Then it hit the doormat: “AMD is proud to collaborate with ASUS, the Frankfurt Institute for Advanced Studies, (FIAS) and GSI to support such important physics and computer science research,” said David Cummings, senior director and general manager, professional graphics, AMD. “This installation reaffirms AMD’s leading role in HPC with the implementation of the AMD

During SC14 (SuperComputing Conference 2014), OpenCL is again all over New Orleans. Just like last year, I’ve composed an overview based on info from the Khronos website and the SC2014 website. Finally I’m attending SC14 myself, and will give two talks for you. Tuesday I’ll be part of a 90 minute session of Khronos, where
Getting about the same code in C and OpenCL has lots of advantages, when maximum optimisations and vectors are not needed. One thing I bumped into myself was that rounding in C++ is different, and decided to implement the OpenCL-functions for rounding in C. The OpenCL-page for rounding describes many, many functions with this line:

Below is a (slightly edited) repost of a blog by David Bucciarelli (homepage, twitter) on the Luxrender forum. I find micro-kernels an important subject, since micro-kernels have clear advantages. In OpenCL 2.0 there are more possibilities to create smaller kernels. Also making smaller and more focused functions is considered good software engineering, defined as “Separation

GROMACS is an important molecular simulation kit, which can do all kinds of “soft matter” simulations like nanotubes, polymer chemistry, zeolites, adsorption studies, proteins, etc. It is being used by researches worldwide and is one of the bigger bio-informatics softwares around. To speed up the computations, GPUs can be used. The big problem is that

A while ago macresearch.com stopped from existing, as David Gohara pulled the plug. Luckily the sources of a very nice tutorial were not lost, and David gave us permission to share his material. Even if you don’t have a MAC, then these almost 5 year old materials are very helpful to understand the basics (and

We have some embedded devices here, which badly need attention. Some have gotten some private time on the bench, but we did not share anything on the blog yet with our readers. We simply need some extra hands to do this. Because it’s actually cool to do, but admittedly a bit boring when doing several
We’re looking for an intern to do the cool stuff: benchmarking and Linux wizarding Read More »
The research lab LaSEEB (Lisboa, Portugal) is active in the areas of Biomedical Engineering, Computational Intelligence and Evolutionary Systems. They create software using OpenCL and CUDA to speed-up their research and simulations. They were one of the first groups to try out OpenCL, even before StreamHPC existed. To simplify the research at the lab, Nuno

Altera has just released the free ebook FPGAs for dummies. One part of the book is devoted to OpenCL, so we’ll quote some extracts here from one of the chapters. The rest of the book is worth a read, so if you want to check the rest of the text, just fill in the form on Altera’s webpage. In StreamHPC
