通过研究Linux的线程机制和信号量实现读者写者(Reader-Writer)问题并发控制。 1)写-写互斥：不能有两个写者同时进行写操作； 2）读-写互斥：不能同时有一个线程在读，而另一个线程在写； 3）读-读允许：可以有一个或多个读者在读； 4）读者优先的附加限制：如果读者申请进行读操作时已有另一个读者正在进行读操作，则该读者可直接开始读操作； 5）写者优先的附加限制：如果一个读者申请进行读操作时已有另一个写者在等待访问共享资源，则该读者必须等到没有写者处于等待状态后才能开始读操作。 -By studying the Linux thread mechanism and semaphores realize readers who write (Reader-Writer) the issue of concurrency control. 1) to write- write mutex: Can not write at the same time there are two write operations 2) read- write mutex: Can not have a thread at the same time in reading and writing another thread 3) Reading- Reading of permit: can have one or more readers read 4) the priority of additional restrictions readers: If the readers apply for a read operation, there was another reader being read, the reader can be directly started reading operation 5) to write additional priority Restrictions: If an application for a reader reading write operation has been in waiting for another visit to a shared resource, the read

实现了几种内存页面置换算法，有最佳置换算法和先进先出置换算法，还有LRU置换算法。-To achieve a number of memory page replacement algorithm, the best replacement algorithm and FIFO replacement algorithm, as well as LRU replacement algorithm.

磁盘调度算法 1。实现三种算法： 1。先来先服务 2。最短寻道优先（可自己假设当前磁头的位置） 3。电梯算法 2。磁道服务顺序从指定的文本文件（TXT文件）中取出 3。输出： 第一行：磁道的服务顺序 第二行：显示移动总道数-a disk scheduling algorithms. Three algorithms to achieve : 1. First-come first-serve two. Seeking shortest priority (to be their head the assumption that the current location) 3. Elevator Algorithm 2. Track services from the designated order of the text document (TXT) out of three. Output : the first line : track the order of the second line services : Road show that the total number of mobile
