页面调度算法
页式虚拟存储器的页面置换算法一般有: 最佳置换算法(OPT),先进先出置换算法(FIFO),最近最久未使用置换算法(LRU),Clock置换算法,最少使用置换算法(LFU),页面缓存算法(PBA)等。 先进先出(FIFO)置换算法是最直观的置换算法,由于它可能是性能最差的算法,故实际应用极少。在这里我只使用前面三种算法来进行页面调度(Page replacement algorithms for page virtual memory generally include the best permutation algorithm (OPT), advanced first out permutation (FIFO), the most recent unused replacement algorithm (LRU), Clock permutation algorithm, minimum use of permutation (LFU), and page caching algorithm (PBA). The first in first out (FIFO) replacement algorithm is the most intuitive replacement algorithm, because it may be the worst performing algorithm, so there are few practical applications. Here I only use the first three algorithms for page scheduling.)

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

clock页面置换算法
clock页面置换算法
用CLOCK置换算法仿真请求分页系统
1、设计目的:用高级语言编写和调试一个内存分配程序,加深对内存分配算法的理解。
2、设计要求:
1) 实现请求分页存储管理方式的页面置换算法:CLOCK算法
2) 内存物理块数固定为15个,对多个作业采用可变分配全局置换的策略分配物理块
3) 作业数量与作业大小(10-20页)可在界面进行设置
4) 所有作业按RR算法进行调度,时间片长度为1秒
5) 可为每个作业随机产生引用的页面串,也可以人工输入引用的页面串,页面串长度50---100,要求必须包括作业所有的页面,可作为样例数据保存
6) 可读取样例数据(要求存放在外部文件中)进行作业数量、作业大小、页面串长度的初始化
7) 要求采用可视化界面,模拟内存分配和使用情况图,可在运行过程中随时暂停,查看当前内存物理块使用情况。
8) 每次全部作业运行结束后,要求打印出访问命中率 (clock page replacement algorithm)

banker_by_array
说明: 本程序为自己在学习操作系统时独立根据书上所述的银行家算法制作而成,包括一个数组输入函数(Sr()),数组输出函数(Pr())和一个判断函数(test()),并通过指针传递参数,可以自定义进程数目和资源种类数目(源程序限10个以内,可自行更改数组)。
注:本程序是在linux环境下通过gcc编译器编译成功的。若移植到windows环境下可能在汉字显示部分出现乱码。(This procedure for their own independence in learning, when the operating system on the basis of the book described in banker s algorithm produced, including an array of input function (Sr ()), array output function (Pr ()) and a judging function (test () ), and through pointer parameters, the process can customize the number and type of the number of resources (source 10 within limits, can make changes to the array). Note: This procedure is in the linux environment through the gcc compiler to compile successful. If transplanted into windows environment may display garbled characters.)
