cpu-scheduler

A simple discrete discrete-time event simulator for a number of CPU schedulers on a single CPU system.

Dependencies

• Python 3
• Pandas
• Matplotlib
• Others, see requirements.txt

The dependencies take a while to install, (especially Pandas) so just be patient during first time setup.

Usage

Run with default configuration:

$ source run.sh
Sim running, please be patient
Sim done, execution time: 168.723174
Plot is at data/1541391135/plots/plot.png
$ open data/1541391135/plots/plot.png

Advanced usage:

$ python3 -m venv env
$ source env/bin/activate
$ pip install -r requirements.txt
$ python main.py <LENGTH> <MAX_RATE> <BASE_SEED>
Sim running, please be patient
Sim done, execution time: 168.723174
Plot is at data/1541391135/plots/plot.png
$ deactivate
$ open data/1541391135/plots/plot.png

Where:

• LENGTH: The number of processes to simulate
• MAX_RATE: From 1 to MAX_RATE processes per second arrival will be simulated, so if MAX_RATE equals 30, 30 different simulations will be run for each schedule type
• BASE_SEED: The base seed for the pseudo-random number generator. Simulations of the same rate will have the same base seed for comparision purposes
