Participating in the project as a co-investigator is Xingqiu Yuan, a software engineer in the Mathematics and Computer Science division at Argonne National Laboratory

E3SM, which is led by Sandia National Laboratories, will receive 1,250,000 node-hours on Frontier and 450,000 node-hours on Summit to model the Earth’s climatic systems. This is the first year that the INCITE awards have included allocations on Frontier, rated the world’s fastest supercomputer.

The multi-institutional team, which includes Sandia, Argonne, Lawrence Livermore, Los Alamos, Oak Ridge and Pacific Northwest national laboratories, will conduct simulations aimed at estimating the climate’s sensitivity to elevated greenhouse gases.

“Two factors make this a golden opportunity for such unprecedented simulations,” Yuan said. ​“The first is the advent of exascale machines that can perform multiyear simulations, and the second is the unique storm-resolving configurations of E3SM that our team has developed.”

Indeed, E3SM is one of the first global storm-resolving global models designed to run efficiently on DOE’s upcoming exascale supercomputers.

The INCITE program began in 2003 with the aim of accelerating scientific discoveries by supporting compute- and data-intensive projects at the Oak Ridge and Argonne leadership computing facilities. The ​“Energy Exascale Earth System Model” project is one of 56 high-impact computational science projects awarded supercomputing time under the 2023 INCITE program.

Project fact sheets with summaries of all the 2023 INCITE projects are available here.

Jointly managed by the Argonne Leadership Computing Facility (ALCF) and the Oak Ridge Leadership Computing Facility (OLCF), the INCITE program is the primary means by which the facilities fulfill their mission to advance open science by providing the scientific community with access to their powerful supercomputing resources.
