看一下UNIX系统中的进程和Mach的任务和线程之间的关系。在UNIX系统中,一个进程包括一个可执行的程序和一系列的资源,例如文件描述符表和地址空间。在Mach中,一个任务仅包括一系列的资源;线程处理所有的可执行代码。一个Mach的任务可以有任意数目的线程和它相关,同时每个线程必须和某个任务相关。和某一个给定的任务相关的所有线程都共享任务的资源。这样,一个线程就是一个程序计数器、一个堆栈和一系列的寄存器。所有需要使用的数据结构都属于任务。一个UNIX系统中的进程在Mach中对应于一个任务和一个单独的线程。
-look at the UNIX System and the process of Mach"s mandate and the relationship between the threads. In UNIX systems, a process includes an executable program and a range of resources, such as file descriptors table and address space. In Mach, a task only a series of resources; Threads handle all the executable code. A Mach task can have any number of threads and its associated, and each one must thread related tasks. And to a certain set of tasks related to the threads are sharing all the resources. Thus, a thread is a program counter, a stack, and a series of registers. All need to use the data structures are covered by the mandate. A UNIX system in the process of Mach which corresponds to a mandate and a separate thread.

程序用C++模拟了操作系统中的三种最典型的简单的静态进程调度算法;先由用户动态输入生成模拟进程,使用了26种可供用户选择的典型语句(包括循环、选择结构),可处理整型、布尔型与字符型三种数据与表达式计算;程序编制时主要采用的编程技术是:用语句链表记录进程语句,并用PCB链表,就绪队列链表,阻塞队列链表,执行队列链表,结束队列链表等数据表示进程处理过程中的相互关系,由于静态数据结构不适合处理数据量大小不定的数据,而动态队列结构适合于处理数据量大小可变数据的处理,因此在程序中采用动态链表对这些数据进行处理;使用信号量、P.V.操作实现进程的同步与互斥,模拟进程在操作系统中的运行-procedures C to simulate the operating system, the three most typical process simple static scheduling algorithm; First generation user input dynamic modeling process, the use of the 26 options are available to users of typical statement (including the circle, choose structure), can handle integer, boolean and three character expression data and calculation; the main procedures for the preparation of the programming technology : Listless statement recorded statement process, and PCB Chain, ready Queue List, blocking Queue List, the Executive Queue List, ending Queue List data processing, said the process of mutual relations, due to static state data structure is not suitable for handling data on the s
