SIMD Extension to C++ OpenMP in Visual Studio

March 27, 2019 Mar 27, 2019 03/27/19

Hongtao Yu

In the era of ubiquitous AI applications there is an emerging demand of the compiler accelerating computation-intensive machine-learning code for existing hardware. Such code usually does mathematical computation like matrix transformation and manipulation and it is usually in the form of loops. The SIMD extension of OpenMP provides users an ...
