Virtual — registered attendees will receive a WebEx link

This workshop provides an introduction to using Livermore Computing's (LC) High Performance Computing (HPC) systems, geared at Data Science Summer Institute (DSSI) interns and tools most relevant to them. However, the first two parts also serve as a general introduction to using LC systems and are open to all who are interested. Topics include:

1. How to run and schedule jobs using SLURM on the LC Flash cluster
       - Description of Flash/Quartz architecture
       - Running tasks on Flash/Quartz login nodes
       - Running user jobs on Flash/Quartz compute nodes: batch & interactive
2. Getting help with LC systems
       - Online documentations
           * hpc.llnl.gov
           * LC Confluence pages
           * Other resources
       - LC Hotline
3. Installing applications on LC -- example tools:
       - How to use containers (Singularity)
       - How to install Tensorflow
       - How to install PyTorch
       - How to use Spack to install applications
       - Using R in JupyterHub

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

·  An LLNL OUN

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), or use RealVNC (see https://hpc.llnl.gov/software/visualization-software/vnc-realvnc ).

·  LC CZ RSA OTP token

In order to view and participate in these tutorials, one will have to download and install WebEx.
