Simulations of Hydrogen Ingestion Flashes in Giant Stars

“My team at the University of Minnesota has been collaborating with the team of Falk Herwig at the University of Victoria to simulate brief events in the lives of stars that can greatly affect the heavy elements they synthesize in their interiors and subsequently expel into the interstellar medium. These events are caused by the ingestion of highly combustible hydrogen-rich fuel into the convection zone above a helium burning shell in the deeper interior. Although these events are brief, it can take millions of time steps to simulate the dynamics in sufficient detail to capture subtle aspects of the hydrogen ingestion. To address the computational challenge, we exploit modern multicore and many-core processors and also scale the simulations to run efficiently on over 13,000 nodes of NSF’s Blue Waters machine at NCSA.”

Rescale HPC Cloud to Foster Return of Supersonic Travel

Denver-based Boom Technology is leveraging Rescale’s cloud-based simulation and optimization system to enable a rebirth of supersonic passenger travel. “Rescale’s cloud platform is a game-changer for engineering. It gives Boom computing resources comparable to building a large on premise HPC center. Rescale lets us move fast with minimal capital spending and resources overhead,” Joshua Krall, Co-founder & CTO.

Podcast: Supercomputing Gels with Stampede

In this TACC Podcast, Jorge Salazar looks at how researchers are using the Stampede supercomputer to shed light on the microscale world of colloidal gels — liquids dispersed in a solid medium as a gel. “Colloidal gels are actually soft solids, but we can manipulate their structure to produce ‘on-demand’ transitions from liquid-like to solid-like behavior that can be reversed many times,” Zia said. Zia is an Assistant Professor of Chemical and Biomolecular Engineering at Cornell University.

Flow Science Expands to Latin America

Today Flow Science announced that it has formed a new subsidiary, Flow Science Latin America SAS (FSLA), to sell and support Flow Science’s suite of computational fluid dynamics software products throughout Central and South America.

Supercomputing Complex Diesel Injection Mist at Army Research Lab

The ability to study complex interactions inside a diesel engine gives Army scientists a new perspective that may help design more fuel efficient and effective engines. Using state-of-the-art supercomputers, Army scientist Dr. Luis Bravo led efforts to create simulations highlighting the first year of his project, allowing them to investigate the jet fuel spray breakup process with microsecond time fidelity and sub-millimeter resolution, while generating petabytes of data.

Video: What’s New with Fortran?

Originally developed by IBM in the 1950s for scientific and engineering applications, Fortran came to dominate this area of programming early on and has been in continuous use for over half a century in computationally intensive areas such as numerical weather prediction, finite element analysis, computational fluid dynamics, computational physics and computational chemistry. It is a popular language for high-performance computing and is used for programs that benchmark and rank the world’s fastest supercomputers.
