The U.S. D.O.E. Exascale Computing Project – Goals and Challenges

Paul Messina from Argonne gave this Invited Talk at SC17. "Balancing evolution with innovation is challenging, especially since the ecosystem must be ready to support critical mission needs of DOE, other Federal agencies, and industry, when the first DOE exascale systems are delivered in 2021. The software ecosystem needs to evolve both to support new functionality demanded by applications and to use new hardware features efficiently. We are utilizing a co-design approach that uses over two dozen applications to guide the development of supporting software and R&D on hardware technologies as well as feedback from the latter to influence application development.
