Take process Id or name from user

The solver solves the problem with the default process name (A B C ...). It will be very helpful if it can also take user input for process name or id.

I want to contribute to this project but I am having trouble in finding the code section where the main logic to calculate various values such as TAT, WT is written. I am a newbie to open source so may anyone please help me finding that code section ?
Thank you for your kind consideration.
