Why Intel® Parallel Advisor?

Multi-core processors are ubiquitous now and it has become necessary to exploit the additional processing capabilities afforded by the multiple cores. Software written for single-core processors with serial execution in mind now needs to be retargeted to multi-core processors. We are obviously talking about programs which execute on a single machine and in a single process rather than those that are multi-process or those that execute on a distributed cluster.

3D Vector Normalization Using 256-Bit Intel® Advanced Vector Extensions (Intel® AVX)

This article shows how to use 256-bit Intel® Advanced Vector Extensions (Intel® AVX) to normalize an array of 3D vectors. We describe a shuffle approach to convert between AOS & SOA on-the-fly in order to make data ready for up to 8-wide SIMD processing.

    nulstein v2 - slide 08

    (note: this is slide 8 of the nulstein plog)

    At the heart of nulstein in particular and, really, at the heart of any multicore piece of software, is a mechanism to dispatch work. Before we worry about when or how each piece of work can or can't access data, we need to figure out how to get everything to run, efficiently.
