Operating System Scheduler

This project extends the functionality of the OS Scheduler to include advanced CPU scheduling algorithms and dynamic memory allocation, providing a comprehensive simulation of an operating system. The implementation showcases strong proficiency in C programming, emphasizing intricate algorithmic design and effective data structure utilization for both CPU and memory management.

Features

CPU Scheduling Algorithms:

  • Non-preemptive Highest Priority First (HPF).
  • Shortest Remaining Time Next (SRTN).
  • Round Robin (RR).

Memory Allocation Policies:

  • First Fit.
  • Buddy Memory Allocation.

Simulation Components:

  1. Process Generator: Simulates process creation, reads input files, and initiates scheduler and clock processes.
  2. Clock Module: Emulates an integer time clock.
  3. Scheduler: Core component managing processes, states, and execution based on scheduling algorithms.
  4. Process: Represents CPU-bound processes and notifies the scheduler upon termination.

How to Use

Compilation:

Compile the source files using your preferred C compiler.

Execution:

Run the compiled executable.

Input:

Provide process details in the processes.txt file.

Output:

Review the generated output files (scheduler.log, scheduler.perf, memory.log) for detailed simulation results.
