This paper presents the performance evaluation, workload characterization and trace driven simulation of a hypercube multi-computer running realistic workloads. Six representative parallel applications were selected as benchmarks. Software monitoring techniques were then used to collect execution traces. Based on the measurement results, we investigated both the computation and communication behavior of these parallel programs, including CPU utilization, computation task granularity, message interarrival distribution, the distribution of waiting times in receiving messages, and message length and destination distributions. The localities in communication were also studied. A trace driven simulation environment was developed to study the behavior of the communication hardware under real workload. Simulation results on DMA and link utilizations are reported.
本文介绍了运行实际工作负载的超立方体多计算机的性能评估,工作负载表征和跟踪驱动的仿真。选择了六个有代表性的并行应用程序作为基准。然后使用软件监视技术来收集执行跟踪。根据测量结果,我们研究了这些并行程序的计算和通信行为,包括CPU利用率,计算任务粒度,消息到达间隔分布,接收消息中的等待时间分布以及消息长度和目标分布。还研究了交流的地方。开发了跟踪驱动的仿真环境,以研究实际工作负载下通信硬件的行为。报道了DMA和链路利用率的仿真结果。 P>
