现代OS中的进程调度仿真设计与实现

Design and Realization of the Simulation of Process Scheduling At Modern OS is Inside

采用模拟与仿真思路,以定时器驱动机制为模式,用动画方式,以进程调度为中心,实现了对选用调度算法的运行过程的模拟与仿真,同时也实现了进程创建、调度、执行、阻塞和终止过程的可视化.系统能够自动完成进程演进过程的数据记录和分析,并对算法的性能进行初步评测.这对深入理解操作系统核心层,透析进程原理,发现和研究新的调度算法具有重要意义.

Uses the simulation and emulation mentality, takes the timer as the actuation mechanism, with the animation way, takes the Process Scheduling as center, the system has realized the simulation and emulation of movement process of five kind of Scheduling Algorithms, at the same time, realized the visualization of the Process of Process Creating, Scheduling, Executing, Blocking and Terminating. The system can automatically complete the recording and analyzing of advancement evolution process data. Under the identical condition, the system can take the histogram as a form, carry on the comparative evaluation and analysis to the capability of correlative Scheduling Algorithm, the effect is direct-viewing. This has the vital significance to catch on the kernel layer of operating system, to dialyse process principle, to discover and study the new Scheduling Algorithm.
