Auto-Vectorization on Channel9

Jim Radigan and I recorded a session for Channel9 last week, as part of the “Going Native” series.  We describe the “auto-vectorizer” – a neat feature in the VS11 compiler backend that analyses loops, in regular, unmodified C++ code, and generates corresponding vector (SIMD) instructions: tight loops using float or int can run up to 4x faster.  The video has just “gone live” at:
