Kernel Scheduling Simulator

A simulation for a mini operating system kernel implementing process scheduling algorithms (RR, HPF, SRTN).

Build

make

Usage

./os-sim -s <scheduling-algorithm> -f <processes-text-file> [-q <quantum>]

• <scheduling-algorithm>: rr, hpf, or srtn
• <processes-text-file>: Path to the process list file (e.g., processes.txt)
• -q <quantum>: (Optional) Quantum for RR scheduling

Example

./os-sim -s srtn -f processes.txt

Files

• os-sim: Main kernel simulator executable
• process: Simulated process executable
• processes.txt: Input file with process definitions

Notes

• The process generator spawns processes at their arrival times and sends them to the scheduler.
• The scheduler manages process execution according to the selected algorithm.
• See scheduler.log and scheduler.perf for logs and statistics after running.
