OS Scheduler

This project simulates a CPU scheduler.

Implemented Algorithms

The scheduler component implements the following three scheduling algorithms:

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

Memory Allocation Algorithms

1. First Fit:

• Scans available memory blocks.
• Allocates the first block large enough for the process.

2. Buddy Memory Allocation:

• Divides total memory into powers-of-two blocks.
• Allocates the smallest available block for the process.
• Splits blocks into buddies if needed.
• Merges neighboring free blocks after de-allocation.

5. Input/Output:

• Input File (processes.txt)
• Output Files:
  • scheduler.log
  • scheduler.perf

How to Run

1. Compilation:

make

2. Execution:

make run
