Performance analysis and evaluation of ternary optical computer based on asynchronous multiple vacations

Ternary optical computer (TOC) has become a research hotspot in the field because of advantages such as inherent parallelism, numerous trits, low power consumption, extendibility, bitwise allocability and dynamical reconfigurability. Meanwhile, its performance evaluation attracts more attentions from potential users researchers. To model computing ecology accurately, this paper first builds three-staged TOC service by introducing asynchronous multi-vacations tandem queueing, then proposes task scheduling algorithm an processor allocation with vacations some small processors after dividing equally entire into several which can be used independently. At same time, analytical was established to obtain important indicators response number tasks utilization processor, based on M/M/1 M/M/n queuing system multi-vacations. In addition, relevant numerical simulation experiments are conducted. The results illustrate that processors, vacation rate allowed have effects performance. Compared synchronous vacation, not only ensures better maintenance but also improves degree.
