Context Matters: Distributed Graph Algorithms and Runtime Systems

In this video from the PASC16 conference, Andrew Lumsdaine from Indiana University presents: Context Matters: Distributed Graph Algorithms and Runtime Systems. “The increasing complexity of the software/hardware stack of modern supercomputers makes understanding the performance of the modern massive-scale codes difficult. Distributed graph algorithms (DGAs) are at the forefront of that complexity, pushing the envelope with their massive irregularity and data dependency. We analyze the existing body of research on DGAs to assess how technical contributions are linked to experimental performance results in the field. We distinguish algorithm-level contributions related to graph problems from “runtime-level” concerns related to communication, scheduling, and other low-level features necessary to make distributed algorithms work. We show that the runtime is an integral part of DGAs’ experimental results, but it is often ignored by the authors in favor of algorithm-level contributions.”

Video: Rolling Out the New Intel Xeon Phi Processor at ISC 2016

In this video from ISC 2016, Barry Davis from Intel describes the company’s brand new Intel Xeon Phi Processor and how it fits into the Intel Scalable System Framework. “Eliminate node bottlenecks, simplify your code modernization and build on a power-efficient architecture with the Intel Xeon Phi™ processor, a foundational element of Intel Scalable System Framework. The bootable host processor offers an integrated architecture for powerful, highly parallel performance that will pave your path to deeper insight, innovation and impact for today’s most-demanding High Performance Computing applications, including Machine Learning. Supported by a comprehensive technology roadmap and robust ecosystem, the Intel Xeon Phi processor is a future-ready solution that maximizes your return on investment by using open standards code that are flexible, portable and reusable.”

Video: Announcing Intel HPC Orchestrator

In this video from ISC 2016, Figen Ulgen from Intel describes the new Intel HPC Orchestrator. “Intel HPC Orchestrator simplifies the installation, management and ongoing maintenance of a high-performance computing system by reducing the amount of integration and validation effort required for the HPC system software stack. Intel HPC Orchestrator can help accelerate your time to results and value in your HPC initiatives. With Intel HPC Orchestrator, based on the OpenHPC system software stack, you can take advantage of the innovation driven by the open source community – while also getting peace of mind from Intel support across the stack.”

Interview: Dr. Eng Lim Goh on the Latest Trends in High Performance Data Analytics

In this video from ISC 2016, Dr. Eng Lim Goh from SGI discusses the latest trends in high performance data analytics and machine learning. “Dr. Eng Lim Goh joined SGI in 1989, becoming a chief engineer in 1998 and then chief technology officer in 2000. He oversees technical computing programs with the goal to develop the next generation computer architecture for the new many-core era. His current research interest is in the progression from data intensive computing to analytics, machine learning, artificial specific to general intelligence and autonomous systems. Since joining SGI, he has continued his studies in human perception for user interfaces and virtual and augmented reality.”

93 Petaflop Chinese Supercomputer is World’s Fastest on Latest TOP500 List

A new machine called Sunway TaihuLight in China is the fastest supercomputer on the planet. Announced today with the release of the latest TOP500 list, the 93 Petaflop machine sports over 10.6 Million compute cores. “The latest list marks the first time since the inception of the TOP500 that the U.S is not home to the largest number of systems. With a surge in industrial and research installations registered over the last few years, China leads with 167 systems and the U.S. is second with 165. China also leads the performance category, thanks to the No. 1 and No. 2 systems.”

Asetek to Premier VerticalRackCDU Liquid Cooling at ISC 2016

Today Asetek announced plans to showcase its liquid cooling solutions and successful installations at ISC 2016 in Frankfurt. “For the first time, Asetek will be displaying its new InRackCDU cooling solution. InRackCDU provides the option of having RackCDU mounted in the server rack. InRackCDU does not take up aisle space and includes the same monitoring features as Asetek’s VerticalRackCDU.”

Challenges for Climate and Weather Prediction in the Era of Heterogeneous Architectures

Beth Wingate from the University of Exeter presented this talk at the PASC16 conference in Switzerland. “For weather or climate models to achieve exascale performance on next-generation heterogeneous computer architectures they will be required to exploit on the order of million- or billion-way parallelism. This degree of parallelism far exceeds anything possible in today’s models even though they are highly optimized. In this talk I will discuss the mathematical issue that leads to the limitations in space- and time-parallelism for climate and weather prediction models – oscillatory stiffness in the PDE.”

Industry Vets Combine Forces to Launch HPC Marketing Powerhouse

Today insideHPC is pleased to share news about Xand McMahon a newly formed marketing agency focused on HPC and technical computing. “Xand McMahon is a joint venture between two familiar faces in the HPC community: Lara Kisielewska from Xand Marketing and Kim McMahon from McMahon Consulting. As kind of a one-stop shop, Xand McMahon provides a full range of strategic and tactical marketing services for companies seeking to capture market share in HPC and technical computing. Both women entered the HPC arena in 1999 and have worked with dozens of HPC firms to provide messaging and branding, go-to-market strategies, advertising, PR, social media, event production, road shows, trade show management, technical content, partner management, lead generation, and product launches.”

EXTOLL Network Chip Enables Network-attached Accelerators

Today EXTOLL in Germany released its new TOURMALET high-performance network chip for HPC. “The key demands of HPC are high bandwidth, low latency, and high message rates. The TOURMALET PCI-Express gen3 x16 board shows an MPI latency of 850ns and a message rate of 75M messages per second. The message rate value is CPU-limited, while TOURMALET is designed for well above 100M msg/s.”

E4 to Showcase GPU-Accelerated OpenPOWER Servers at ISC 2016

Today Italy’s E4 Computer Engineering announced plans to showcase of new NVIDIA GPU-accelerated OpenPOWER servers at ISC 2016 in Frankfurt. “For this edition of ISC16, we wanted to reinforce the message that E4 is a company that actively engages and pursues new technologies’ paths with the aim to deliver leading-edge solutions for a number of demanding environments,” said Piero Altoè, Marketing and BDM Manager, E4 Computer Engineering. “Our priority is to collaborate with organizations such as OpenPOWER Foundation and true visionaries like NVIDIA in order to obtain powerful, scalable and affordable solutions for a number of complex applications and contribute to the development of technologies that have a huge impact on many aspects of our lives.”
