Advancing Fusion Science with CGYRO using GPU-based Leadership Systems

Jeff Candy and Igor Sfiligoi from General Atomics gave this talk at the GPU Technology Conference. “Gyrokinetic simulations are one of the most useful tools for understanding fusion science. We’ll explain how we designed and implemented CGYRO to make good use of the tens of thousands of GPUs on such systems, which provide simulations that bring us closer to fusion as an abundant clean energy source. We’ll also share benchmarking results of both CPU- and GPU-Based systems.”

Video: Multi-GPU FFT Performance on Different Hardware Configurations

Kevin Roe from the Maui High Performance Computing Center gave this talk at the GPU Technology Conference. “We will characterize the performance of multi-GPU systems in an effort to determine their viability for running physics-based applications using Fast Fourier Transforms (FFTs). Additionally, we’ll discuss how multi-GPU FFTs allow available memory to exceed the limits of a single GPU and how they can reduce computational time for larger problem sizes.”

Epic HPC Road Trip Continues to NREL

In this special guest feature, Dan Olds from OrionX continues his Epic HPC Road Trip series with a stop at NREL in Golden, Colorado. “When it comes to energy efficient computing, NREL has to be one of the most advanced facilities in the world. It’s the first data center I’ve seen where their current PUE is shown on a LCD panel outside the door. When I was visiting, the PUE of the Day was 1.027 – which is incredibly low.”

TACC Powers Climate Studies with GRACE Project

Researchers are using powerful supercomputers at TACC to process data from Gravity Recovery and Climate Experiment (GRACE). “Intended to last just five years in orbit for a limited, experimental mission to measure small changes in the Earth’s gravitational fields, GRACE operated for more than 15 years and provided unprecedented insight into our global water resources, from more accurate measurements of polar ice loss to a better view of the ocean currents, and the rise in global sea levels.”

Video: Exascale Deep Learning for Climate Analytics

Thorsten Kurth Josh Romero gave this talk at the GPU Technology Conference. “We’ll discuss how we scaled the training of a single deep learning model to 27,360 V100 GPUs (4,560 nodes) on the OLCF Summit HPC System using the high-productivity TensorFlow framework. This talk is targeted at deep learning practitioners who are interested in learning what optimizations are necessary for training their models efficiently at massive scale.”

CosmoGAN Neural Network to Study Dark Matter

As cosmologists and astrophysicists delve deeper into the darkest recesses of the universe, their need for increasingly powerful observational and computational tools has expanded exponentially. From facilities such as the Dark Energy Spectroscopic Instrument to supercomputers like Lawrence Berkeley National Laboratory’s Cori system at NERSC, they are on a quest to collect, simulate, and analyze […]

DUG Opens the Doors for 250 PF Bubba Supercomputer in Houston

Today DownUnder GeoSolutions (DUG) opened its giant new data center in Skybox Houston. Touted to be one of the most powerful supercomputers on earth, the facility is home to the company’s geophysical cloud service, DUG McCloud. “DUG is offering a unique cloud product including compute, storage, geophysical software, and services, initially with a massive 250 PF of geophysically-configured compute ready to go,” said DUG’s Managing Director, Dr Matthew Lamont.

Video: Can FPGAs compete with GPUs?

John Romein from ASTRON gave this talk at the GPU Technology Conference. “We’ll discuss how FPGAs are changing as a result of new technology such as the Open CL high-level programming language, hard floating-point units, and tight integration with CPU cores. Traditionally energy-efficient FPGAs were considered notoriously difficult to program and unsuitable for complex HPC applications. We’ll compare the latest FPGAs to GPUs, examining the architecture, programming models, programming effort, performance, and energy efficiency by considering some real applications.”

Aerospace Moving Forward with Modeling and Simulation

In this special guest feature from Scientific Computing World, Gemma Church writes that the aerospace industry is stuck in the past – but it isn’t due to a lack of new simulation and modeling techniques. “While there have been incremental improvements, in terms of creating quieter and more fuel-efficient aeroplanes, there is not a lot of innovation coming in, compared to the last century when we created aeroplanes moving at the speed of sound and made air travel available to the masses.”

Design Work Completed for SKA Telescope Supercomputer

An international group of scientists led by the University of Cambridge has finished designing the ‘brain’ of the Square Kilometre Array (SKA), the world’s largest radio telescope. When complete, the SKA will enable astronomers to monitor the sky in unprecedented detail and survey the entire sky much faster than any system currently in existence. “We estimate SDP’s total compute power to be around 250 PFlops – that’s 25% faster than IBM’s Summit, the current fastest supercomputer in the world.”
