Using Ai to detect Gravitational Waves with the Blue Waters Supercomputer

NASA researchers are using AI technologies to detect gravitational waves. The work is described in a new article in Physics Review D this month. “This article shows that we can automatically detect and group together noise anomalies in data from the LIGO detectors by using artificial intelligence algorithms based on neural networks that were already pre-trained to classify images of real-world objects,” said research scientist, Eliu Huerta.

Agenda Posted for April HPC User Forum in Tucson

The HPC User Forum has posted their speaker agenda for their upcoming meeting in Tucson. Hosted by Hyperion Research, the event takes place April 16-18 at Loews Ventana Canyon. “The April meeting will explore the status and prospects for quantum computing and HPC use of HPC for environmental research, especially natural disasters such as earthquakes and the recent California wildfires. As always, the meeting will also look at new developments in HPDA-AI, cloud computing and other areas of continuing interest to the HPC community. A special session will look at the growing field of processors and accelerators supporting HPC systems.”

Unstructured-Grid CFD Algorithms at NASA on Volta GPUs

Eric Nielsen from NASA gave this talk at SC17 in Denver. “In the field of computational fluid dynamics, the Navier-Stokes equations are often solved using an unstructured-grid approach to accommodate geometric complexity. Furthermore, turbulent flows encountered in aerospace applications generally require highly anisotropic meshes, driving the need for implicit solution methodologies to efficiently solve the discrete equations. To prepare NASA Langley Research Center’s FUN3D CFD solver for the future HPC landscape, we port two representative kernels to NVIDIA Pascal and Volta GPUs and present performance comparisons with a common multi-core CPU benchmark.”

NASA Goddard Boosts Discover Supercomputer to 5 Petaflops

CSRA Inc. has acquired another compute expansion under its High Performance Computing contract with NASA’s Goddard Space Flight Center. “This HPC expansion brings our compute capacity to over 50 petaFLOPS for all CSRA HPC contracts across the federal government,” said Sharon Hays, PhD., Director of CSRA’s HPC Center of Excellence. “This HPC expansion will help NASA researchers meet their mission objectives and bring a greater understanding of the earth’s climate system.”

Pointwise Announces Geode Geometry Kernel

Today Pointwise announced Project Geode, the company’s response to the NASA CFD Vision 2030 Study’s identification of the lack of CFD software access to geometry. As part of the announcement, Pointwise has opened beta testing of a geometry modeling kernel for computer-aided engineering (CAE) simulation software. “The kernel’s core geometry evaluation functions can provide all the functionality a CFD solver would need for tasks like mesh adaption and elevation of elements to higher-order. We are now seeking additional beta testers to validate this idea.”

Blue Waters Supercomputer Crunches Data from NASA’s Terra Satellite

Researchers are using the Blue Waters supercomputer at NCSA to process new data from NASA’s Terra Satellite. Approximately the size of a small school bus, the Terra satellite explores the connections between Earth’s atmosphere, land, snow and ice, ocean, and energy balance to understand Earth’s climate and climate change and to map the impact of human […]

Supermicro Powers Advanced Analytics at NASA NCCS

Today Supermicro announced that the company has partnered with the NASA Center for Climate Simulation (NCCS) to expand advanced computing and data analytics used to study the Earth, solar system and universe. Based on the combination of density, system performance and optimized cost, the Supermicro FatTwin-based solution brings an additional 1.56 PetaFlops to NASA researchers. The Rack Scale solution is factory integrated at Supermicro’s Silicon Valley headquarters to deliver optimal reliability and efficiency.

HPC Connects: Mapping Global Ocean Currents

In this video from the SC17 HPC Connects series, Dimitris Menemenlis from NASA JPL/Caltech describes how supercomputing enables scientists to accurately map global ocean currents. The ocean is vast and there are still a lot of unknowns. We still can’t represent all the conditions and are pushing the boundaries of current supercomputer power,” said Menemenlis. “This is an exciting time to be an oceanographer who can use satellite observations and numerical simulations to push our understanding of ocean circulation forward.”

Video: NASA Advanced Computing Environment for Science & Engineering

Rupak Biswas from NASA gave this talk at the Argonne Training Program on Extreme-Scale Computing. “High performance computing is now integral to NASA’s portfolio of missions to pioneer the future of space exploration, accelerate scientific discovery, and enable aeronautics research. Anchored by the Pleiades supercomputer at NASA Ames Research Center, the High End Computing Capability (HECC) Project provides a fully integrated environment to satisfy NASA’s diverse modeling, simulation, and analysis needs.”

Future HPC Leaders Gather at Argonne Training Program on Extreme-Scale Computing

Over at ALCF, Andrea Manning writes that the recent Argonne Training Program on Extreme-Scale Computing brought together HPC practitioners from around the world. “You can’t get this material out of a textbook,” said Eric Nielsen, a research scientist at NASA’s Langley Research Center. Added Johann Dahm of IBM Research, “I haven’t had this material presented to me in this sort of way ever.”
