CPU Scheduling Algorithms

Practicing OS fundamentals by re-creating the following CPU scheduling algorithms:

• Round Robin
• Shortest Job First
• Priority Scheduling (No Preemption)
• Priority Scheduling (Preemption)

Code will output the algorithm used, waiting time for all processes, and the overall average waiting time.

Compile

g++ src/main.cpp -o bin/main

Run Specific Input (Default)

Ensure lines 432 and 433 are the following:

// return !testAlgorithms(16);
return generateOutput();

Then run the following command after compiling

bin/main <input_file.txt>

Will write the output to an output.txt file.

Run All Test Cases

Change lines 432 and 433 to the following:

return !testAlgorithms(16);
// return generateOutput();

Then run the following command after compiling

bin/main

Will display output to the terminal.
