Fly.exe is a neural simulator that runs a complete male fruit fly brain connectome (165,122 neurons and 25.5 million synaptic connections) in a physics-based virtual environment on a single GPU. Twelve simulated flies with embodied neural circuits navigate a virtual arena with food and obstacles, demonstrating goal-directed behavior driven purely by their connectome-based neural networks without explicit steering rules.
soup-connectome is a portable runtime for executing the fruit-fly connectome across CPU, CUDA, WebGPU, and WASM using sparse graph streaming and deterministic LIF neuron semantics. The project converts MaleCNS connectome data (211,577 neurons, 24.7M edges) into portable .scx artifacts and demonstrates reproducible execution across multiple backends with explicit device planning.
