> he said that it's the most advanced language today when it comes to optimisation. Don't know if that still applies. I wrote quite a lot of HPC-like code lately. Can confirm. The reasons include first-party support for hardware intrinsics on all platforms (SIMD is the most important, but also scalar stuff like popcnt, pdep/pext, etc.), full control over RAM layout which allows to optimize data structures for cache friendliness, and the ecosystem of high-quality third party libraries.
