The vision of the Exascale Computing Project, initiated in 2016 as a formal U.S. Department of Energy project executing through 2022, is to accelerate innovation with exascale simulation and data science solutions. After a brief overview of this, we will give illustrative examples on how the ECP teams are leveraging, exploiting, and advancing accelerated-node software technologies and applications on hardware such as the powerful GPUs provided by NVIDIA. We will summarize best practices and lessons learned from these accelerated-node experiences along with ECP's plans moving into the exascale era, which is on the now near-term horizon.
These solutions will enhance U.S. economic competitiveness, change our quality of life, and strengthen our national security. ECP's mission is to deliver exascale-ready applications and solutions that address currently intractable problems of strategic importance and national interest; create and deploy an expanded and vertically integrated software stack on DOE HPC exascale and pre-exascale systems, defining the enduring US exascale ecosystem; and leverage U.S. HPC vendor research activities and products into DOE HPC exascale systems. The project is a joint effort of two DOE programs: the Office of Science Advanced Scientific Computing Research Program and the National Nuclear Security Administration Advanced Simulation and Computing Program. ECP's RD&D activities, which encompass the development of applications, software technologies, and hardware technologies and architectures, is carried out by over 100 small teams of scientists and engineers from the DOE national laboratories, universities, and industries.
