Compared to VS2015 Update 3, VS2017 15.5 provides on average an 8.9% increase in runtime speed in the SPEC 2017 benchmark (for detailed numbers see slid...

The Parallel Programming in Native Code blog recently announced Clang support for C++ AMP via LLVM backend. This is a key milestone in our commitment (as mentioned in Somasegar's blog) to share the C++ AMP specification to all C++ developers, regardless of whether they're using Visual C++ or not. Portability across hardware and platforms is one of ...

If you have arrived in the middle of this blog series, you might want instead to begin at the beginning. This post explains the flow of data within the Visual C++ compiler – starting with our C++ source program, and ending with a corresponding binary program. This post is an easy one – dipping our toes into the shallow end of ocea...
