distributionofstoragemanagementandrecovery
模拟段式存储管理的分配与回收,能够输入给定的内存大小,进程的个数,每个进程的段数及段大小;当某进程提出申请空间的大小后,显示能否满足申请,以及为该进程分配资源后有关内存空间使用的情况。
(Analog-stage distribution of storage management and recovery, be able to enter a given memory size, number of processes, each process segment number and segment size when a space the size of the application process, the show can meet the application, as well as the The process, after the allocation of resources relating to the use of memory space.)

Storage_Simulator0001
在采用多道程序设计的系统中,往往有若干个进程同时处于就绪状态。当就绪进程个数大于处理机数时,就必须依照某种策略来决定哪些进程优先占用处理机。本实验模拟在单处理机情况下的处理机调度,帮助学生加深了解处理机调度的工作。
二、实验类型
设计型。
三、预习内容
预习课本处理机调度有关内容,包括进程占用处理机的策略方法。
四、实验要求与提示
设计进程调度算法,进程数不定;包含几种调度算法,并加以实现;输出进程的调度过程——进程的状态、链表等。要求使用优先权法和轮转法模拟进程调度过程。
【提示】:简化假设
1) 进程为计算型的(无I/O)
2) 进程状态:ready、running、finish
3) 进程需要的CPU时间以时间片为单位确定
【提示】:算法描述
1) 优先权法——动态优先权,当前运行进程用完时间片后,其优先权减去一个常数。
2) 轮转法

file-management-experiment
操作系统文件管理实验:利用交互式命令实现树型目录结构和文件管理,同时利用位示图表示外存的分配情况,新建文件时分配必要的空间,模拟文件分配表记录文件在外存上的存储方式。了解系统对文件的操作。
在文件中保存目录内容,创建文件或子目录可以用命令行命令:MD、CD、RD、MK(创建文件)、DEL(删除文件)和DIR(Operating system file management experiment: the use of interactive command tree directory structure and file management, while taking advantage of the bit map indicates the distribution of the external memory, and allocate the necessary space when a new file is created, the simulation file allocation table log file is stored in the external memory way. Understanding of the system operation on the file. Save the contents of a directory in the file, create a file or subdirectory can use the command-line command: MD, CD, RD, MK (create a file), DEL (delete files) and DIR)

fptree
FP-growth算法的改进C++程序,具有较好的扩展性和应用性,本程序改成用行读取,然后在内存中解析。更有效的方式是采用块读取方式(本人在以前项目中验证过,速度大为提高。)(FP-growth algorithm C++ Procedures, have good scalability and application, the procedure changed to use line to read, and then resolve in memory. More effective approach is the use of block-read mode (I tested before the project, speed greatly improved.))
