Hi all, Don't know if many people noticed this, but this looks like a handy new feature for glibc to get (from the release announcement):
https://www.sourceware.org/ml/libc-alpha/2015-08/msg00609.html #* Added vector math library named libmvec with the following vectorized # x86_64 implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, # exp, expf, pow, powf. More info on the glibc website: https://sourceware.org/glibc/wiki/libmvec # Libmvec is vector math library added in Glibc 2.22. # # Vector math library was added to support SIMD constructs of OpenMP4.0 # (#2.8 in http://www.openmp.org/mp-documents/OpenMP4.0.0.pdf) by # adding vector implementations of vector math functions. # # Vector math functions are vector variants of corresponding scalar math # operations implemented using SIMD ISA extensions (e.g. SSE or AVX for # x86_64). They take packed vector arguments, perform the operation on # each element of the packed vector argument, and return a packed vector # result. Using vector math functions is faster than repeatedly calling the # scalar math routines.
