Use fixed-size and native SIMD types, masks, permutations, reductions, and math operations with ABI stability.

Write vectorization-friendly loops, use pragmas and attributes, analyse optimization reports, and fix missed opportunities.

Write architecture-specific kernels with intrinsics, dispatch at runtime with cpuid, and maintain portable fallbacks.

Offload parallel kernels to GPUs with SYCL (oneAPI) or OpenMP target, manage unified memory, and interop with CUDA.
