Simulating the Earliest Generations of Galaxies with Enzo and Blue Waters

“Galaxies are complex—many physical processes operate simultaneously, and over a huge range of scales in space and time. As a result, accurately modeling the formation and evolution of galaxies over the lifetime of the universe presents tremendous technical challenges. In this talk I will describe some of the important unanswered questions regarding galaxy formation, discuss in general terms how we simulate the formation of galaxies on a computer, and present simulations (and accompanying published results) that the Enzo collaboration has recently done on the Blue Waters supercomputer. In particular, I will focus on the transition from metal-free to metal-enriched star formation in the universe, as well as the luminosity function of the earliest generations of galaxies and how we might observe it with the upcoming James Webb Space Telescope.”

ACM Announces George Michael Memorial HPC Fellowships

Today ACM announced the recipients of the 2016 ACM/IEEE George Michael Memorial HPC Fellowships. The fellowship honors exceptional PhD students throughout the world whose research focus is on high performance computing applications, networking, storage or large-scale data analytics using the most powerful computers that are currently available.

SimScale Integrates with Autodesk Fusion 360

Today SimScale in Germany announced a partnership with Autodesk, a leader in 3D design and fabrication software. The SimScale add-in for Autodesk Fusion 360 aims at improving the design engineering workflow between the design (CAD) and virtual testing phases (CAE). With the help of the add-in, users creating their 3D models in Autodesk Fusion 360 will be able to push their geometry directly to an existing CFD, FEA, or thermal analysis project on SimScale, where they can simulate it in the cloud.

Video: Combining Simulation & Experiment for Nanoscale 3-D Printing

In this video, ORNL researchers use supercomputers to simulate nanomanufacturing, the process of building microscopic devices atom by atom. Simulated here is the construction of a 250-nanometer 3-D cube by focused electron beam induced deposition.

High Performance 4K Video Storage, Editing and Rendering

Advancements in video technology have slowly pushed applications like video editing, video rendering and video storage editing into the High Performance Computing world. There are many different video editing programs that can cut, trim, re-sequence, and add sound, transitions and special effects to video. But with the introduction of 4K/8K video, a simple laptop isn’t powerful enough on its own anymore, especially for online editing.

Simulating Sea Ice Leads at DKRZ

Researchers at DKRZ are using supercomputers to better understand the movement of sea ice. “Sea ice is an important component of the Earth System, which is often being discussed in terms of integrated quantities such as Arctic sea ice extent and volume.”

Faster Route to Insights with Hardware and Visualization Advances from Intel

An eye-popping visualization of two black holes colliding demonstrates 3D Adaptive Mesh Refinement volume rendering on next-generation Intel® Xeon Phi™ processors. “It simplifies things when you can run on a single processor and not have to offload the visualization work,” says Juha Jäykkä, system manager of the COSMOS supercomputer. Dr. Jäykkä holds a doctorate in theoretical physics and also serves as a scientific consultant to the system’s users. “Programming is easier. The Intel Xeon Phi processor architecture is the next step for getting more performance and more power efficiency, and it is refreshingly convenient to use.”

STFC in the UK Opens New Technology Center

Businesses in the north west of the UK are being helped to develop new products faster and more cheaply. The advanced engineering technology centre was officially opened today at the Science and Technology Facility’s Council’s (STFC) Daresbury Laboratory in Cheshire. It will provide UK businesses of all sizes, including small start-ups, with affordable access to more than £2 million of advanced engineering technology, including advanced 3D printing and rapid prototype assistance.

Video: Discovering the Origin of Stars Through 3D Visualization

This visualization from David Ellsworth and Tim Sandstrom at NASA/AMES shows the evolution of a giant molecular cloud over 700,000 years. It ran on the Pleiades supercomputer using the ORION2 code developed at the University of California, Berkeley. It depicts how gravitational collapse leads to the formation of an infrared dark cloud (IRDC) filament in which protostars begin to develop, shown by the bright orange luminosity along the main and surrounding filaments.

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.”
