Intel® Developer Zone:
Intel® AVX

Vision Statement

The need for greater computing performance continues to grow across industry segments. To support rising demand and evolving usage models, we continue our history of innovation with the Intel® Advanced Vector Extensions (Intel® AVX).

Intel® AVX is a new-256 bit instruction set extension to Intel® SSE and is designed for applications that are Floating Point (FP) intensive. It was released early 2011 as part of the Intel® microarchitecture code name Sandy Bridge processor family and is present in platforms ranging from notebooks to servers. Intel AVX improves performance due to wider vectors, new extensible syntax, and rich functionality. This results in better management of data and general purpose applications like image, audio/video processing, scientific simulations, financial analytics and 3D modeling and analysis.

Optimize for Intel® AVX Using Intel® Math Kernel Library's Basic Linear Algebra Subprograms (BLAS) with DGEMM Routine
By Gregory Henry (...4spacer
Introduction Although our initial efforts supports tunings and functionality in three areas, the Intel® Math Kernel Library (Intel® MKL), provides a broader set of functionality for scientific and engineering use. These are highlighted below: Linear Algebra – Basic Linear Algebra Subprograms (BLAS . . .

Is AVX enabled?
By victoria-zhisli...Posted April 14th 20114spacer
If we ask anyone who  uses or plans to use or just advertises the intrinsic compiler functions for SIMD support (MMX, SSE, AVX):  why do you do so, why it is good? The answer definitely will be something like this:"Intrinsics provide a C/C++ language interface to assembly instructions, so that we ...
