3 Reasons Why CosmoFlow on a Cray System is a Big Deal

by Leave a Comment

Today, Cray, NERSC (the National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory) and Intel announced the results of a three-way collaboration around CosmoFlow, a deep learning 3D convolutional neural network (CNN) that can predict cosmological parameters with unprecedented accuracy using the Intel-powered Cray® XC™ series “Cori” supercomputer at NERSC. Supercomputers are unique in their ability to be instruments of discovery for problems on the smallest and largest of scales — from subatomic scale to the cosmos. Cosmologists who study the origin, evolution and eventual fate of the universe use a combination of empirical observations and theoretical computer simulations to define and refine a ...

Can LS-DYNA Scale Any Higher?

by 1 Comment

Processing and memory bottlenecks can run but they can’t hide. Not indefinitely, at least. And especially not when four technology leaders combine efforts against them. Cray, Livermore Software Technology Corporation (LSTC), the National Center for Supercomputing Applications (NCSA) and Rolls-Royce are partnering on an ongoing project to explore the future of implicit finite element analyses of large-scale models using LS-DYNA, a multiphysics simulation software package, and Cray supercomputing technology. As the scale of finite element models — and the systems they run on — increase, so do scaling issues and the amount of time it takes to run a model. Understanding that, ultimately, only time and resource constraints limit the size ... [ Read More ]

Inside Isambard — the World’s First Production Arm Supercomputer

by Leave a Comment

The Isambard Project, a GW4 Alliance initiative, recently disclosed the latest results from its benchmarking of Arm-based processors for HPC, the first such results for dual socket Cavium ThunderX2 nodes. Prof. Simon McIntosh-Smith gave a talk at the Cray User Group (CUG) Conference in Stockholm on May 23, 2018, in which he described the results of a detailed performance comparison between Cavium™ ThunderX2® Arm®-based CPUs and the latest state-of-the-art Intel Skylake x86 processors. Results focused on the HPC codes that are most heavily used on the UK’s national supercomputer, ARCHER, and showed that for these kinds of workloads, ThunderX2 is competitive with the best x86 CPUs available today, but with a significant cost ...

How to Make Solving I/O Bottlenecks Look Easy

We live for a good customer challenge. And you can’t get a much better challenge than one that turns into a new product with broad application. The challenge came to us by way of Los Alamos National Laboratory (LANL) and the National Nuclear Security Administration (NNSA). LANL launched their “Trinity” supercomputer in 2015. Based on Cray® XC™ series architecture, Trinity is the first installation of the NNSA Simulation and Computing program’s initiative to develop and deploy a series of advanced technology systems. Together they’re exploring compute technology so they can provide platforms with higher performance for predictive capability — all while solving national security challenges. In short, NNSA and LANL are working ... [ Read More ]

Supercomputing Powers Clean Wind Energy

Dr. Lawrence Cheung and the team from GE Global Research are maximizing the power production of clean energy wind farms. As a clean, renewable energy source, wind power is unbeatable. Research studies show that wind, harnessed effectively, could meet all the world’s energy demands. But a gap still exists between potential and reality ... a gap that Lawrence Cheung and GE Global Research are working on closing. “We’re trying to understand what the wind is doing around the turbines, why it might not be getting enough power here or why it’s not efficient there." Dr. Cheung is a lead mechanical engineer at GE Global Research Center’s Aerothermal discipline. There, he studies wind and noise — elements critical to the design of wind ... [ Read More ]
