Task Management In The Monitor System Of The Ternary Optical Computer

The optical computer has much more data bits than the electrical computer because of the natural parallelism of light. Now an experiment system of Ternary Optical Computer (TOC), which has almost one thousand data bits, has been built in Shanghai University. In the future, the TOC will have more and more data bits. It is unreasonable that so many data bits are used by only one task in practice.On the other hand, Decrease-Radix Design Principle (DRDP) ensures that the TOC can reconfigure each operating units at different data bit segments of the optical processor (OP) at runtime, according to the users'requirement. Therefore, the OP can be employed as a complex processor, and the TOC can provide parallel computing for many operation requests of different users.This dissertation studies task management in the monitor system of the TOC which possesses thousand parallel data bits and one reconfigurable OP. A prototype and some kernel function modules of the monitor system are achieved in the thesis.The achievements of this paper can be summarized as follows:1) The architecture of TOC monitor system, including some kernel function modules and the communication protocols among them, is proposed.2) The time scheduling algorithm is implemented in the monitor system. And the fertures of the algorithm are analyzed in the thesis.3) An optical-processor-allocation-in-proportion algorithm is proposed.4) A prototype of task management in the TOC monitor system is implemented in Win32 assembly language. And the robustness, reliability and correctness of the monitor system are verified via a series of experiments.This paper is the first time to study the TOC monitor system. This study can enrich the basic theories on task scheduling and resource allocation. And the work sets up a theoretical foundation which will put the TOC into practical application as soon as possible.
