设计一个有N个进程并发的进程调度程序。
进程调度算法：采用最高优先数优先的调度算法（即把处理机分配给优先数最高的进程）算法。
-Design of a concurrent process, N a process scheduler. The process of scheduling algorithm: The number of priority the highest priority scheduling algorithm (ie the number of processors allocated to the highest priority to the process) algorithm.
