The myscheduler is the program which calculates the total time for all of the processes to be completed and prioritises the processes on which needs the least time to be completed.
Your understanding is pretty complete, other than the "prioritises the processes on which needs the least time to be completed", so I'm unsure why you describe things as "can't make heads or tails of this project"?? I don't believe it's the sort of thing that can be described in much simpler terms, other than "we're emulating a 5-state pre-emptive scheduling model that is configured by attributes in 2 input files". Many of the concepts/factors you've identified in your 2nd paragraph are defined in more detail in lectures and the recommended reading.

You should experiment with your sysconfig and commands files to test each of the (6) system-calls, and different sleeping and I/O timings that permit multiple processes to be in the system and each making progress towards their termination.
