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 high-level languages, where we were promised superfast software that was very quick to write.

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 SDI (mostly on network-cards, SSDs and FPGAs), but not much information is found on

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 in Amsterdam we’re focused on building up more local companies around big compute and

(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 (Manchester, UK), ParallelCon (Karlsruhe, Germany), GPGPU-day 2015 (Copenhagen, Denmark). On all these conferences I’ll

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 to develop OpenCL applications but that’s equally easy. Before we start, a few notes:

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 StreamHPC, all around self-driving vehicles (or even self-flying drones). This means that with an

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 up to speed, see this list of new OpenCL 2.0 features: Shared Virtual Memory:

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 without OpenCL working on a CPU. But why is it important? Who cares about

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 code that runs on both on Nvidia, AMD and Intel, then you have two

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 drivers and you will get too low performance – it probably will be solved
