Massive-Scale Analytics Applied to Real-World Problems

David Bader from Georgia Tech gave this talk at PASC18. “Emerging real-world graph problems include: detecting and preventing disease in human populations; revealing community structure in large social networks; and improving the resilience of the electric power grid. Unlike traditional applications in computational science and engineering, solving these social problems at scale often raises new challenges because of the sparsity and lack of locality in the data, the need for research on scalable algorithms and development of frameworks for solving these real-world problems on high performance computers, and for improved models that capture the noise and bias inherent in the torrential data streams.”

Porting HPC Codes with Directives and OpenACC

In this video from ISC 2018, Michael Wolfe from describes how scientists can port their code to accelerated computing. “OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers interested in porting their codes to a wide-variety of heterogeneous HPC hardware platforms and architectures with significantly less programming effort than required with a low-level model.”

Why the World is Starting to look like a Giant HPC Cluster

“AI, machine learning, is not a (traditional) HPC workload. However, it takes an HPC machine to do it. If you look at HPC, generally, you take a model or things like that, you turn it into an extraordinarily large amount of data, and then you go find some information for that data. Machine learning, on the other hand, takes an extraordinarily large amount of information and collapses it into an idea or a model.”

InfiniBand Powers World’s Fastest Supercomputer

Today the InfiniBand Trade Association (IBTA) announced that the latest TOP500 List results that report the world’s new fastest supercomputer, Oak Ridge National Laboratory’s Summit system, is accelerated by InfiniBand EDR. InfiniBand now powers the top three and four of the top five systems. The latest rankings underscore InfiniBand’s continued position as the interconnect of choice for the industry’s most demanding high performance computing (HPC) platforms. “As the makeup of the world’s fastest supercomputers evolve to include more non-HPC systems such as cloud and hyperscale, the IBTA remains confident in the InfiniBand Architecture’s flexibility to support the increasing variety of demanding deployments,” said Bill Lee, IBTA Marketing Working Group Co-Chair. “As evident in the latest TOP500 List, the reinforced position of InfiniBand among the most powerful HPC systems and growing prominence of RoCE-capable non-HPC platforms demonstrate the technology’s unparalleled performance capabilities across a diverse set of applications.”

Report: Exascale Software Development Project on Track

Software development for future DOE Exascale machines is on track, according to a new Report. While the first Exascale machine is not slated for delivery to Argonne until 2021, ongoing efforts continue towards the monumental task of preparing applications to run 50x faster than possible today. “Software Technology is a key focus area of the ECP and represents the key bridge between Exascale systems and the scientists developing applications that will run on those platforms.”

Penguin Computing to Deploy Supercomputer at ICHEC in Ireland

Today Penguin Computing (a subsidiary of SMART Global Holdings) announced that it will deliver the new national supercomputer to the Irish Centre for High-End Computing (ICHEC) at the National University of Ireland (NUI) Galway. “With 11 supercomputers in the Top500 list and a bare-metal HPC Cloud service since 2009, we knew we could rely on Penguin Computing’s HPC expertise to address our needs in an innovative way.”

NEC Accelerates HPC with Vector Computing at ISC 2018

In this video from ISC 2018, Oliver Tennert from NEC Deutschland GmbH introduces the company’s vector computing technologies for HPC and Machine Learning. “The NEC SX-Aurora TSUBASA is the newest in the line of NEC SX Vector Processors with the worlds highest memory bandwidth. The Processor that is implemented in a PCI-e form factor can be configured in many flexible configurations together with a standard x86 cluster.”

Call for Lustre Presentations: LAD’18 in Paris

The Lustre Administrators & Developers group has issued their Call for Presentations. Registration is now open for the LAD’18 event, which takes place Sept. 24-25 in Paris. “We invite community members to send proposals for presentation. Those talks could cover, by example, tools, administration experiences, configuration setup, developments, tunings, tweaking, … No proceeding is required, just an abstract for a 30-min technical presentation.”

Supermicro Steps up to HPC & AI Workloads at ISC 2018

In this video from ISC 2018, Perry Hayes and Martin Galle from Supermicro describe the company’s latest innovations for HPC and AI workloads. “Supermicro delivers the industry’s fastest, most powerful selection of HPC solutions offering even higher density compute clusters to deliver maximum parallel computing performance for any science and engineering, simulation, modeling, or analytics applications,” said Charles Liang, president and CEO of Supermicro.
