Next-generation Subsurface Flow Simulations on Titan

Simulations performed on Titan enable detailed tracking  of two fluid pahse systems during flow through porous media.

Researchers are using the Titan supercomputer to power next-generation subsurface flow simulations. Improved models could benefit carbon sequestration, contaminant transport, and oil recovery research.

Video: HPC for the Louisiana Coastal Master Plan


Zachary Cobell from ARCADIS-US presented this talk at the HPC User Forum. “As a global leader for designing sustainable coastlines and waterways, ARCADIS believes in developing multi-faceted, integrated solutions to restore, protect, and enhance sensitive coastal areas. We are working with the Army Corps and the state of Louisiana to design these projects with and from nature, in effect using nature as a dynamic engine.”

AMD Forms Radeon Technologies Group for Graphics & Immersive Computing

Raja Koduri, AMD

Today AMD announced the promotion of Raja Koduri to senior vice president and chief architect, Radeon Technologies Group, reporting to president and CEO Dr. Lisa Su. In his expanded role, Koduri is responsible for overseeing all aspects of graphics technologies used in AMD’s APU, discrete GPU, semi-custom, and GPU compute products.

Video: Stunning Simulation Shows Comet in the Solar Wind


In what has to be one of the most beautiful simulations I’ve ever seen, this video from the European Space Agency shows simulated interaction of solar winds with 67P/Churyumov-Gerasimenko, the famous comet targeted the Rosetta mission. “The simulated conditions represent those expected at 1.3 AU from the Sun, close to perihelion, where the comet is strongly active.”

NASA Charts Sea Level Rise

NASA visualization shows shifts in the Gulf Stream (in Blue). Yellow shows drops in Sea Levels while Orange shows increases.

“Sea level rise is one of the most visible signatures of our changing climate, and rising seas have profound impacts on our nation, our economy and all of humanity,” said Michael Freilich, director of NASA’s Earth Science Division. “By combining space-borne direct measurements of sea level with a host of other measurements from satellites and sensors in the oceans themselves, NASA scientists are not only tracking changes in ocean heights but are also determining the reasons for those changes.”

Pushing the Boundaries of Combustion Simulation with Mira


“Researchers at the U.S. Department of Energy’s Argonne National Laboratory will be testing the limits of computing horsepower this year with a new simulation project from the Virtual Engine Research Institute and Fuels Initiative (VERIFI) that will harness 60 million computer core hours to dispel those uncertainties and pave the way to more effective engine simulations.”

Podcast: Supercomputing the Human Heart

Different views of the reconstructed finite element (FE) model for the ovine mitral valve apparatus with anatomically accurate leaflets represented by shell elements.

Over at TACC, Jorge Salazar writes that new supercomputer simulations are helping doctors improve the repair and replacement of heart valves. “New supercomputer models have come closer than ever to capturing the behavior of normal human heart valves and their replacements, according to recent studies by groups including scientists at the Institute for Computational Engineering and Sciences (ICES) at The University of Texas at Austin and the Department of Mechanical Engineering atIowa State University.”

Ray Tracing with Embree Kernels using Intel Xeon Phi


The Embree kernel approach, using the Intel Xeon Phi coprocessor is applicable to many situations. The implementation can be tuned to the hardware available, using different vector widths and workloads per ray. With a flexible toolkit for rendering, applications can take advantage of the latest hardware acceleration to achieve maximum performance.

Materials Imaging and Data Sciences Converge at Oak Ridge Workshop


Oak Ridge National Lab recently hosted a Materials Imaging Workshop. Entitled “Big, Deep and Smart Data Analytics in Materials Imaging,” the workshop explored research opportunities and challenges arising as imaging and data sciences merge.

Video: Next-Gen Hurricane Prediction


“Since Hurricane Katrina made landfall in 20015, storm prediction technology has seen dramatic forward movement, from improved software to better use of observations and increased computing power – all aimed at giving emergency decision makers more time and specifics to help protect lives and property. The expert panelists in this Congressional Briefing outline research advances that have led to better forecasting of hurricane and tropical storm weather and impacts. And they spotlight research directions that hold promise for future improvements.”
