The Exascale Computing Project (ECP) core mission is to develop a capable exascale computing ecosystem that accelerates scientific discovery and supports addressing critical challenges in energy, Earth systems, materials, data, and national security. The nature of this mission has drawn a wide range of talented and successful scientists with diverse backgrounds to work together in new ways toward this goal. As we work together, we want to accelerate and leverage the agility that occurs in small teams — and scale it out to the HPC community.
