This repo contains my experiments with implementing N-Body simulations in Odin. The goal is to investigate the algorithms used and the approaches to optimization that are effective for them.

To run the demo:

odin run .

I recommend using the optimization flag speed: odin run . -o:speed

Also included in the src/utils.odin file are some benchmarking functions of varying usefulness. This should definitely be run with the speed optimization flag:

odin run ./src -o:speed

• Baseline
• SOA (?)
• Multi-threading
• SIMD
• Compute shader

• Baseline
• Particle Reordering
• Threaded force accumulation
• Threaded tree building (?)
• Compute Shader

The core functionality currently has no third party dependencies, but the basic visualization present in the main function relies on having my work in progress game framework/engine dial
