Simulating Shock Turbulence Interactions on Stampede II

In this special guest feature, Jorge Salazar from TACC writes that Researchers are using XSEDE supercomputers to better understand shock turbulence interactions. “We proposed that, instead of treating the shock as a discontinuity, one needs to account for its finite thickness as in real life which may be involved as a governing parameter in, for example, amplification factors,” Donzis said.

Supercomputing Galactic Winds with Cholla

Using the Titan supercomputer at Oak Ridge National Laboratory, a team of astrophysicists created a set of galactic wind simulations of the highest resolution ever performed. The simulations will allow researchers to gather and interpret more accurate, detailed data that elucidates how galactic winds affect the formation and evolution of galaxies.

HPC Innovation Excellence Award Showcases Physics-based Scientific Discovery

A collaboration that includes researchers from NERSC was recently honored with an HPC Innovation Excellence Award for their work on “Physics-Based Unsupervised Discovery of Coherent Structures in Spatiotemporal Systems.” The award was presented in June by Hyperion Research during the ISC19 meeting in Frankfurt, Germany.

Podcast: ExaStar Project Seeks Answers in Cosmos

In this podcast, Daniel Kasen from LBNL and Bronson Messer of ORNL discuss advancing cosmology through EXASTAR, part of the Exascale Computing Project. “We want to figure out how space and time get warped by gravitational waves, how neutrinos and other subatomic particles were produced in these explosions, and how they sort of lead us down to a chain of events that finally produced us.”

Job of the Week: Postdoctoral scholar position for terrestrial systems modeling at Jülich Supercomputing Centre

The Jülich supercomputing Centre in Germany is seeking a Postdoctoral scholar position in the field of terrestrial systems modeling. “You will setup and perform large scale terrestrial systems simulations over the European continent based on novel climate change scenarios and story lines. The simulation results will be analyzed using advanced data analytics technologies to inform various sectors in order to formulate adaptation strategies.”

NCSA to help build world’s most powerful geospatial system

NCSA has announced a new collaboration to produce digital elevation models (DEM) of the entire Earth, among other geospatial research projects. “This is the beginning of building a long-term strategic relationship between NGA and the University of Illinois, centered on high-performance computing and data analysis. The Blue Waters collaboration is the first of what we anticipate will be many years of research collaborations between NGA and Illinois faculty as well as NCSA.”

Exploring the Universe with the SKA Radio Telescope and CUDA

In this video, Wes Armour from the Oxford eResearch Centre discusses the role of GPUs in processing large amounts of astronomical data collected by the Square Kilometre Array and how CUDA is the best suited option for their signal processing software. “The massive computational power of modern day GPUs allows code to perform algorithms such as de-dispersion, single pulse searching and Fourier Domain Acceleration Searching in real-time on very large data-sets which are comparable to those which will be produced by next generation radio-telescopes such as the SKA.”

Video: Supercomputing Sediment Transport in Estuaries

In this video, Salme Cook from the University of New Hampshire describes how she is using NCSA’s Blue Waters supercomputer to model estuaries. One of the big challenges oceanographers face is the inability to observe their science directly. Cook is focused on modeling two particular estuaries in New Hampshire that are experiencing water quality degradation.

Video: HPC at CASC

CASC serves as LLNL’s window to the broader computer science, computational physics, applied mathematics, and data science research communities. In collaboration with academic, industrial, and other government laboratory partners, investigators conduct world-class scientific research and development on problems critical to national security. CASC applies the power of high-performance computing (HPC) and the efficiency of modern computational methods to the realms of stockpile stewardship, cyber and energy security, and knowledge discovery for intelligence applications.

Supercomputing Heat Transfer between 2D Electronic Components

Researchers are using XSEDE supercomputing resources in the search for new materials for power-efficient electronics. “Using a combination of calculations on XSEDE-allocated resources and lab experiments, a UCLA-led group showed that an atomistic model can explain and predict the transfer of heat between aluminum and black phosphorous, a highly anisotropic material with possible applications in future devices.”
