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

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 Papers Technical Presentations Workshops and Tutorials Posters Examples of sessions from 2014 can be

HiPEAC is an academic oriented, 3-day, international conference around HPC, compilers and processors. Last year was in Vienna, this year in Amsterdam – where StreamHPC also is based. That was an extra reason to go for silver sponsorship, besides I find this conference very important. Compilers have the job to do magic. Last year I

The past ten years we have been happy when we got back home from the office. Our home-computer is simply faster, has more software, more memory and does not take over 10 minutes to boot. Office-computers can be that slow, because 90% of the work is typing documents anyway. Meanwhile the office-servers are mostly used for

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 on how to build the cheapest and greenest supercomputer to enter the Top500 and

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 hardware. Now open source and open standards are getting more important, collabroations like 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 spare resources, we can port one project per year. So the deal is, that
