You can’t ignore accelerators when designing a new cluster for HPC anymore. Back in 2010 I suggested to use GPUs to enter the Top 500 with a budget of only €38k. It takes ten times more now, as almost everybody started to use accelerators. To get into the November top 500 would roughly take a

At Intel they have CPUs (Xeon, Ivy Bridge), GPUs (Isis) and Accelerators (Xeon Phi). OpenCL enables each processor to be used to the fullest and they now promote it as such. Watch the below video and see their view on why OpenCL makes a difference for Intel’s customers. This is important, because till recently Intel

Khronos just announced three OpenCL based releases:  SYCL 1.2 Provisional Spec – Abstraction Layer for Leveraging C++ and OpenCL WebCL 1.0 Final Spec – JavaScript bindings to OpenCL OpenCL 2.0 Adopters Program – Conformance for OpenCL 2.0 implementations Below I’ve quoted the summaries. For each of these I’ve prepared articles, but due to lack of

Khronos just sent out the below message to Press and Game Developers. To my understanding, there are many game devs under the readers of this blog, so I’d like you to share the message with you. JOIN KHRONOS GROUP AT GDC 2014 SAN FRANCISCO Press Conference, Technology Sessions and Refreshment OasisWe invite you to attend

This article actually discusses the question: is GPGPU a solution for the masses, or is it for niche-products? For the latter open standards matter a lot less, as you will read. If you watch the below video on sale&marketing by Victor Antonio, then you get what is so difficult about open standards: It pushes all

Wanting to test your OpenCL-software on specific hardware? From now on, that is possible by logging in on StreamHPCs test-servers. Update: new prices. Got feedback it should compete with Amazon EC2. During the beta-period (February to April) we have available: [list1] Dual FirePro S10000 (total ~11.8 TFLOPS single precision, ~2.9 TFLOPS double precision). Several embedded

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
