OS Scheduler

Course: CPE 473: Operating Systems
Institution: Jordan University of Science and Technology
Department: Computer Engineering

Assignment Overview

In this assignment, you will implement a simple OS Scheduler using C/C++. The scheduler will:

1. Receive a set of processes and their details.
2. Decide the order of execution based on the Ranking Scheduling Algorithm.
3. Output the process execution order along with some statistics for each process.

Scheduler Details

Input Format

The input file (in.txt) contains:

1. An integer N (number of processes).
2. N lines with the following format for each process:
   • A string s: Process name (can contain multiple characters).
   • Three numbers:
     1. Arrival Time
     2. Processing Time
     3. Rank

Each value is separated by a tab (\t). Input values can go up to 100,000,000.

Ranking Scheduling Algorithm

1. Processes with lower rank values get higher priority.
2. For processes with the same rank:
   • Choose the one with the earlier arrival time.
3. If rank and arrival time are identical:
   • Choose the process that appears first in the input.

Output Format

Write the output to a file (out.txt) with:

1. One line per process in the execution order, showing:
   • Process Name
   • Response Time
   • Turnaround Time
   • Delay
2. A final line showing the execution order of the processes.
