Update September ’13: AMD gets their new GPUs “Volcanic Islands” with GCN 2.0 out in October. For this reason the HD 7970’s price has dropped to €250. This shakes up some of the things described in this article. Update June ’14: It has become clear that Titan is not a consumer device and should be

Better now than never. It has almost been a year, but finally they’re online: the sheets of the GPGPU-day Amsterdam 2012. You can find the sheets at http://www.platformparallel.com/nl/gpgpu-day-2012/abstracts/ – don’t hotlink the files, but link to this page. The abstracts should introduce the sheets, but if you need more info just ask them in the

See the widget at the right showing if your browser+computer supports WebCL? It is available under the GPL 2.0 license and based on code from WebCL@NokiaResearch (thanks guys for your great Firefox-plugin!) Download from WordPress.org and unzip in /wp-content/plugins/. Or (better), search for a new plugin: “WebCL”. Feedback can be given in the comments. I’d

Which algorithms map is best to which accelerator? In other words: What kind of algorithms are faster when using accelerators and OpenCL/CUDA? Professor Wu Feng and his group from VirginiaTech took a close look at which types of algorithms were a good fit for vector-processors. This resulted in a document: “The 13 (computational) dwarves of

December 2013: Videos are not ready yet, but link will be put here. Amsterdam, 20 June – Applied GPGPU-days in Amsterdam. Keep your agenda free for this event. What can you do with GPUs to speed up computations? This year we can see various examples where OpenCL and CUDA have been used. We hope to

Bored at work? Go start working for one of the anti-boring GPU-expert companies: StreamHPC (Netherlands, EU), Appilo (Israel) or AccelerEyes (Georgia, US). We all look for people who know how to code GPUs. Experience is key, so you need to have at least one year of experience in GPU-programming. Submit your CV now and don’t

The Tokyo Demo Fest 2013 is one of the many demo-parties around the globe. At such parties is where great programmers meet great artists and show off what came out of their collaborations. The winner of this year used OpenCL to compute real-time procedurally generated geometries. For the rest C++, OpenGL and Gamemonkey Script was

GPUVerify is a tool for formal analysis of GPU kernels written in OpenCL and CUDA. The tool can prove that kernels are free from certain types of defect, such as data races and bugs. This is quite useful feedback for any GPU-programmer. Below you find a online version of the tool (please don’t break it!).

Knowing all errors by heart is good for quick programming, but not always the best option. Therefore I started to create a full list with extra info, taken from cl.h and the reference documentation. The problem with many error-codes is that they are sometimes context-dependent and then become quite useless in helping the programmer out.

StreamHPC supports the ERSA conference, 22-25 July in Las Vegas. At that conference there will be an award given to “Best Young Entrepreneur” and I’d like you to send in a proposal. The winner gets an NVIDIA Tesla K20! Young entrepreneurs and academics with a great product/project are invited to present their solution. As the
