Memory Management Policies Simulator

Requirements

This simulation requires:

1. Python 2 or 3
2. sortedcontainers library of Python

sortedcontainers can be installed using pip install sortedcontainers or pip install -r requirements.txt

How to run

Simulation can be run via command line providing some flags. Here is the man page of main.py:

usage: main.py [-h] -s N -w FILE -p N -o FILE

Memory Management Policy Simulator

optional arguments:
  -h, --help            show this help message and exit
  -s N, --size N        memory size in Kb
  -w FILE, --workload FILE
                        path of workload file
  -p N, --policy N      memory management policy 1- VSP 2- PAG 3- SEG
  -o FILE, --output FILE
                        path of output report file

Note that -p flag donates the policy to use from the given options <1,2,3>. If policy 1 or 3 are chosen -a (algorithm) flag is must to provide from options of <1,2> where 1 and 2 represent first-fit or best-fit algorithms respectively. Otherwise, if policy number 2 is chosen -f(frame) flag is must to provide to indicate the frame size.

Few example run commands are also provided below.
