Supercomputing Jet Noise for a Quieter World

Researchers at the University of Minnesota are using Argonne supercomputers to to look for new ways to reduce the noise produced by jet engines. Among the loudest sources of human-made noise that exist, jet engines can produce sound in excess of 130 decibels. “The University of Minnesota team developed a new method based on input-output analysis that can predict both the downstream noise and the sideline noise. While it was thought that the sideline noise was random, the input-output modes show coherent structure in the jet that is connected to the sideline noise, such that it can be predicted and controlled.”

HPC Reveals Glacial Flow

In this special guest feature from Scientific Computing World, Robert Roe looks at research from the University of Alaska that is using HPC to change the way we look at the movement of ice sheets. “The computational muscle behind this research project comes from the UAF’s Geophysical Institute which houses two HPC systems ‘Chinook’, an Intel based cluster from Penguin Computing and ‘Fish’ a Cray system installed in 2012 based on the Cray XK6m-200 that uses AMD processors.”

Job of the Week: Visualization Specialist at Pawsey Centre in Australia

The Pawsey Supercomputing Centre in Australia is seeking a Visualization Specialist in our Job of the Week. “As a member of the Data and Visualization team at the Pawsey Supercomputing Centre, the Visualization Specialist will support services related to visualization including providing guidance, expert advice and helping users in designing and implementing analysis and visualization workflows.”

Podcast: Mapping DNA at Near-Atomic Resolution with Cryo-EM

In this podcast, Berkeley Lab’s Eva Nogales describes how her team is using a new imaging technology that is yielding remarkably detailed 3-D models of complex biomolecules critical to DNA function. Using cryo-electron microscopy (cryo-EM), Nogales and her colleagues have resolved the structure at near-atomic resolutions of a human transcription factor used in gene expression and DNA repair.

Mapping the Brain with the Theta Supercomputer

Researchers are using the Theta supercomputer at Argonne to map the intricate layout of brain neurons. “The basic goal is simple — would like to be able to image all of the neurons in the brain — but the datasets from X-rays and electron microscopes are extremely large,” said Doga Gursoy, assistant computational scientist in the X-Ray Science Division of Argonne’s Advanced Photon Source. They are at the tera- and petabyte scales. So we would like to use Theta to build the software and codebase infrastructure in order to analyze that data.”

Entering the Era of Simulation Driven Design

In this special guest feature, Robert Roe from Scientific Computing World reports from the European Altair Technology Conference and finds that simulation-driven design is taking center stage for the CAE industry. “Jim Scapa from Altair noted that Scapa noted that big data and the cloud will continue to play a significant role in the development and consumption of software and that manufacturing methods and materials science would continue to drive innovations – particularly in areas such as additive manufacturing and the design of composites.”

HPC Challenges in Simulating the World’s Most Powerful Tornados

“What makes this work significant is the use of supercomputing resources to produce simulations of supercells where data is saved with extremely high spatial and temporal resolution, and the use of visualization techniques (such as volume rendering and trajectory clouds) to produce video that exposes the highly variable flow features that occur throughout the life of the simulated storms. Some of these simulations contain long lived tornadoes producing near-surface winds exceeding 300 mph.”

Canada’s Biggest Radio Telescope to use CoolIT Systems Liquid Cooling

With support from CoolIT Systems with a custom Direct Liquid Cooling solution, the CHIME telescope will map out the entire northern sky each day, aiming to constrain the properties and evolution of Dark Energy over a broad swath of cosmic history. “The liquid cooled system consists of 256 rack-mounted General Technics GT0180 custom 4u servers housed in 26 racks managed by CoolIT Systems Rack DCLC CHx40 Heat Exchange Modules. The custom direct contact cooling loops manage 100% of heat generated by the single Intel Xeon E5 2620v3 CPUs and the Dual AMD FirePro S9300x2 GPUs, while simultaneously pulling heat from the ambient air into the liquid coolant loops.”
