存在数据密集型计算作业的调度

Scheduling in the Presence of Data Intensive Compute Jobs

Amir Behrouzi-Far, Emina Soljanin

摘要:

我们研究了非自适应调度策略在多服务器计算系统中的性能。计算工作大多是定期的,服务要求不高。然而,也有零星的数据密集型作业,其预期的服务时间是远远高于定期作业。对于这个模型,我们感兴趣的是调度策略对作业在系统中平均花费时间的影响。为此,我们在一个简化的,只到达系统中引入两个性能指标。我们相信,这些性能指标是很好的预测排队系统中的政策,这是支持模拟结果的相对性能。

英文摘要:

We study the performance of non-adaptive scheduling policies in computing systems with multiple servers. Compute jobs are mostly regular, with modest service requirements. However, there are sporadic data intensive jobs, whose expected service time is much higher than that of the regular jobs. Forthis model, we are interested in the effect of scheduling policieson the average time a job spends in the system. To this end, we introduce two performance indicators in a simplified, only-arrival system. We believe that these performance indicators are good predictors of the relative performance of the policies in the queuing system, which is supported by simulations results.
