ReaxFF parameter optimization for β-Ga₂O₃ MD simulations using Gaussian process Bayesian optimization

Less than a year ago, Skydance Media closed its $8 billion merger with Paramount, making the Trump-friendly Ellison family—billionaire Oracle founder Larry and his son David, CEO of Paramount Skydance—among the most powerful media moguls in the country. A looming Paramount Skydance merger with Warner Bros. Discovery would expand their empire even further.

Many people reading this will call bullshit on the performance improvement metrics, and honestly, fair. I too thought the agents would stumble in hilarious ways trying, but they did not. To demonstrate that I am not bullshitting, I also decided to release a more simple Rust-with-Python-bindings project today: nndex, an in-memory vector “store” that is designed to retrieve the exact nearest neighbors as fast as possible (and has fast approximate NN too), and is now available open-sourced on GitHub. This leverages the dot product which is one of the simplest matrix ops and is therefore heavily optimized by existing libraries such as Python’s numpy…and yet after a few optimization passes, it tied numpy even though numpy leverages BLAS libraries for maximum mathematical performance. Naturally, I instructed Opus to also add support for BLAS with more optimization passes and it now is 1-5x numpy’s speed in the single-query case and much faster with batch prediction. 3 It’s so fast that even though I also added GPU support for testing, it’s mostly ineffective below 100k rows due to the GPU dispatch overhead being greater than the actual retrieval speed.
