C++ AMP on multicore CPU with SIMD

Question

I understand that a primary platform for C++ AMP is a GPU, but in many use cases multicore CPU with SIMD can be an attractive target as well. Does C++ AMP autovectorize to take advantage of SSE or AVX?

Answer 1

According to the Microsoft guy I spoke with at BUILD, it does indeed. There may be some limitations as to what can be vectorized, and he only mentioned SSE, not SSE2 or AVX.

Answer 2
