Machine Learning with Parallel Studio

Parallel Studio can make many difficult tasks much easier, and have them perform better. Specifically, the Math Kernel Library is used to perform regression testing on data sets using five lines of code. As an alternate, regression testing using OpenMP is shown as an additional way to use Parallel Studio …

Fast Matrix Multiply Fortran Program Using OpenMP

David Bolton demonstrates how to speed up an intensive Fortran program, making it three times as fast by using OpenMP. First, he runs an unoptimized version that takes about 18 seconds to do a matrix multiplication of two 650 x 650 arrays. Then he runs it optimized in just six …

Speed Up Image Processing with OpenMP

Image processing can be significantly optimized with the help of OpenMP. Rick Leinecker shows you how, walks you through the OpenMP techniques employed that make the processing faster, and analyzes an iterative OpenMP construct. Since OpenMP applies concurrent processor operations, synchronization is essential to avoid race conditions. In the demonstration …

Tapping into Random Number Generators in MKL

The Math Kernel Library (MKL) includes a whole set of random number generators that are parallel-friendly and thread-safe. These generators can quickly fill entire arrays with random numbers, even when the arrays contain millions of elements, all with a single function call. Jeff Cogswell puts them to use and looks …
