5.1. Exercises
- Learning Objectives
An understanding of
event-driven systems
state diagrams
modeling event-driven systems with TLA+
- Description
The goal is to model a river crossing puzzle as an event-driven system using TLA+.
You may work on the wolf, goat, and cabbage puzzle, or another puzzle from this page, or you can suggest some other, similar puzzle.
- Submission
Each individual student who participated in the activity should submit a screenshot of their work completed by the end of the session.
- Learning Objectives
An understanding of
concurrent systems
bounded buffers with multiple producers and consumers (MPMC)
- Description
The goal is to model a system with a single, shared bounded buffer and multiple producers and consumers.
The producers are workstations submitting print jobs to the shared print queue (buffer).
The consumers are printers removing print jobs from the shared print queue.
The shared print queue is a fixed-size, circular, array-based buffer as described in this lab.
For now, we’ll hard-code the number of instances of producers and consumers, respectively.
We will also define the number of jobs each workstation submits to range over various values so that we’ll get many combinations.
Finally, we’ll define suitable temporal properties, e.g.
termination: the print queue should eventually be empty
eventual consistency: at the end, the total job count should be equal to the sum of the initial number of jobs each workstation was going to submit
