Domain-specific compilers that generate explicit SIMD code from a high-level specification are even nicer. These can fully exploit the capabilities of the instruction set (e.g., fast permutes, masking, reduced precision floats, large register file, etc.) for a particular domain For example, generating AVX-512 code for convnet inference: https://NN-512.com https://NN-512.com NN-512 does four simultaneous 8x8 Winograd tiles (forward and backward) in the large AVX-512 register file, accelerates strided convolutions by interleaving Fourier transforms (again, with knowledge of the large register file), makes heavy use of the two input VPERMI2PS permutation instructions, generates simplified code with precomputed masks around tensor edges, uses irregular/arbitrary tiling patterns, etc. It generates code like this: https://nn-512.com/example/11 https://nn-512.com/example/11 This kind of compiler can be written for any important domain
