It's not often that the internecine rivalries of the HPC research and development community spill over into the public arena. However, a video recently posted on YouTube (and the associated comments), ostensibly a light-hearted advert for a SC15 tutorial on heterogenous programming, shows how real and deep these rivalries can be.

I'm just back from giving my first PRACE training session as part of the joint PRACE/SNIC* Spring School based at Umeå Univeristat in northern Sweden. For those whose Nordic geography is like mine, here's a map...

Programmability of GPUs (or accelerators in general) has improved since the days of the OpenGL shaders. First CUDA, and OpenCL later, have evolved to offer a reasonable way of programming efficient algorithms onto GPUs. However, despite this improvement, there is still a lot of effort involved in the development of code for accelerators. This is inevitable sometimes: if you have a particular algorithm and you want to have the maximum performance possible for a particular accelerator architecture, and you have the time to do it, you can immerse yourself in the marvellous world of CUDA/OpenCL low-level optimisation and stop reading. If time is critical for you, as it is for me, then you will love the latest advance in accelerator programmability: OpenACC.
