和典型的NOW协同调度算法MAX算法、Grab算法的性能模拟,在响应时间和系统流量两个主要性能指标上进行分析和比较,从而验证了在较大规模的NOW系统中,动态自适应对协同调度的性能有较大的影响. |

| Abstract: |
| In this paper, the performance evaluation of a dynamically adaptive co-scheduling algorithm——Dasic based on network of workstations is presented. In terms of the aspects of mean response time and system flow, the Dasic algorithm is compared with traditional co-scheduling algorithm MAX and Grab algorithm by simulation. The conclusion is that dynamic adaptation can strikingly improve co-scheduling performance in a massive system of network of workstations. |
| Key words: Network of workstations, co-scheduling, dynamic adaptation. |
