Groundbreaking Supercomputer Time Awarded to CITA's James Beattie for Astrophysical Research

In an exciting advancement for astrophysical research, James Beattie, a postdoctoral fellow at the Canadian Institute for Theoretical Astrophysics (CITA) and Princeton University, along with his team, has been granted nearly 100 million core-hours on one of Europe’s most advanced supercomputers, the SuperMUC-NG at the Leibniz Supercomputing Centre in Germany.

This remarkable allocation of computational power will enable Beattie to dive deep into two pioneering research projects focused on magnetic field generation in the violent phenomenon of merging binary neutron stars. This research is crucial for understanding the nature of magnetized turbulence, which often occurs at insane resolutions and is pivotal for cosmic events like supernovae and gamma-ray bursts.

To put the scale of this compute time into perspective, Beattie explains, "100 million core-hours is an astounding amount of computational time—it’s like running a program on your laptop non-stop for an hour. To envision what this means in terms of time, if I had started my calculations 11,000 years ago, they would be wrapping up just about now!" This analogy highlights just how monumental the task is, especially considering that domesticated cattle first appeared around 10,500 years ago.

Of the extensive computing resources granted, 20 million core-hours are dedicated to examining the Kelvin-Helmholtz dynamo, investigating how binary neutron stars generate powerful magnetic fields mere milliseconds before they collide. Collaborating with CITA faculty member Bart Ripperda, Beattie hopes to understand the rapid build-up of magnetic fields that can lead to spectacular gravitational wave emissions and bright radiative outbursts that are observable by telescopes. By zooming in on minute regions of just 10 meters, the researchers will simulate plasma behaviors that foster enormous magnetic field growth.

The second leg of Beattie's research is allocated a staggering 74 million core-hours to create what could become the largest compressible magnetohydrodynamic (MHD) turbulence simulation to date. This innovative work aims to explore magnetized turbulence, offering insights relevant to diverse fields such as star formation, the behavior of accretion disks, and the dynamics of plasma turbulence near Earth, particularly in the magnetosheath.

Beattie is particularly enthusiastic about the universal implications of their work. "Astrophysical processes like turbulence transcend beyond just our solar system; they are inherent to the very fabric of the universe," he emphasizes.

A common concern arises regarding how long it will take to see the results from such ambitious projects. However, Beattie reassures us: "No, thankfully! Thanks to the immense computing power of SuperMUC-NG, equivalent to about 350,000 individual computers, our work will be completed in just a few months. Although we anticipate creating around three petabytes of data from the turbulence simulations alone—which is about a million gigabytes—the post-simulation data analysis will definitely require extensive time and collaboration among experts in various fields."

This unprecedented computational allocation not only stands to deepen our understanding of cosmic phenomena but also underscores the importance of high-performance computing in unlocking the mysteries of the universe. Stay tuned for more updates on these thrilling projects as they unfold!
