🧾 Disco Engine
Disco Engine is a Python-based distributed discrete-event simulation core (“distributed simulation runtime”). It’s designed to run large, structured simulations (e.g., supply-chain / networked process models) by executing many independent NodeRuntimes that exchange events and promises over pluggable transports.
- Deterministic single-threaded stepping per worker process
- Scales out via multiple workers and transport backends
- Built for “engine + plugins” (models as Python packages)
Overview
At a high level, a Disco simulation is:
- a Layered Graph (scenario) that defines structure and data access,
- a Model plugin that defines simulation logic,
- an Experiment that defines parameters and run configuration,
- one or more Workers that host NodeRuntimes and step the simulation.
For local debugging and unit tests, Disco also includes a lightweight TestRun that executes a single, unpartitioned run without threading, metastore/cluster coordination, or external transports.
✨ Features
- Worker lifecycle & state machine for long-lived simulation processes
- Routing + transports (in-process, IPC, gRPC) for node-to-node delivery
- Partitioning to distribute nodes across workers (production), while keeping deterministic node order per worker
- TestRun for fast local runs without infrastructure (single-process, in-process transport only)
- Data logging via an optional
DataLogger
