Jack Wells is the Director of Science for the Oak Ridge Leadership Computing Facility (OLCF).
In this video from the 2018 OpenPOWER Summit in Las Vegas, Jack Wells from ORNL presents: Powering the Road to National HPC Leadership.
The Summit supercomputer coming to Oak Ridge is the next leap in leadership-class computing systems for open science. With Summit we will be able to address, with greater complexity and higher fidelity, questions concerning who we are, our place on earth, and in our universe.
Summit will deliver more than five times the computational performance of Titan’s 18,688 nodes, using only approximately 4,600 nodes when it arrives in 2018. Like Titan, Summit will have a hybrid architecture, and each node will contain multiple IBM POWER9 CPUs and NVIDIA Volta GPUs all connected together with NVIDIA’s high-speed NVLink. 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 I/O throughput, the nodes will be connected in a non-blocking fat-tree using a dual-rail Mellanox EDR InfiniBand interconnect.
In this time-lapse video, engineers install the first racks of the Summit supercomputer at Oak Ridge National Lab.
Upon completion, Summit will allow researchers in all fields of science unprecedented access to solving some of the world’s most pressing challenges.
Jack Wells is the Director of Science for the Oak Ridge Leadership Computing Facility (OLCF), a DOE Office of Science national user facility, and the Titan supercomputer, located at Oak Ridge National Laboratory (ORNL). Wells is responsible for the scientific outcomes of the OLCF’s user programs.
Wells has previously lead both ORNL’s Computational Materials Sciences group in the Computer Science and Mathematics Division and the Nanomaterials Theory Institute in the Center for Nanophase Materials Sciences. Prior to joining ORNL as a Wigner Fellow in 1997, Wells was a postdoctoral fellow within the Institute for Theoretical Atomic and Molecular Physics at the Harvard-Smithsonian Center for Astrophysics.
Wells has a Ph.D. in physics from Vanderbilt University, and has authored or co-authored over 80 scientific papers and edited 1 book, spanning nanoscience, materials science and engineering, nuclear and atomic physics computational science, applied mathematics, and text-based data analytics.
In this video from SC17, Ken King from IBM describes how new Power9 compute nodes will power the next generation of the world’s most powerful Coral supercomputers at ORNL and LLNL.
