基于M/M/1排队系统的三值光学计算机任务服务模型

Servicing model of a ternary optical computer using M/M/1 queuing system

确保QoS是三值光学计算机在商业上成功的关键因素。在分析三值光学计算机任务管理系统各模块的基础上,基于M/M/1排队系统和串联队列以及先到先服务策略建立其服务模型。用系统平均响应时间分析和评价三值光学计算机性能。研究结果发现平均响应时间随任务到达率和运算量的增加而增加,随网络传输率的增加而减少;运算量和网络传输速度是影响系统平均响应时间的瓶颈。因此,提出的模型对实用的三值光学计算机任务管理系统的设计具有指导意义。

Quality of Service（QoS） is a crucial factor for the commercial success of a ternary optical computer（TOC）. This paper presents a task scheduling model for TOC based on first-come-first-service strategy, the M/M/1 queuing system and tandem queueing. And it uses the mean response time to analyze and evaluate the performance of TOC. The results demonstrate that the computation and network transmission speed is the bottleneck of system average response time. Therefore, the presented model is good for designing the task management systems of TOC.
