Also for CPUs there is ispc (https://ispc.github.io/ https://ispc.github.io/) which provides a language that takes advantage of modern CPU's parallel friendly features with a C-like syntax. From the site: > ispc compiles a C-based SPMD programming language to run on the SIMD units of CPUs and the Intel Xeon Phi™ architecture; it frequently provides a 3x or more speedup on CPUs with 4-wide vector SSE units and 5x-6x on CPUs with 8-wide AVX vector units, without any of the difficulty of writing intrinsics code. Parallelization across multiple cores is also supported by ispc, making it possible to write programs that achieve performance improvement that scales by both number of cores and vector unit size. There is also an interesting story of its development (full with office politics drama :-P) written by its -then- main developer: https://pharr.org/matt/blog/2018/04/18/ispc-origins.html https://pharr.org/matt/blog/2018/04/18/ispc-origins.html
