In the below list are the members of the OpenCL workgroup as of November 2013. We can expect small changes each year, but this is close to the actual state. I need the rest of Q4 to finalise all the info – any help is appreciated. This list has also been compiled in 2010, and

Something that creates extra value for Open CL is the flexibility with which it runs on an important variety of hardware. A famous strategy is running the code on CPUs to find data-races and debug the code more easily. Another is to develop on GPUs and port to FPGAs to reduce the development-cycles. But there’s

The past year you might not have heard much from OpenCL-on-ARM, besides the Arndale developer-board. You have heard just a small portion of what has been going on. Yesterday the (Linux) OpenCL-drivers for the Chromebook (which contains an ARM MALI T604) the have been released and several companies will launch products using OpenCL. Below are

Support for double precision floating-point type double in OpenCL kernels requires an extension. AMD provides cl_khr_fp64 for newer high-edn hardware, but also a non-fully compliant cl_amd_fp64 extension for other hardware. NVIDIA and Intel support the cl_khr_fp64, so no exceptions need to be made for those drivers. The code you see bellow these lines is based

In the series “Basic Concepts” various basics of GPGPU and OpenCL are discussed. This time we go into a typical one: when an error does not imply the actual problem. It is therefore good to have an overview of all errors with their descriptions. When you get an out-of-resources error or when you get a

There is an interesting book coming up: “Numerical Computations with GPUs” – a book explaining various numerical algorithms with code in CUDA or OpenCL. edit: At the moment there are 21 articles to be included in the book. edit 2: book should be out in July edit 3: Order via Springer International or Amazon US.

For your convenience: an overview of all ARM-GPUs and their driver-availability. Please let me know if something is missing. I’ve added a rating, to friendly push the vendors to get to at least an 7. Vendors can contact me, if they think the rating does not reflect reality. ZiiLabs SDK-page@StreamHPC Drivers can be delivered by

Update: we are very sorry to tell that due to a deadline in a project we were forced to cancel Vincent’s talk. StreamHPC will be at Mosaic3DX in Cambridge, UK, on 30+31 October. The brand new conference managed to get big names on-board, I’m happy to be amongst. Mosaic3DX describes itself as: an international event

This post is part of the series Programming Theories, in which we discuss new and old ways of programming. When discussing the design of programming languages or the extension of existing ones, the question What concepts can simplify the tasks of the programmer? always triggers lots of interesting debates. After that, when an effective solution is
