With widening vectors and the proliferation of advanced vector instructions in today's processors, vectorization plays an ever-increasing role in delivering application performance. Achieving the performance potential of this vector hardware has required significant support from the software level such as new explicit vector programming models and advanced vectorizing compilers. Today, with the combination of these software tools plus new SIMD ISA extensions like gather/scatter instructions it is not uncommon to find that even codes with complex and irregular data access patterns can be vectorized.
