Month: November 2014

With SC14 behind us, there are a few things I’d like to share with you. I’d like to start with the biggest win for OpenCL: AMD leading in the most power-efficient GPU-cluster. A few months ago I wrote a theoretical article…

The OpenCL standard is from the not-for-profit industry consortium Khronos Group. But they do a lot more, like the famous standard OpenGL for graphics. Focus of the group has always been on multimedia and getting the fastest results out of the…

Now that GROMACS has been ported to OpenCL, we would like you to help us to make it better. Why? It is very important we get more projects ported to OpenCL, to get more critical mass. If we only used our…

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….

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…

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…

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…

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….
