CSC227 — CPU Scheduler Simulation

A small Java simulation of CPU scheduling (SJF, Round Robin, Priority). The program reads jobs from job.txt, loads them into memory, and runs the chosen scheduler while printing statistics.

Build & Run

1. Compile sources to bin:

javac -d bin src/*.java

2. Run the program (keep job.txt in the project root):

java -cp bin Main

When running, the program will prompt to choose an algorithm:

• Enter 1 for SJF
• Enter 2 for Round Robin
• Enter 3 for Priority

Input

Place job.txt in the project root. The program's FileReaderTask reads that file to create jobs.

Project files (src)

• Main.java — program entry, starts FileReader, Loader, and Scheduler.
• FileReaderTask.java — reads job.txt into the job queue.
• LoaderTask.java — moves jobs into memory/ready queue.
• Scheduler.java — scheduling logic (SJF, RR, Priority).
• MemoryManager.java, PCB.java — memory and process control block utilities.

Notes

• Memory manager default size = 2048 (set in Main).
• The program uses simple console prompts; run in a terminal for interactive input.

Short and simple — update as needed.
