Dr. Tao's research has been fortunate to utilize several state-of-the-art production HPC systems (supercomputers) across the U.S. Up till now, Dr. Tao's group has been using Frontera at Texas Advanced Computing Center (TACC), Bridges at Pittsburg Supercomputing Center (PSC), Summit at Oak Ridge Leadership Computing Facility (OLCF), Cori at National Energy Research Scientific Computing Center (NERSC), Mira at Argonne Leadership Computing Facility (ALCF), for experimental research activities.
BIG RED 200 @ INDIANA UNIVERSITY
Dr. Tao's group has access to Big Red 200 at Indiana University. Big Red 200 is an HPE Cray EX supercomputer designed to support scientific and medical research, and advanced research in artificial intelligence, machine learning, and data analytics. Big Red 200 features
640 compute nodes, each equipped with 256 GB of memory and two 64-core, 2.25 GHz, AMD EPYC 7742 processors;
64 GPU nodes, each with 256 GB of memory, a single 64-core, 2.0 GHz, AMD EPYC 7713 processor, and four NVIDIA A100 GPUs;
A theoretical peak performance (Rpeak) nearly 7 PFLOPS.
KAMIAK CLUSTER @ WASHINGTON STATE UNIVERSITY
Dr. Tao's group has a dedicated node at Kiamiak cluster at WSU. This node is equipped with:
two 28-core Intel 6238 CPUs
