RECORD-SETTING: THE INCOMING DOE CSGF CLASS For 2021-22, the Department of Energy Computational Science Graduate Fellowship (DOE CSGF) will induct a record- setting class of 32 new fellows attending institutions across the country, from the University of California, San Diego, to the University at Buffalo. Each will learn how to apply high-performance computing to problems of national importance, working in fields that include atmospheric science, condensed matter physics and quantum information.

WHAT WILL THAT MEAN GOING FORWARD? Recently I collaborated with my UC Berkeley research group One grand challenge in materials science is to solve the on simulating a prototype qubit-type system with more Schrödinger equation directly for an interacting materials BIGGER COMPUTING than 10,000 electrons, the largest-ever calculations done system. You can’t do it because it’s an exponentially growing on a material system using this level of fidelity. The work problem as you add more and more electrons to your system. was a finalist for the Gordon Bell prize last year. Two years But we can do a randomly sampled approach called quantum ago, I was part of a team that won the Gordon Bell prize for Monte Carlo. One ECP application will allow us to extend CHALLENGES work that involved training an artificial intelligence model to quantum Monte Carlo from smaller systems with up to one automatically detect extreme weather events like hurricanes hundred atoms to those with thousands of atoms using A DOE CSGF alumnus reflects on how Perlmutter and other new supercomputers and atmospheric rivers in climate datasets. QMCPACK. With a high-fidelity method on a system this size, will help researchers tackle larger science problems. you can now tackle things like defects and interfaces
