Simso Past | Paper

Prepared for students and instructors who need a quick‑reference guide to the most common exam material surrounding the SIMSO (Simple Multiprocessor Scheduling Simulator) tool. 1. What is SIMSO? | Feature | Description | |---------|-------------| | Purpose | A lightweight, open‑source Python‑based simulator used to model and evaluate real‑time scheduling algorithms on uniprocessor and multiprocessor platforms. | | Key Modules | simso.core (event engine), simso.scheduler (algorithm implementations), simso.visualizer (Gantt charts, statistics). | | Typical Use‑Cases | • Academic labs for Operating‑Systems / Real‑Time Systems courses. • Research prototyping of novel scheduling policies. • Benchmarking of task sets (periodic, aperiodic, sporadic). | | Supported Algorithms | Fixed‑Priority (Rate‑Monotonic, Deadline‑Monotonic), EDF, PFair, LLF, Global/Partitioned variants, custom user‑defined policies. | | Input/Output | • XML task‑set description (period, WCET, deadline, offset). • JSON configuration for platform (CPU count, speed‑scaling). • CSV/HTML reports, Gantt visualisations. |
