Argonne Researchers to Share Scientific Computing Advances at SC20

November 9, 2020

Nov. 9, 2020 — Researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory will share their latest insights and advances in high performance computing (HPC) at SC20, the International Conference for High Performance Computing, Networking, Storage and Analysis. This year’s event will be held virtually Nov. 9–19, 2020.

Continuing the laboratory’s long history of participation in the SC conference series, more than 90 Argonne researchers will contribute to conference activities and studies on topics ranging from exascale computing and big data analysis to artificial intelligence (AI) and quantum computing.

“This year’s SC conference provides an opportunity to hear from experts about the array of new technologies being explored by researchers and the advances we are making in addressing the challenges raised by the emerging exascale era,” said Valerie Taylor, director of Argonne’s Mathematics and Computer Science division and Argonne Distinguished Fellow. “Through the many virtual panels, papers, posters and workshops, the scientific community can share their accomplishments and demonstrate how research is being used for scientific discovery and societal impact.”

The laboratory’s conference activities will include technical paper presentations, invited talks, workshops, ​“birds of a feather” sessions, panel discussions and tutorials. Some notable Argonne contributions are highlighted below. For the full schedule of the laboratory’s participation in the conference, visit Argonne’s SC20 webpage.
