kvm-9
DL : 0
KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware. It consists of a loadable kernel module (kvm.ko) and a userspace component. Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc. The kernel component of KVM is included in mainline Linux, and will appear in Linux 2.6.20. KVM is open source software. -KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware.

exmap-0.9
DL : 0
内存管理工具Exmap。该工具比 ps 或 top 更精确,因为它考虑了多个应用程序使用的共享库。例如,如果两个应用程序使用了相同的共享库,各占 1MB 内存,ps 会显示这两个应用程序均额外使用了 1MB 内存,exmap 则能更准确地显示每个应用程序都只使用了 500 KB 内存。这种精确性对于评价 KDE 和 GNOME 之类的桌面环境非常重要,因为在这些情况下应用程序之间会大量使用共享库。-Memory management tools Exmap. The tool than the ps or top more accurate because it takes into account multiple applications use shared libraries. For example, if both applications use the same shared library, each with 1MB of memory, ps will display these two applications are the use of additional 1MB of memory, exmap can more accurately show that each application only uses the 500 KB of memory. This evaluation of the accuracy of the KDE and GNOME desktop environment, such as very important, because in these circumstances the application will be between the large-scale use of shared libraries.

(1)用C语言来实现对N个进程采用动态优先权优先算法的进程调度; (2)每个用来标识进程的进程控制块PCB用结构来描述,包括以下字段: 进程标识数id; 进程优先数priority,并规定优先数愈大的进程,其优先权越高; 进程已占用的CPU时间cputime 进程还需占用的CPU时间alltime,当进程运行完毕时,alltime变为0; 进程的阻塞时间startblock,表示当进程在运行startblock个时间片后,进程将进入阻塞状态; 进程被阻塞的时间blocktime,表示已阻塞的进程再等待blocktime个时间片后,将转换成就绪态; 进程状态state 队列指针next,用来将PCB排成队列。 (3)优先数改变的原则: 进程在就绪队列中呆一个时间片,优先数增加1. 进程每运行一个时间片,优先数减3. (4)假设在调度前,系统中有5个继承,它们的厨师状态如下: ID 0 1 2 3 4 PRIORITY 9 38 30 29 0 CPUTIME 0 0 0 0 0 ALLTIME 3 3 6 3 4 STARTBLOCK 2 -1 -1 -1 -1 BLOCKTIME 3 0 0 0 0 STATE READY READY READY READY READY -(1) using C language to implement a process of N priority scheduling algorithm with dynamic priority of the process of scheduling (2) Each of the process used to identify the process control block PCB used to describe the structure, including the following fields: Process ID number id The process priority number priority, and provides greater process priority number, the higher its priority Process has occupied the CPU time, cputime The process needs to take up the CPU time of alltime, when the process has finished running time, alltime becomes 0 The process of blocking time startblock, said that when the process is running startblock a time slice, the process will enter the blocked state Processes are blocked time blocktime, indicated that they had blocked the process of time to wait blocktime films, will be converted into a ready state Process status state Queue pointer next, is used to PCB arranged in the queue.

从0-9中任意选取4个不完全相同的数 比如,不能是5 5 5 5,可以是1 2 2 2 用这4个数排列出最大的数,2221,最小的数1222 最大减最小:2221-1222=0999 用0 9 9 9这四个数继续重复上述步骤 最多7步,将得到6174这个数字 -From 0-9 in the arbitrarily selected four non-identical number, for example, can not be 5555, which can be 1222 used the number 4 ranked the greatest number, 2221, the smallest number of 1222 maximum minus minimum: 2221-1222 = 0999 by 0999 the number of these four to continue to repeat the above steps up to 7 steps, this number will be 6174

利用LRU算法仿真请求页面系统 1、设计内容: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:近期最久未使用算法(LRU) 2) 内存物理块数固定为3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(0-9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 -Request page using LRU algorithm simulation system

1.在内存中开辟一个虚拟磁盘空间作为文件存储器,在其上实现一个多用户多目录的文件系统。 2.文件物理结构可采用显式链接或其他方法。 3.磁盘空闲空间的管理可选择位示图或其他方法。如果采用位示图来管理文件存储空间,并采用显式链接分配方式,则可以将位示图合并到FAT中。 4.文件目录结构采用多用户多级目录结构,每个目录项包含文件名、物理地址、长度等信息,还可以通过目录项实现对文件的读和写的保护。目录组织方式可以不使用索引结点的方式,但使用索引结点,则难度系数为1.2。 5.设计一个较实用的用户界面,方便用户使用。要求提供以下相关文件操作: (1)具有login (用户登录) (2)系统初始化(建文件卷、提供登录模块) (3)文件的创建: create (4)文件的打开:open (5)文件的读:read (6)文件的写:write (7)文件关闭:close (8)删除文件:delete (9)创建目录(建立子目录):mkdir (10)改变当前目录:cd (11)列出文件目录:dir (12)退出:logout 6.系统必须可实际演示,选用程序设计语言:C++、C等。 -multiple directory files system
