![]() ![]() ![]() ![]() The vectorization is not guaranteed, and loops annotated but not vectorized will get a warning reported. This allows loops annotated with “#pragma omp simd” to potentially be vectorized. This can be turned on with a new CL switch -openmp:experimental. Our case study is the Intel MKL-DNN library, which is used as a building block for other well-known open source ML libraries including Tensor Flow. Added basic support for OpenMP SIMD vectorization which is the most widely used OpenMP feature in machine learning (ML) libraries.If you find the compiler is under-inlining, consider passing -O2 -Ob3. O2 (optimize the binary for speed) still implies -Ob2 by default, but this may change in the future. Ob3 is a more aggressive version of -Ob2. Added a new inlining command line switch: -Ob3.In Visual Studio 2019 Preview 2 we have continued to improve the C++ backend with new features, new and improved optimizations, build throughput improvements, and quality of life changes. ![]()
