China’s Tianhe-2 Supercomputer takes top ranking, a win for Intel vs Nvidia

The International Supercomputing Conference (ISC) is under way in Leipzig, and one of the announcements is that China’s Tianhe-2 is now the world’s fastest supercomputer according to the Top 500 list.

This has some personal interest for me, as I visited its predecessor Tianhe-1A in December 2011, on a press briefing organised by NVidia which

Intel fights back against iOS with free tools for HTML5 cross-platform mobile development

Today at its Software Conference in Paris Intel presented its HTML5 development tools.

There are several components, starting with the XDK, a cross-platform development kit based on HTML5, CSS and JavaScript designed to be packaged as mobile apps using Cordova, the open source variant of PhoneGap.

There is an intriguing comment here:

The XDK

Intel Xeon Phi shines vs NVidia GPU accelerators in Ohio State University tests

Which is better for massively parallel computing, a GPU accelerator board from NVidia, or Intel’s new Xeon Phi? On the eve of NVidia’s GPU Technology Conference comes a paper which Intel will enjoy. Erik Sauley, Kamer Kayay, and Umit V. C atalyurek from the Ohio State University have issued a paper with performance comparisons between

Images of Eurora, the world’s greenest supercomputer

Yesterday I was in Bologna for the press launch of Eurora at Cineca, a non-profit consortium of universities and other public bodies. The claim is that Eurora is the world’s greenest supercomputer.

Eurora is a prototype deployment of Aurora Tigon, made by Eurotech. It is a hybrid supercomputer, with 128 CPUs supplemented by 128

Programming NVIDIA GPUs and Intel MIC with directives: OpenACC vs OpenMP

Last month I was at Intel’s software conference learning about Many Integrated Core (MIC), the company’s forthcoming accelerator card for HPC (High Performance Computing). This month I am in San Jose for NVIDIA’s GPU Technology Conference learning about the latest development in NVIDIA’s platform for accelerated massively parallel computing using GPU cards and the CUDA

Windows 8 to be called Windows 8, no Outlook on ARM

Microsoft has announced the range of editions planned for Windows 8, which is now the official name (previously it was a code name).

Here is what I found interesting. Windows on Arm (WOA) is now called Windows RT and ships with Office included. However, Outlook is not included, confirming my suspicion that Outlook may gradually

Multicore processor wars: NVIDIA squares up to Intel

I first became aware of NVIDIA’s propaganda war against Intel at the 2012 GPU Technology conference in Beijing. CEO Jen-Hsun Huang stated that CPUs are remarkably inefficient for multicore processing:

The CPU is fast and is terrific at single-threaded performance, but because so much of the electronics inside the CPU is dedicated to out of

ITWriting.com awards 2011: ten key happenings, from Nokia’s burning platform to HP’s nightmare year

2011 felt like a pivotal year in technology. What was pivoting? Well, users are pivoting away from networks and PCs and towards cloud and devices. The obvious loser is Microsoft, which owns PCs and networks but is a distant follower in devices and has mixed prospects in the cloud. Winners include Apple, Google, Amazon, and

On Supercomputers, China’s Tianhe-1A in particular, and why you should think twice before going to see one

I am just back from Beijing courtesy of Nvidia; I attended the GPU Technology conference and also got to see not one but two supercomputers:  Mole-8.5 in Beijing and Tianhe-1A in Tianjin, a coach ride away.

Mole-8.5 is currently at no. 21 and Tianhe-1A at no. 2 on the top 500 list of the world’s

NVIDIA plans to merge CPU and GPU – eventually

I spoke to Dr Steve Scott, NVIDIA’s CTO for Tesla, at the end of the GPU Technology Conference which has just finished here in Beijing. In the closing session, Scott talked about the future of NVIDIA’s GPU computing chips. NVIDIA releases a new generation of graphics chips every two years:

2008 Tesla 2010 Fermi 2012
