# QUESTIONS: 9-Scheduling-Lottery This program, **lottery.py**, allows you to see how a lottery scheduler works. See the README for details. ## Warmup 1. Compute the solutions for simulations with 3 jobs and random seeds of 1, 2, and 3. ## Questions 1. Now run with two specific jobs: each of length 10, but one (job 0) with just 1 ticket and the other (job 1) with 100 (e.g., `-l 10:1,10:100`). - What happens when the number of tickets is so imbalanced? - Will job 0 ever run before job 1 completes? How often? - In general, what does such a ticket imbalance do to the behavior of lottery scheduling? 1. When running with two jobs of length 100 and equal ticket allocations of 100 (`-l 100:100,100:100`), how unfair is the scheduler? Run with some different random seeds to determine the (probabilistic) answer; let unfairness be determined by how much earlier one job finishes than the other. 1. How does your answer to the previous question change as the quantum size (`-q`) gets larger? 1. Can you make a version of the graph that is found in the chapter? What else would be worth exploring? How would the graph look with a stride scheduler?
