SIAM CSE21: Hands-On Learning with the Summit Supercomputer
Thursday, March 4, 2021
2:15 – 5:55 PM (CST)

Deadline to apply: February 17, 2021

As part of the Broader Engagement (BE) program at SIAM CSE21, the Oak Ridge Leadership Computing Facility (OLCF) will hold a hands-on training with the Summit supercomputer. Participants will learn about the Summit architecture, learn how research teams write programs for and run workloads on Summit, and get to work through fun challenge problems on their own on the Ascent training system (basically 1 cabinet of Summit). Come discover what it’s like to use one of the most powerful computers ever built!


  • Laptop/desktop with ssh client (to log in to remote system)
  • Basic familiarity with UNIX/Linux (e.g., to navigate the file system)
  • Familiarity with a command line text editor (e.g., vim, emacs, nano)

  • During the Tutorial
    This tutorial is meant to deliver relevant high-performance computing (HPC) knowledge to participants with a wide range of previous experience in computational science through hands-on examples on one of the world’s most powerful supercomputers. We will begin with a short presentation describing the system architecture as well as a brief overview of the components commonly used on HPC systems (e.g., resource scheduler, job launcher). Afterward, we will move into the main hands-on session where attendees will get to “choose their own adventure” by selecting several self-guided challenge problems to complete based on their experience level and/or interests. The challenge problems will span a wide range of topics, from introductory/beginner material (e.g., walking through a basic workflow: set up programming environment, compile, request resources with batch scheduler, launch executable with job launcher) to exploring different methods of programming GPUs (e.g., CUDA, HIP, OpenACC, OpenMP offloading, etc.). Staff from the Oak Ridge Leadership Computing Facility (OLCF) will work with attendees to give guidance and answer questions along the way. So whether a participant typically sits at a workstation and would like to learn about using HPC clusters, or they are an experienced user of HPC systems and would like to add skills to their existing HPC tool belt, this tutorial will provide relevant content chosen by the participants to fit their needs/curiosities.

    If you would like to participate, please register below by February 17, 2021. Then, 1 week before the event, we will invite the registered participants to request accounts on Ascent.
