After two events in the Netherlands, the third GPGPU-day will be held in Copenhagen! Speakers are researchers and companies from the Nordic and Scandinavian countries. If you’re interested in speaking at the conference, get in touch. Date: 29 September 2015 Location:…

Update: C++ has been moved from OpenCL 2.1 to 2.2, being released in 2017. Title and text have been updated to reflect this. A reason why Apple released Metal might be the reason that Khronos was too slow in releasing C++ kernels…

In January 2010 I created the first steps of StreamComputing (redacted: rebranded to StreamHPC in 2017), by registering the website and writing a hello-world article. About 4 months of preparations and paperwork later the freelance-company was registered. Then 5 years later…

From all the news that came out of GDC, I’m most eager to talk about SPIR-V. This intermediate language will make a big difference for the compute-industry. In this article I’d like to explain why. If you need a technical explanation…

Remember the times that the OpenCL compilers where not that good as they’re now? Correct source-code being rejected, typos being accepted, long compile times, crashes during compiling and other irritating bugs. These made the work of an OpenCL developer in “the…

Our business is largely around making software faster. For that we use OpenCL, but do you know what this programming language is? Why can’t this speeding-up be done using other languages like Java, C#, C++ or Python? OpenCL the answer to…

A while ago I found the slide at the right, claiming that AMD did not have any direct GPU-GPU communication. I found at several sources there was, but it seems not to be a well-known feature. The feature is known as…

Here in Amsterdam a lot is going on around HPC. Including StreamHPC, we have companies like Vancis, Netherlands eScience Centre,  and ClusterVision, the research institute for Dutch HPC, Surf SARA, (hosting the Dutch supercomputer) and the very busy Amsterdam IX. Here…

(if you get to Palo Alto, Manchester, Karlsruhe and Copenhagen) We’re supporters of open standards and open discussions. When those thow come together, we melt. Therefore I’d like to share four hot conferences with you: IWOCL (Palo Alto, SF, USA), EMiT…

Getting your Windows machine ready for OpenCL is rather straightforward. In short, you only need the latest drivers for your OpenCL device(s) and you’re ready to go. Of course, you will need to add an OpenCL SDK in case you want…

UPDATE: We now only offer thesis support (“externs”), for students who want to use OpenCL in their research, but don’t have such support at their university. for the rest the below applies. From July there are several internships available here at…

We were too busy lately to tell you about it: OpenCL 2.0 is getting ready for prime time! As it makes use of the more recent hardware features, it’s therefore more powerful than OpenCL 1.x could ever be. To get you…

Years ago I was surprised by the fact that CPUs were also programmable with OpenCL – I solely chose that language for the cool of being able to program GPUs. It was weird at start, but cannot think of a world…

Recent code uses OpenCL 1.2 more and more, which is a problem when wanting to use OpenCL 1.1 devices, or even 1.0 devices. Most times those computers have OpenCL 1.1 libraries installed. So what to do? When you want to make…

The new Hawaii-based GPUs from AMD (Radeon R9 2xx, FirePro W9100 and Firepro S9150) have a lot of improvements, one being a new OverDrive 6 (AMD’s version of NVIDIA GPU Boost). Problem is that it’s not supported yet in the Linux…

The IWOCL 2015 call for OpenCL Papers is now open and is looking for submissions from industry and academia relating to the use of OpenCL.  Submissions may refer to completed projects or those currently in progress and are invited in the form of: Research…
