Parallel Power to the Programmer: Coding Course Leads the Way

As systems with multiple CPUS, each carrying multiple cores become increasingly popular for a large variety of workloads, organizations unsurprisingly want to take full advantage of each CPU and coprocessor that are part of the execution environment. Those who include Xeon Phi coprocessors as part of their infrastructure will be …

How Vectorization Feeds Your Need for Speed

So, you’ve written a program but it’s data-intensive and you need more speed without forking out for a new computer? Maybe you’ve tried alternative algorithms, maxed out concurrency but still need more speed.  Could be it’s time to try vectorization. What is Vectorization? Vectorization is CPU hardware that can speed …

Fine Tune Performance of Auto-Vectorized Loops

Many programmers take advantage of the automatic vectorization features of Xeon Phi coprocessors. However, as this paper by Andrey Vladimirov of Colfax International shows, taking advantage of some common fine-tuning techniques including strength reduction and data alignment can produce dramatic results. See how Colfax was able to improve coprocessor performance …
