Rust SIMD Just Came to the GPU — and It Changes How We Think About Parallel Programming

For decades, GPU programming has meant one of two things: writing CUDA kernels in C++ or wrestling with OpenCL. Both require you to think in a fundamentally different paradigm than CPU programming. But VectorWare just changed that by making Rust's portable SIMD — core::simd — work natively on the GPU. If that sounds like a niche technical achievement, it isn't. It's the first crack in a wall that has separated CPU and GPU programming for twenty years. The Problem: Two Worlds of Parall
