先来先服务（FCFS）算法、短作业优先（SJF）算法、高响应比（HRN）算法和高优先权优先算法是作业调度中经常采用的，通过上述算法的模拟加深对作业控制快JCB的理解和作业调度过程的实现技巧-job jobjob jobjob jobjob jobjob jobjob jobjob jobjob jobjob job

此为操作系统实验报告:处理器调度 内含:程序流程图 设计目的与思路 主要源码等. 简介:在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态。当就绪状态进程个数大于处理器数时，就必须依照某种策略来决定哪些进程优先占用处理器。本实验模拟在单处理器情况下处理器调度，帮助学生加深了解处理器调度的工作。-experimental operating system for this report : Processor Scheduling consisting of : flowchart designed and ideas such as major source. Introduction : the introduction of multi-channel programming system, often there are a number of processes at the same time readiness. When the readiness of the process is greater than the number when the number of processors, it must, in accordance with a strategy to determine which process priority processor. Experimental simulation of the processor in a single processor scheduling circumstances, to help students better understand processor scheduling work.

实时动态显示进程信息的程序，如资源利用等。比任务管理器显示更多进程信息- Real-time dynamic demonstration advancement information procedure, like resources use and so on. Compared to the task management demonstration are more advancements information

一个多线程编程源码-A multi-threaded programming source

进程管理，动态分配内存，按照最大优先级的动态分配-process management, dynamic memory allocation, in accordance with the priority of the largest dynamic allocation

简单线程计数器： 一个为直接输出无间隔，一个是有时间间隔输出-Counter easy thread: one for direct output without partitions, there is a time interval are output

一个多任务应用程序。带有四个彩色转轮的应用程序，每个彩色转轮都按自己的线程运行。其中两个使用OnIdle函数；另外两个则作为独立的线程运行。-a multi-tasking applications. Color wheel with four applications, each color wheel has its own threads to run. Two of them use OnIdle function; The other two were used as the independent threads running.

使CPU利用率为100％ 当为双核是运行两个实例即可-So that CPU utilization was 100 when running for the dual-core is two examples can be

线程怎么通信,这里有解释.线程就是操作系统分配给处理器的基本单元.系统为没一个线程分配一个堆栈-threads how communications, explained here. The operating system is threaded processors allocated to the basic unit. No one system to allocate a thread stack
