Running CUDA Code on Apple GPU with Minimal Kernel Changes

A CUDA/HIP‑based 3‑D fluid simulation was ported to an Apple M3 Pro device via a Clang‑HIP → SPIR‑V → Vulkan → MoltenVK conversion pipeline, achieving roughly ten‑fold speedup without any Metal‑specific API changes and preserving numerical accuracy.
