OpenCL at SC14

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 […]

OpenCL integer rounding in C

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: […]

Mega-kernel versus Micro-kernels in LuxRender (repost)

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 […]

We ported GROMACS from CUDA to OpenCL

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 […]

OpenCL tutorial videos from Mac Research

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 […]
