Udrasht / Page-replacement-policies-simulation

Implement page replacement policies like LRU, NFU, FIFO , Aging, Random etc . And also compare their results.

"PAGE REPLACEMENT POLICIES SIMULATION"

Requirements:

• C++ for compiling and running various page replacement algorithm
• Python3 for graph
• Matplotlib library for graph
• Install c++
• Bash shell to run project.sh script

		$ sudo apt install g++

• Install python

		$ sudo apt install python3

• Install Matplotlib

		$ python -m pip install -U matplotlib

Input Format

Each test case will be in three line First line contain number of frame Second line contain request page number stream.All the page number are space seperated Third line contain dirty Page Information

	Eample Testcase 1 :
	2
	7 0 1 2 0 3 0 4 2 3 0 3 2
	0 0 0 0 1 0 0 1 0 0 0 0 0

	Eample Testcase 2 :
	3
	7 0 1 2 0 3 0 4 2 3 0 3 2
	0 0 0 0 1 0 0 1 0 0 0 0 0

	Eample Testcase 3 :
	4
	7 0 1 2 0 3 0 4 2 3 0 3 2
	0 0 0 0 1 0 0 1 0 0 0 0 0

	Eample Testcase 4 :
	5
	7 0 1 2 0 3 0 4 2 3 0 3 2
	0 0 0 0 1 0 0 1 0 0 0 0 0

NOTE: Input is given with input.txt file

How To Run

• open terminal and execute project.sh file
• command

		./project.sh

• With the help of project.sh all the page replacement c++ file run and produce output in txt files which is use in python as input to draw graph between pagefault ratio and frame number

NOTE: All the temporary files will created during the execution and delete after the execution.

Output

• You see below result for individual page replacement algorithm.

• For Example:

    	Number of frame in MM: 2
    	Number of pages: 13
    	Number of page hit: 2
    	Number of page fault: 11
    	Page hit ratio : 0.153846
    	Page miss ratio: 0.846154
  

• Graph1 show individual page replacement algorithm between page fault ratio(y-axis) and number of frames(x-axis).

• Graph2 show individual page replacement algorithm between page hit ratio(y-axis) and number of frames(x-axis).
