Podcast: Will the ExaSky Project be First to Reach Exascale?

In this Lets Talk Exascale podcast, Katrin Heitmann from Argonne describes how the ExaSky project may be one of the first applications to reach exascale levels of performance. “Our current challenge problem is designed to run across the full machine [on both Aurora and Frontier], and doing so on a new machine is always difficult,” Heitmann said. “We know from experience, having been first users in the past on Roadrunner, Mira, Titan, and Summit; and each of them had unique hurdles when the machine hit the floor.”

Supercomputing Planet Formation at SDSC

Researchers are using a novel approach to solving the mysteries of planet formation with the help of the Comet supercomputer at the San Diego Supercomputer Center on the UC San Diego campus. The modeling enabled scientists at the Southwest Research Institute (SwRI) to implement a new software package, which in turn allowed them to create a simulation of planet formation that provides a new baseline for future studies of this mysterious field. “The problem of planet formation is to start with a huge amount of very small dust that interacts on super-short timescales (seconds or less), and the Comet-enabled simulations finish with the final big collisions between planets that continue for 100 million years or more.”

Simulating the Earth’s mysterious mantle

Scientists are taking advantage of an $2.5 million NSF grant to develop a new framework for integrated geodynamic models that simulate the Earth’s molten core. “Most physical phenomena can be described by partial differential equations that explain energy balances or loss,” said Heister, an associate professor of mathematical sciences who will receive $393,000 of the overall funding. “My geoscience colleagues will develop the equations to describe the phenomena and I’ll write the algorithms that solve their equations quickly and accurately.”

Dr. Alice-Agnes Gabriel from LMU wins Ada Lovelace Award for HPC

Dr. Alice-Agnes Gabriel from LMU is the winner of the 2020 PRACE Ada Lovelace Award for HPC for her outstanding contributions to HPC in Europe. “Dr. Alice-Agnes Gabriel uses numerical simulations coupled to experimental observations to increase our understanding of the underlying physics of earthquakes. The work includes wide scales and can improve our knowledge and safety against these natural phenomena.” says Núria López, Chair of the PRACE Scientific Steering Committee.

Altair Acquires newFASANT for High-Frequency Electromagnetics

Today Altair announced the acquisition of newFASANT, offering leading technology in computational and high-frequency electromagnetics. “By combining its people and software into our advanced solutions offerings, we are clearly emerging as the dominant player in high-frequency electromagnetics – technology that is critical for solving some of the world’s toughest engineering problems.”

Mapping Disasters with Artificial Intelligence

In this Chip Chat podcast, Intel’s Alexei Bastidas describes the technology behind making maps from satellite images. “Good maps rely on good data. The Red Cross’ Missing Maps Project leverages AI to provide governments and aid workers with the tools they need to navigate disasters like hurricanes and floods. Using a wealth of satellite imagery and machine learning, the Missing Maps Project is working to make villages, roads, and bridges more accessible in the wake of devastation.”

SC19 Invited Talk: OpenSpace – Visualizing the Universe

Anders Ynnerman from Linköping University gave this invited talk at SC19. “This talk will present and demonstrate the NASA funded open source initiative, OpenSpace, which is a tool for space and astronomy research and communication, as well as a platform for technical visualization research. OpenSpace is a scalable software platform that paves the path for the next generation of public outreach in immersive environments such as dome theaters and planetariums.”

XSEDE Supercomputers Advance Skin Cancer Research

In this TACC podcast, UC Berkeley scientists describe how they are using powerful supercomputers to uncover the mechanism that activates cell mutations found in about 50 percent of melanomas. “The study’s computational challenges involved molecular dynamics simulations that modeled the protein at the atomic level, determining the forces of every atom on every other atom for a system of about 200,000 atoms at time steps of two femtoseconds.”

Video: Using Supercomputers to Explore the Earth’s Crust

In this video, Mark Lindsay from the University of Western Australia describes how his research enables Australia’s mining industry to efficiently explore for important mineral deposits called e-minerals once associated with electric cars and lithium-ion batteries. His research interests include complexities of uncertainty and ambiguity in 3D geological and mineral exploration modelling, and the process and psychology of data interpretation.

Supercomputing a Neutron Star Merger

Scientists are getting better at modeling the complex tangle of physics properties at play in one of the most powerful events in the known universe: the merger of two neutron stars. “We’re starting from a set of physical principles, carrying out a calculation that nobody has done at this level before, and then asking, ‘Are we reasonably close to observations or are we missing something important?’” said Rodrigo Fernández, a co-author of the latest study and a researcher at the University of Alberta.
