Description: 基于DOS的多任务系统的实现
1. 用C语言完成线程的创建和撤消，并按优先权加时间片轮转算法对多个线程进行调度；
2. 改变时间片的大小，观察结果的变化。思考：为什么时间片不能太小或太大；
3. 假设两个线程共用同一软件资源（如某一变量，或某一数据结构），请用记录型信号量来实现对它的互斥访问；
4. 假设有两个线程共享一个可存放5个整数的缓冲，一线程不停的计算1到50的平方，并将结果放入缓冲中，另一个线程不断的从缓冲中取出结果，并将他们打印出来，请用记录型信号量实现这一生产者和消费者的同步问题；
5. 实现消息缓冲通信，并于3，4中的简单通信进行比较；
6. 思考：在线程间进行消息缓冲通信时，若对消息队列的访问没有满足互斥要求，情况会怎么样？-DOS-based multi-tasking system in a. C language to complete the creation and thread lift Priority increase as time slice Web algorithm for multiple-thread scheduling; 2. change the timing of the unit size, The results change. Thoughts : Why not films too little time or too much; 3. Assuming two threads to share the same software resources (such as a variable, or a data structure), with record-volume signal to achieve its exclusive interviews. 4. Suppose two threads share a deposit of five integer buffer keep a thread of 1-50 calculating the square, and the results Add buffer, Another constant thread removed from the buffer, and print them out, Please record-volume signal achieve this producers and consumers synchronization; 5.

Description: 多线程编程可以使程序具有多条并发执行线索，就像日常工作中由多人同时合作完成一个任务。
2、线程：
（1）线程是指程序的一个指令执行序列，WIN32 平台支持多线程程序，允许程序中存在多个线程。
（2） 在单 CPU 系统中，系统把 CPU 的时间片按照调度算法分配给各个线程，因此各线程实际上是分时执行的，在多 CPU 的 Windows NT 系统中， 同一个程序的不同线程可以被分配到不同的 CPU 上去执行。
-Multithreaded programming can make the program execute concurrently with a number of clues, like the daily work of collaboration by the people while a task. 2, threads: (1) thread is a program instruction execution sequence, WIN32 platform supports multi-threaded program that allows multiple program threads. (2) in a single CPU system, the system according to the CPU time slice allocated to each thread scheduling algorithm, so the thread is actually sharing executive, in the Windows NT multi-CPU system, with a different program thread can be assigned to different CPU up implementation.

Description: 并行是指时间上的同时处理。并发是将程序分成多个线程分段执行，通过调度线程执行顺序，来实现多个程序对于用户来说是同时运行的，就像你可以听歌的同时修改文档一样。但具体到线程级别的话，这些线程实际上是线性执行的，只不过执行消耗的时间片实在太短，人感觉不出来，只是觉得两个程序都在正常运行。目前能算得上并行的话也就多核技术了，而且还得解决同步问题，只能说更加接近并行的概念。-Parallel processing is the same in time. Concurrency is staging a program into multiple threads, thread scheduling through the execution order to achieve multiple programs are running simultaneously for the user, just like you can listen to music at the same time modify documents. But specific to the thread level, these threads are actually linear execution, but execution elapsed time slice is too short, people do not feel it, just think both programs are running. Currently words can also be regarded as a parallel multi-core technology, and it had to solve the synchronization problem, only that closer parallel concept. Platform: |
