What Does it Mean to Summit?

Version 1

    Many consider the Summit as the highest point of attainment or aspiration. It’s that exhilarating feeling of knowing you have reached the pinnacle. Mount Everest is the highest summit on earth. It is a place at once both awe-inspiring and unforgiving. It is where people go to live out their most challenging aspirations and dreams. The mountain remains the pinnacle of human feat and a pursuit representative of the greatest passion and drive.

    Summit – The Next Peak in HPC

    The Summit supercomputer, one of the two CORAL systems, will deliver the next leap in leadership-class computing systems for open science. With Summit, the supercomputing community will be able to address, with greater complexity and higher fidelity, questions concerning who we are, our place on earth, and in our universe.

    The Summit supercomputer will deliver more than five times the computational performance of its predecessor Titan.  Summit will have a hybrid architecture, and each compute node will contain dual IBM POWER9 CPUs and multiple NVIDIA Volta GPUs. Each node will have over half a terabyte of coherent memory (high bandwidth memory + DDR4) addressable by all CPUs and GPUs plus 800GB of non-volatile RAM that can be used as a burst buffer or as extended memory. To provide a high rate of data throughput, the nodes will be connected in a non-blocking fat-tree topology using a dual-rail Mellanox EDR InfiniBand interconnect for both storage and inter-process communications traffic which delivers both 200Gb/s bandwidth between nodes and in-network computing acceleration for communications frameworks such as MPI and SHMEM/PGAS.
