Summary edit
| Description |
English: A team led by P. K. Yeung, professor of aerospace engineering and mechanical engineering at the Georgia Institute of Technology, performs direct numerical simulations of turbulence using his team’s code, GPUs for Extreme-Scale Turbulence Simulations (GESTS). These simulations can accurately capture the details that arise from a wide range of scales.
In 2019, the team developed a new algorithm optimized for the IBM AC922 Summit supercomputer at the OLCF. With the new algorithm, the team reached a performance of less than 15 seconds of wall-clock time per time step for more than 6 trillion grid points in space—a new world record surpassing the prior state of the art in the field for the size of the problem. The illustration shows intricate flow structures in turbulence from a large simulation performed using 1,024 nodes on Summit. The lower right frame shows a zoom-in view of a high-activity region.
