The Scientific Impact of the Exascale Computing Project.

The recent arrival of the Frontier Supercomputer at Oak Ridge National Laboratory officially marked the dawn of the exascale computing era. Its successful deployment coincided with the culmination of the U.S. Department of Energy Exascale Computing Project (ECP), an ambitious, complex, and risky research and development effort that integrated contributions from a broad and diverse subset of the high-performance computing community. The success of ECP will ultimately be judged by the scientific and engineering advances that it enabled. This Special Issue is focused on showcasing early successes in the use of exascale resources to enable breakthroughs in key areas of science in engineering. [ABSTRACT FROM AUTHOR]
