Exascale Computing Project (ECP) director Paul Messina recently confirmed the U.S. timeline for achieving exascale supercomputer performance will be accelerated by one year. The update has the U.S. fielding at least two exascale systems in the next seven years, with one high-performance computer (HPC) aiming for a 2022 delivery and a 2023 acceptance.
However, the other system is now targeting delivery in 2021 and acceptance in 2022, while the U.S. Department of Energy (DoE) has clarified the first HPC will use a novel architecture.
In addition, the original 10-year timeline provided three years after delivery of the machines for applications and software tuning, but now those operations will start during the final year of the ECP and continue after that. The updated timeline will increase the project's cost and power requirements.
"The benefit to offsetting a year is that we don't have to deal with two systems simultaneously," Messina says.
For the novel architecture, the DoE wants a larger-scale implementation, which Messina says could come from a mix of ideas--including sensors and interconnects--proposed by the PathForward project. "There are emerging processor architectures that seem quite promising--one would expect that there will be some fairly large systems with those processor architectures available within a couple years," Messina says.
