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 …continue reading China’s Tianhe-2 Supercomputer takes top ranking, a win for Intel vs Nvidia NVIDIA CEO Jen-Hsun Huang has announced the Grid Visual Computing Appliance (VCA). Install one of these, and users anywhere on the network can run graphically-demanding applications on their Mac, PC or tablet. The Grid VCA is based on remote graphics technology announced at last year’s GPU Technology Conference. This year’s event is currently under way …continue reading NVIDIA’s Visual Computing Appliance: high-end virtual graphics power on tap NVIDIA CEO Jen-Hsun Huang made a number of announcements at the GPU Technology Conference (GTC) keynote yesterday, including an updated roadmap for both desktop and mobile GPUs. Although the focus of the GTC is on high-performance computing using Tesla GPU accelerator boards, Huang’s announcements were not limited to that area but also covered the …continue reading Big GPU news at NVIDIA tech conference including first Tegra with CUDA 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 …continue reading Intel Xeon Phi shines vs NVidia GPU accelerators in Ohio State University tests 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 …continue reading Images of Eurora, the world’s greenest supercomputer Nvidia’s Bill Dally has posted about the company’s progress towards exascale computing, boosted by a $12.4 million grant from the U.S. Department of Energy. He mentions that it would be possible to build an exascale supercomputer today, if you could supply enough power: Exascale systems will perform a quintillion floating point calculations per second (that’s …continue reading Exascale computing: you could do it today if you could supply the power says Nvidia 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 …continue reading Programming NVIDIA GPUs and Intel MIC with directives: OpenACC vs OpenMP Yesterday NVIDIA announced the Geforce GRID, a cloud GPU service, here at the GPU Technology Conference in San Jose. The Geforce GRID is server-side software that takes advantage of new features in the “Kepler” wave of NVIDIA GPUs, such as GPU virtualising, which enables the GPU to support multiple sessions, and an on-board encoder …continue reading The pros and cons of NVIDIA’s cloud GPU NVIDIA’s GPU Technology conference is an unusual event, in part a get-together for academic researchers using HPC, in part a marketing pitch for the company. The focus of the event is on GPU computing, in other words using the GPU for purposes other than driving a display, such as processing simulations to model climate change …continue reading NVIDIA’s GPU in the cloud: will you still want an Xbox or PlayStation? NVIDIA has ported its Nsight development tools, previously a plug-in for Visual Studio, to run within the open source Eclipse IDE for use on Mac and Linux. The Nsight tools include profiling, refactoring, syntax highlighting and auto-completion, as well as a bunch of code samples. The Windows version for Visual Studio has also been …continue reading NVIDIA Nsight comes to Eclipse for Mac, Linux GPU programming |
