Best Use of HPC in Physical Sciences

The Event Horizon Telescope Collaboration teamed with the Texas Advanced Computing Center (TACC) to process an enormous amount of data to produce the first image of the supermassive black hole Sagittarius A*, the supermassive black hole at the center of the Milky Way. The image was made possible through a data-driven approach to astronomy that combines observations from eight radio telescopes around the world to form an Earth-scale interferometer, the Event Horizon Telescope, or EHT, specifically to probe black holes. The data analysis work was completed on TACC’s Frontera supercomputer, a Dell-Intel system.

NCAR has developed a GPU-based model, FastEddy, that can run weather forecasts at a resolution of just 5 meters (16 feet). FastEddy is a new resident-GPU microscale large-eddy simulation (LES) model coupled with the Weather Research and Forecasting (WRF) model. Trained primarily on NCAR’s Casper system, housing 64 Nvidia V100 GPUs, FastEddy has the capability to provide real-time weather hazard avoidance at the microscale level. FastEddy allows scientists to predict how weather and buildings in an urban environment affect drones and other small aerial vehicles. There are additional development efforts that aim to scale execution across up to 12,288 Nvidia V100 GPUs of the DOE’s Oak Ridge Leadership Computing Facility’s Summit architecture.

Purdue University researchers’ simulations with XSEDE systems at the Pittsburgh Supercomputing Center, San Diego Supercomputer Center, and Texas Advanced Computing Center reproduced sound waves to manage heat and stress in fluid flow. In a two-phase simulation, scientists used Bridges-2 at PSC (built by HPE) and then Comet at SDSC and Stampede2 at TACC (both Dell systems) to build and then run, respectively, a massive simulation showing how sound waves can be used to control and tune friction between the fluid and the walls of a container and transfer heat. The work holds promise in improving efficiency and reducing stress in power plants, electronics, and off-shore structures, lengthening service life and thus reducing production costs.
