功能完整的瀑布墙视图效果，精选ios编程学习源码，很好的参考资料。(View full-featured waterfall wall effect, selection ios programming learning source, a good reference.)

1）设计一程序，由一个进程创建三个子进程，三个子进程一个是生产者进程，两个是消费者进程。 2）父子进程都使用父进程创建的共享存储区进行通信，由生产者进程将一个数组中的十个数值发送到由5个缓冲区组成的共享内存中。? 3）两个消费者进程轮流接收并输出这十个数值，同时将两个消费者进程读出的数值进行累加求各和。 4）考虑生产者进程生产的速度和消费者进程速度。(1) a program is designed to create three sub processes from one process, three sub processes is the producer process, and the two is the consumer process. 2) the father child process communicates with the shared storage area created by the parent process, and sends ten values in one array to the shared memory composed of 5 buffers by the producer process. L 3) the two consumer processes take turns to receive and output the ten values, and add values to each of the two consumer processes. 4) take into account the production speed of the producer process and the speed of the consumer process.)

操作系统课程设计。visual studio 2010,2008上的模拟UNIX文件系统的c++源码,附加实验报告和readmefile(1.Simulate a Unix file system on your Windows Platform 2.Understand the file system on Unix system, and the usage of i-nodes 3.Implement the function of sub-directory 4.The task needs to be completed using C++ or C 5.Allocate 16MB space in memory as the storage for your file system, the space is divided as blocks with block size 1KB 6.The i-node should support up to 10 direct block addresses, and should support at least one indirect block address )

操作系统的作业调度模拟,分享给大家学习用()

说明：  模拟操作系统经典生产者和消费者的原理代码(Simulated operating system, the principle of the classic producer and consumer code)

有界缓冲区内设有20个存储单元，放入/取出的数据项设定为1~20这20个整型数。 要求： (1)每个生产者和消费者对有界缓冲区进行操作后，即时显示有界缓冲区的全部内容.当前指针位置和生产者/消费者线程的标识符 (2)生产者和消费者各有两个以上 (3)多个生产者或多个消费者之间须共享对缓冲区进行操作的函数代码。">
