C++ wrappers for SIMD intrinsics.
xsimd is a library meant for SIMD (Single Instruction, Multiple Data) programming. It provides C++ wrappers for SIMD intrinsics and an implementation of common mathematical functions based on these wrappers. You can find out more about this implementation of C++ wrappers for SIMD intrinsics at the The C++ Scientist. The mathematical functions are a lightweight implementation of boost.SIMD.
xsimd requires a C++14 compliant compiler. The following C++ compilers are supported:
|Microsoft Visual Studio||MSVC 2015 update 2 and above|
|g++||4.9 and above|
|clang||3.7 and above|
The following SIMD instruction set extensions are supported:
|Architecture||Instruction set extensions|
|x86||SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, FMA3, AVX2|
|x86 AMD||same as above + SSE4A, FMA4, XOP|
