重新启动是一种常见的技术,用于改善复杂系统的响应时间,其中延迟的原因无法识别,或者用户无法解决。通过重新启动,用户中止超过最后期限的运行作业,并立即将其重新提交给系统。在许多常见的场景中,这种方法可以减少用户体验的响应时间。对于只有一个用户应用重新启动的场景,以及通常可以忽略延迟影响的情况,重新启动已经得到了很好的研究。在本文中,我们将探讨的问题,重新启动的情况下,许多用户在一个系统中,可以建模为一个开放的网络。我们应用G-网络形式主义来解决这个问题。我们使用负客户来模拟请求的中止和重试。开放的G-网络使用多个类与相位型分布式服务时间。这允许近似于抢占式重复不同的行为,因为它对于请求的多次重启是自然的。我们计算了一个请求的响应时间,并证明了可以找到一个最佳的重启间隔,并将结果与仿真结果进行了比较。
Restart is a common technique for improving response-times in complex systems where the causes of delays can either not be discerned, or not be addressed by the user. With restart, the user aborts a running job that exceeds a deadline, and resubmits it to the system immediately. In many common scenarios, this approach can reduce the response-times that the user experiences. Restart has been well-studied for scenarios where only one user applies restart, and typically in cases where queueing effects can be neglected. In this paper we approach the question of restart in a scenario where restart is applied by many users in a system that can be modelled as an open queueing network. We apply the G-Networks formalism to this problem. We use negative customers to model the abortion and retry of a request. The open G-network uses multiple classes with phase-type distributed service times. This allows the approximation of a preemptive repeat different behaviour as it is natural for multiple restarts of a request. We compute the response time of a request and show that an optimal restart interval can be found. The results are compared with simulation.
