I. Project Organization
This project demonstrate six different scheduling algorithms.
You should do the following pieces to complete your project. Each piece is explained below:
• Code 60 points
• Output 30 points
• Summary 10 points
Code
Your code should be nicely formatted with plenty of comments. The code should be easy to read,
properly indented, employ good naming standards, good structure, etc.
Output
Output will be graded by running your program. Each algorithm’s output is 5 points.
Summary
The summary section should discuss your project experience. You should discuss how you approached
the project, including anything difficult or interesting, what was learned, and the end result. This should
be at least 1 page in length.
II. Project Description
Language/Platform/Approach
This project must target a Unix platform and execute properly on our CS1 server.
The project must be written in C, C++, or Java.
Problem Overview
This project will simulate a scheduler scheduling a set of jobs.
The project will allow the user to choose a scheduling algorithm from among the six presented in the
textbook. It will output a representation of how the jobs are executed.
Design
You may design your own implementation approach, but here are a few constraints.
Your program should read in a list of jobs from a tab-delimited text file named jobs.txt. The format of the
text file should have one line for each job, where each line has a job name, a start time and a duration. The
job name must be a letter from A-Z. The first job should be named A, and the remaining jobs should be
named sequentially following the alphabet, so if there are five jobs, they are named A-E. The arrival times
of these jobs should be in order.
The scheduler choice should be a command-line parameter that is one of the following: FCFS, RR, SPN,
SRT, HRRN, FB, ALL. If ALL is input, the program should produce output for all six scheduling
algorithms. RR and FB should use a quantum of one. FB should use three queues.
Your output should be a graph as shown in the slides. The graph can be text or you can use a graphics
package such as JavaFX to draw the graph. For text, you may draw the graph down the page rather than
across.
Your program should be able to reproduce the sample shown in the book as well as any similar set of jobs.
Sample Output
Below is sample text-based output. For graphical output, you can make the graph look like the ones in the
textbook and slides.

A XXX
B XXXXXX
C XXXX
D XXXXX
E XX

III. Project Guidelines
Submitting
Submit your project on eLearning. Include in your submission the following files:
1) readme.txt. A readme file describing how to compile and run your project
2) summary.doc A Word document for the summary
3) Your source files
Academic Honesty
All work must be your own. If cheating is suspected, you will be referred to the Judicial Affairs Office for
further discussion. Copying may be detected in a number of ways, including by software which compares
your code with all other students’ source code, by comparison with code on the Internet, or by a visual
inspection of your source code.
Resources
The slides and textbook describe the six algorithms to be used.
