> Summit is a supercomputer being developed by IBM for use at Oak Ridge National Laboratory. The system will be powered by IBM's POWER9 CPUs and Nvidia Volta GPUs.
Summit is supposed to be finished in 2017, though. I'm quite surprised this is possible since the Volta architecture has only just now been announced.
Supercomputers have very long planning and development cycles. So do GPUs and CPUs. The contract specified chips that didn't yet exist (Volta and POWER9) as much more than codenames on a roadmap.
