A 3-D rendering shows simulated solar convection realized at different rotation rates. Regions of upflow and downflow are rendered in red and blue, respectively. As rotational influence increases from left (non-rotating) to right (rapidly rotating), convective patterns become increasingly more organized and elongated. Understanding the sun's location along this spectrum represents a major step toward understanding how it sustains a magnetic field.

The Argonne-led <em>Multiscale Coupled Urban Systems</em> project aims to help city planners better examine complex systems, understand the relationships between them and predict how changes will affect them. The ultimate goal is to help officials identify the best solutions to benefit urban communities. (Image by Argonne National Laboratory.)
Exascale and the city

The Argonne-led Multiscale Coupled Urban Systems project will create a computational framework for urban developers and planners to evaluate integrated models of city systems and processes. With this framework, city planners can better examine complex systems, understand the relationships between them and predict how changes will affect them. It can ultimately help officials identify the best solutions to benefit urban communities.

Recently, 70 scientists — graduate students, computational scientists, and postdoctoral and early-career researchers — attended the fifth annual Argonne Training Program on Extreme-Scale Computing (ATPESC) in St. Charles, Illinois. Over two weeks, they learned how to seize opportunities offered by the world’s fastest supercomputers. (Image by Argonne National Laboratory.)
Leaning into the supercomputing learning curve

Scientists need to learn how to take advantage of exascale computing. This is the mission of the Argonne Training Program on Extreme-Scale Computing (ATPESC), which held its annual two-week training workshops over the summer.

This shows the HACC cosmology simulation, which combines high spatial and temporal resolution in a large cosmological volume. The high temporal resolution tracks the evolution of structures in great detail and correlates formation histories to the environments in which the structures form.

Cartography of the cosmos

There are hundreds of billions of stars in our own Milky Way galaxy, interspersed with all manner of matter, from the dark to the sublime. This is the universe that Argonne researcher Salman Habib is trying to reconstruct, structure by structure, combining telescope surveys with next-generation data analysis and simulation techniques currently being primed for exascale computing.

Above: 3-D structures of adenine riboswitch RNA calculated using RS3D, a computer program that runs on the supercomputer Mira. RNAs like adenine riboswitch are biological structures found in all human cells; they help control how and when genes are expressed. Some of these structures are linked to cancer and other diseases, and by using RS3D to learn more about them, researchers can better understand how associated diseases evolve, which could lead to better treatments or cures.

Tackling disease in three dimensions: supercomputers help decode RNA structure

In collaboration with staff from the Argonne Leadership Computing Facility, researchers at the National Cancer Institute have perfected a technique that accurately computes the 3-D structure of RNA sequences. This method, which relies on a computer program known as RS3D and supercomputer Mira gives researchers studying cancer and other diseases structural insights about associated RNAs that can be used to advance computer-assisted drug design and development.
