SIMD: Key to Understanding Vectorization

In the blog How Vectorization Feeds Your Need for Speed, I described vectorization–a technique that uses SIMD (Single Instruction Multiple Data) instructions provided in SSE and AVX extensions to do data operations in parallel in 128 or 256 bit registers. Now, let’s look at what those SIMD instructions are. Although …
