Purpose	Scientific research

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. The system is targeting 150–300 PFLOPS of performance at 10 MW of power. The computer will be finished in 2017, and moved to Oak Ridge in 2018 where it will replace the Titan supercomputer.

Each node will have over half a terabyte of coherent memory (high bandwidth memory + DDR4 SDRAM) which will be addressable by all CPUs and GPUs plus 800GB of non-volatile RAM that can be used as a burst buffer or as extended memory. The Power9 CPU's and Volta GPUs will be connected using NVIDIA's high speed NVLink. This allows for a heterogeneous computing model.
