Supercomputing Neutron Star Structures and Mergers

Over at XSEDE, Kimberly Mann Bruch & Jan Zverina from the San Diego Supercomputer Center write that researchers are using supercomputers to create detailed simulations of neutron star structures and mergers to better understand gravitational waves, which were detected for the first time in 2015. “XSEDE resources significantly accelerated our scientific output,” noted Paschalidis, whose group has been using XSEDE for well over a decade, when they were students or post-doctoral researchers. “If I were to put a number on it, I would say that using XSEDE accelerated our research by a factor of three or more, compared to using local resources alone.”

Atos steps up with NVMeOF Flash Accelerator Solutions

Atos recently announced two new flash accelerators for HPC) workloads as part of Atos Smart Data Management Suite. These two new solutions – Smart Burst Buffer (SBB) and Smart Bunch of Flash (SBF) – increase the performance and productivity of HPC I/O intensive applications. They are the most flexible and cost-effective flash accelerators on the […]

ASTRA: A Large Scale ARM64 HPC Deployment

Michael Aguilar from Sandia National Laboratories gave this talk at the Stanford HPC Conference. “This talk will discuss the Sandia National Laboratories Astra HPC system as mechanism for developing and evaluating large-scale deployments of alternative and advanced computational architectures. As part of the Vanguard program, the new Arm-based system will be used by the National Nuclear Security Administration (NNSA) to run advanced modeling and simulation workloads for addressing areas such as national security, energy and science.”

UberCloud Recognized with three HPC Industry Awards

Today the UberCloud announced that it has been recognized in three leading HPC industry awards for two of its innovative engineering projects in the cloud. “We are proud and humbled for the two prestigious Hyperion Innovation Excellence Awards and the HPCwire Editors’ Choice Award,” said Wolfgang Gentzsch, President of UberCloud, “Our innovative projects on UberCloud’s Cloud Simulation Platform showcase engineers, how they can benefit from the cloud to accelerate their simulations and innovate.”

Improving HPC Performance with the Roofline Model

“When we are optimizing our objective is to determine which hardware resource the code is exhausting (there must be one, otherwise it would run faster!), and then see how to modify the code to reduce its need for that resource. It is therefore essential to understand the maximum theoretical performance of that aspect of the machine, since if we are already achieving the peak performance we should give up, or choose a different algorithm.”

Video: Atos Olympe Supercomputer Powers Research at CALMIP

Today Atos announced the deployment of a BullSequana X1000 supercomputer at CALMIP, one of the biggest multi-scale inter-university supercomputing centers in France. Called Olympe, the supercomputer will be used for over 200 research projects in materials, fluid mechanics, universe sciences and chemistry. “The supercomputer has a peak performance of 1,3 petaflop/s bringing 5 times more computing and processing power than that of the previous supercomputer, for the same energy consumption.”

Advancement in AI & Machine Learning Calls For New HPC Solutions

High performance computing has gone through numerous shifts in the past few years. The new HPC, inclusive of analytics and AI, and with its wide range of technology components and choices, presents significant challenges to a commercial enterprise. A new report from Lenovo explores the intersection of HPC and AI, as well tips on how to choose the right HPC provider for your enterprise. 

Video: In-Memory Computing Using Photonic Memory Devices

In this video, IBM researchers describe an all-optical approach to developing direct in-memory multiplication on an integrated photonic device based on non-volatile multilevel phase-change memories. Using integrated photonic technology will potentially offer attractive solutions for using light to carry out computational tasks on a chip in future.

Ai allows for identification of new cancer genes

Researchers at the Barcelona Supercomputing Centre have created a new artificial intelligence-based computational method that accelerates the identification of new genes related to cancer. Prof. Pržulj highlights that this new method to analyze cells “enables the identification of perturbed genes in cancer that do not appear as perturbed in any data type alone. This discovery emphasizes the importance of integrative approaches to analyze biological data and paves the way towards comparative integrative analyzes of all cells.”
