Michael Leahy spoke on AnDevCon’13 about OpenCL on Android. Enjoy the overview! Subjects (globally): What is OpenCL 13 dwarfs RenderScript Demo Mr.Leahy is quite critical about Google’s recent decisions to try to block OpenCL in favour of their own proprietary RenderScript Compute (now mostly referred to as just “RenderScript” as they failed on pushing twin

The main problem of discrete GPUs is that memory needs to be transferred from CPU-memory to GPU-memory. Luckily we have SoCs (GPU and CPU in one die), but still you need to do in-memory transfers as the two processors cannot access memory outside their own dedicated memory-regions. This is due the general architecture of computers,

On 15 – 17 April 2014 a 3-day workshop around HPC is organised. It is free, and focuses on bringing industry and academy together. Research Institute for Symbolic Computation (RISC) / Johannes Kepler University Linz Kirchenplatz 5b (Castle of Hagenberg) 4232 Hagenberg Austria The PRACE Spring School 2014 will take place on 15 – 17 April

Thursday 13 February 2014 the first Khronos meetup in will take place. We expect a small group, so the location will be cozy and there will be enough time to talk with a beer. First round is on me, admission is free. Goal is to learn about open media-standards from Khronos and others. So when

While CUDA has had the advantage of having many more libraries, this is no longer its main advantage if it comes to linear algebra. If one thing changed over the past year, then it is linalg library-support for OpenCL. The choices have been increased at a continuous rate, as you can see the below list.

If one thing can be said about Europe, is that it is quite diverse. Each country  solves or fails to solve its own problems individually, while European goals are not always well-cared for. Nevertheless, you can notice things changing. One of the areas where things have changed, is that of HPC. HPH  has always been a well-interconnected

Toolmaker VectorFabrics sent 9 predictions for this year in their newsletter. I’d like to share it with you. Nine predictions for 2014 that prove the programming landscape is changing It is not hard to predict that this year will see a lot of activity around multicores and manycores. 2014 will be the year that software

According to the latest newsletter of the Mont-Blanc Project, it was explained that the GPU on a Samsung Exynos 5 is much faster and greener than its CPU: 3.5 times faster with half the energy. They built a supercomputer using 810 Exynos SoCs, that can deliver a 26 TFLOPS of peak performance. With the upcoming

More and more professional media software now has support for OpenCL. It starts to be a race where you cannot stay behind. If the competitor runs more than twice as fast on the same hardware, then you just can’t say “Sorry, you should buy NVIDIA hardware”. I expected this to happen, but could not tell

OpenCL SPIR (Standard Portable Intermediate Representation) is an intermediate representation for OpenCL-code, comparable to LLVM IL and HSAIL. It is a search for what would be a good representation, such that parallel software runs well on all kinds of accelerators. LLVM IL is too general, but SPIR is a subset of it. I’ll discuss HSAIL,
