Just to let you know that there should be even more OpenCL and related technologies on SC14 Are you interested in hosting a workshop at SC14? Please mark your calendars as SC will be accepting proposals from 1 January – 7 February for independently planned full-, half-, or multi-day workshops. Workshops complement the overall SC

Last week I needed to get Fortran working with OpenCL. As the example-page is not up-to-date and not much documentation is on the interwebs outside the official page, this was not as straight-forward as I hoped. The test-suite and this article provided code I could actually use. First I wanted to have things in a

Khronos has supported and organised for the second time the International Workgroup on OpenCL (IWOCL, pronounced as “eye-wok-ul”). Last year the event took place at Georgia Tech, Atlanta, Georgia, in the United States. This year the event will be held in Europe: Bristol University, Bristol, England, UK. IWOCL 2013 Presentations Last year there was a

When the new supercomputer “Cartesius” of the Netherlands was presented to the public a few months ago, the buzz was not around FLOPS, but around users. SARA CEO Dr. Ir. Anwar Osseyran kept focusing on this aspect. The design of the machine was not pushed by getting into the TOP500, but by improving the performance

During the last training I got a question how to do malloc in the kernel. It was one of those good questions, as it gives another view on a basic concept of OpenCL. Simply put: you cannot allocate (local or global) memory from within the kernel. Luckily it’s possible, but it is somewhat hidden in

For those working in a research-department at a company or university within the EU, Horizon 2020 might be a bit of a familiar sound. For us this is an important program and a source possibilities for collaboration in the coming years. Our expertise in enabling ultra-fast computations, combined with your expertise can make Europe more competitive. We

Every second Monday of the month StreamHPC offers an OpenCL training in Mathematics or Media-operations. The target is OpenCL 1.2 (or 1.1 when NVIDIA is discussed). OpenCL 2.0 trainings will start in Q2/Q3, or when on request. All trainings will be given by experienced OpenCL developers/trainers. Trainings Trainings take 3½ days, from basics on the

Unluckily I am not at SC13, so I’ll enjoy from a distance. Luckily I don’t miss one of the most beautiful 15km runs in the Netherlands. When there is more news, I’ll add to this post – below is mostly taken from the Khronos website and the SC2013 website. OpenCL Booth Meet members of the

Let the competition on large memory GPUs begin! Some algorithms and continuous batch processes will have the joy of the extra memory. For example when inverting a large matrix or doing huge simulations, you need as much memory as possible. or to avoid memory-bank conflicts by duplicating data-objects (possible only when the data is in
