An event-driven queue simulator originally written for CMU 15-259 (Probability and Computing), CMU 15-857 (Analytical Performance Modeling and Design of Computer Systems), and later extended with a C++ backend and more configurations.

This tool lets users represent networks and systems with queues abstractly and run an event-driven simulation to gather statistics on response times and queueing delays.

In queueing terms, the simulator currently supports G/G/k with FCFS, PS, and SRPT scheduling, as well as Jackson networks. Policies and distributions are extensible in both Python and C++.
