The U.S Department of Energy’s Exascale Computing Project (ECP) is a multi-lab initiative aimed at accelerating the delivery of a capable exascale computing ecosystem that encompasses applications, system software, hardware technologies, architectures, and workforce development.

Researchers from the ALCF and across Argonne National Laboratory⁠—one of the six ECP core labs—are helping the project deliver on its goals. The laboratory has a strong presence on the ECP leadership team and has several researchers engaged in ECP projects and working groups in the areas of application development, software development, and hardware technology.

Through its collaborations with the ECP, ALCF researchers are helping to prepare a diverse set of scientific applications to run on Aurora, developing a robust software stack for future exascale system users, and validating and testing exascale hardware in advance of deployment. In support of these activities, an ALCF staff member manages the allocation program that awards ECP projects with computing time at DOE’s leadership computing facilities, allowing developers to test features and functionality at scale. As part of the ECP’s Training and Productivity effort, ALCF staff members organize and manage the annual Argonne Training Program on Extreme-Scale Computing (ATPESC).
