Code optimization questions/recomendations (SIMD support, LLVM version) #31

Closed FFY00 closed 5 years ago

FFY00 commented 5 years ago

Hello, I am planning to user mir-glas for a project that needs to quickly process a huge amount of data. Binary compatibility across multiple systems is not an issue, so we are free to use SIMD instructions. How is SIMD implemented in mir-glas? Do I need to enable anything special? And while I'm on it, what LLVM is recommended for the most performance? Any other thing I should have in mind?

Thank you, Filipe

Hi Filipe, Mir GLAS isn't supported anymore (just because I don't have time to implement all features). You may want to use mir-blas (bindings to BLAS libraries like OpenBLAS or Intel MKL). See also the wiki page https://github.com/libmir/mir-lapack/wiki/Link-with-CBLAS-&-LAPACK
