Sierra – A SIMD Extension for C++

• dragontamer 8y ago
  "Varying" datatypes demonstrates that this author is aware of ISPC. Which is good! ISPC is a very nice environment, and I'd love to see a C++ version of it! I haven't worked with Sierra yet, but the intro looks like they "get it". Its important to make If/Else statements compile down into mask instructions (or AVX perm instructions) automatically. That way CPU SIMD can actually compete against GPU SIMD. I'm not sure if a new data-type is the best way of doing things, but it seems workable. I really liked Microsoft's C++ AMP which built everything out of templates though: https://download.microsoft.com/download/4/0/E/40EA02D8-23A7-4BD2-AD3A-0BFFFB640F28/CppAMPLanguageAndProgrammingModel.pdf https://download.microsoft.com/download/4/0/E/40EA02D8-23A7-... C++ AMP was more for GPU programming, not for AVX. But still, its got the right idea... and I think it had an AVX-fallback mode.

    Microsoft seems to consider C++AMP has reached its exploratory goal and new language features should be achieved via the ongoing Parallelism TS instead.

  Last activity on github was 3 years ago. Seems the project is dead.

  Was hopeing this was related to AGI from Sierra On-Line.
