China’s HPC Vendors Look to US and European Markets

Who are the world’s most important vendors of supercomputers, at least as measured by the number of systems they have in the Top500? HP is the leader with a 31 per cent share; Cray is number two with just under 14 per cent. So far, so unsurprising. But what has been little remarked upon is that in third place – with 49 systems, or 9.8 per cent of the Top500 list – is the Chinese vendor, Sugon. And both Sugon and Inspur, the other main Chinese vendor, have their sights set on expanding still further, with trade missions to Europe and setting up partnerships and subsidiaries in both Europe and the USA.

Video: GPUltima – The Ultimate in GPU Networks

Steve Cooper from One Stop Systems presented this talk at SC15. “The OSS GPUltima is the densest and most cost-effective petaflop solution for scalable data center infrastructures,” said Steve Cooper, OSS CEO. “Supporting up to 128 NVIDIA Tesla K80 GPU accelerators, the OSS GPUltima shows tremendous performance gains in many applications like oil and gas exploration, financial calculations, and medical devices. Providing ample cooling and power to accommodate this many high-end cards, it surpasses other devices in performance. In addition, the OSS GPUltima is a preconfigured rack of GPUs, servers and interconnections already integrated and the whole unit is tested and ready to add application software.”

Piz Kesch: The Making of a GPU-based Weather Forecasting System

Thomas Schulthess from CSCS presented this talk at the Nvidia booth at SC15. “On October 1, 2015 “Piz Kesch”, a Cray CS-Storm system with NVIDIA K80 GPUs became operational at CSCS on behalf of MeteoSwiss. In this talk, we will discuss the hardware-software co-design project behind this most cost and energy efficient system for numerical weather prediction.”

Is HPC Heading Towards Openness, Chaos, or a Split?

“To be successful in high-performance computing (HPC) today, it is no longer enough to sell good hardware: vendors need to develop an ‘ecosystem’ in which other hardware companies use their products and components; in which system administrators are familiar with their processors and architectures; and in which developers are trained and eager to write code both for the efficient use of the system and for end-user applications. No one company, not even Intel or IBM, can achieve all of this by itself anymore.”

JYU Sets World Record for Pore-scale Flow Simulations

An interdisciplinary research team from JYU in Finland has set a new world record in the field of fluid flow simulations through porous materials. The team, coordinated by Dr. Keijo Mattila from the University of Jyväskylä, used the world’s largest 3D images of a porous material–synthetic X-ray tomography images of the microstructure of Fontainebleau sandstone, and successfully simulated fluid flow through a sample of the size of 1.5 cubic centimeters with a submicron resolution.

Video: Blazegraph Accelerates Graph Computing with GPUs

“Analytics applied over complex, many-to-many data relationships hit the ‘Graph Cache Thrash’ bottleneck and grind to a halt, failing to deliver good performance or to operate at scale,” said Brad Bebee, SYSTAP CEO. “GPU hardware provides a compelling performance increase for data-intensive, predictive analytic applications. With Blazegraph and our new GPU products, users can harness the computing power comparable to what was only available from supercomputers, such as a Cray, at a fraction of the cost.”

Irish Supercomputer List Reflects HPC Growth

The fifth Irish Supercomputer List was released today with a full ranking of the nation’s HPC systems. Launched in November 2013 to raise the profile of High Performance Computing in Ireland and abroad, the list is updated twice annually with a continuous open call for participation from users and maintainers of Irish HPC installations.

Is the Future CPU+GPU or CPU+FPGA?

“At SC15, IBM, in turn, announced new offerings centered “on the tight integration of IBM’s Power processors with accelerators.” But it was an announcement about IBM’s interest in FPGAs that attracted attention. It has concluded a multi-year strategic collaboration with Xilinx to develop FPGA-enabled workload acceleration on Power-based systems. Through a private commercial agreement as well as by collaboration through the Open Power Foundation, the two companies are teaming up to develop open acceleration infrastructures, software, and middleware.

2016 Hackathons Seeking Team Applications

“The goal of each hackathon is for current or prospective user groups of large hybrid CPU-GPU systems to send teams of at least 3 developers along with either (1) a (potentially) scalable application that needs to be ported to GPU accelerators, or (2) an application running on accelerators which needs optimization. There will be intensive mentoring during this 5-day hands-on workshop, with the goal that the teams leave with applications running on GPUs, or at least with a clear roadmap of how to get there. Our mentors come from national laboratories, universities and vendors, and besides having extensive experience in programming with OpenACC/CUDA, many of them develop the GPU-capable compilers and help define the OpenACC standard.”

Accelerated Computing: The Path Forward

Nvidia’s Jen-Hsun Huang and Ian Buck presented this talk at SC15. “Supercomputing has swept rapidly from the far edges of science to the heart of our everyday lives. And propelling it forward – bringing it into the mobile phone already in your pocket and the car in your driveway – is GPU acceleration, Nvidia CEO Jen-Hsun Huang told a packed house at a rollicking event kicking off this week’s SC15 annual supercomputing show in Austin. The event draws 10,000 researchers, national lab directors and others from around the world.”
