Description:

This project is a simulator for a batch job scheduler. Initial jobs are read from a user-supplied input file, placed into the queue, and then scheduler is started. Jobs run by priority (-20 highest priorty to 19 lowest priority), then by shortest length. Users may halt the scheduler in order to add new jobs or alter the priority of an existing job.

Dependencies:

• adaptable_heap_priority_queue.py
• heap_priority_queue.py
• priority_queue_base.py
• Empty.py

Original:

• project3.py
• Scheduler.py

Requirements:

• Python 3
• sys module
• time module
• input csv of jobs

Run as:

$ python3 project3.py <input-job-listing> <sleep-time>

Operation:

• Ctrl-C once to pause scheduler. Prompts for entering new job or altering existing job follow.
• Ctrl-C twice to exit.

Output:

Running output on screen is name, priority and remaining length of current job. Halted scheduler prints table of all jobs.
