9:00am–4:30pm, Tuesday and Wednesday; 10:00–11:00am Thursday
Virtual — attendees will receive a WebEx link


This 2+ -day workshop covers the "getting started" basics for using Livermore Computing's (LC) High Performance Computing (HPC) systems. It is intended to help LLNL summer interns (and others) get up to speed quickly with using LC's supercomputers. Topics include:

  • Introduction to parallel computing
  • Overview of LC's HPC resources and computing environment
  • Using LC's HPC Linux clusters (with hands-on exercises)
  • Running jobs and using LC's Moab/SLURM batch systems (with hands-on exercises)
  • Introductory parallel programming with MPI (with hands-on exercises)
  • Introductory parallel programming with OpenMP (with hands-on exercises)
  • Debugging serial and parallel applications using the TotalView debugger

The Agenda section below provides links to the workshop materials for detailed information.

What to Bring

Important: Viewers who wish to participate in hands-on exercises must have:

·  SSH software with X11 capability must be installed in order to connect to LC systems for the hands-on exercises. Mac systems will need XQuartz or something similar. Windows users will need to install an SSH client, such as X-Win32 (provided by LANDesk Management on LLNL systems).

·  LC CZ RSA OTP token – in some cases, this will be provided to you

Level/Prerequisites Some knowledge and experience with using Linux is required.
