New week, new Rust! What are you folks up to?
I'm working on apis-saltans.
Improving performance of my GPU-based physics simulation. Since my previous post, a lot of time has passed and a lot has changed. Now my sim has collisions, parameters configurable via env vars, performance is much better, the code is cleaner, and README is actually useful.
I decided to focus on performance instead of features, because there is still a lot of relatively low hanging fruit. For example, in the past 2 days, I managed to improve performance by 40% just by replacing a shader with a hardware supported buffer clear command (-225 lines of code) and implementing a few easy optimizations. Now it can comfortably simulate 256k particles on Radeon RX 560 at 30 FPS, and I suspect that a million might be possible.
So that's what I'm doing this week — squeezing everything I can from my RX 560.
