OpenFOAM containers at Pawsey: Setup

What we’ll need?

• You should be able to connect to Zeus via ssh
• We’ll be using scripts and exercises from a Git Repository.

Confirm you have access on your laptop to the command line.

• Linux/Mac users should require no setup. We recommend the usage of native terminal applications.
• Windows users require software for SSH connections prior to attending the workshop:
  • “MobaXTerm” or “Visual Studio Code” are recommended.
• Info in our documentation: https://support.pawsey.org.au/documentation/display/US/Logging+in+with+SSH

Connecting to Zeus and Cloning the exercises

Steps for dealing with connection and cloning

Please do the following:

1. Open a linux terminal and ssh to zeus providing your credentials

    $ ssh user@zeus.pawsey.org.au

2. Create a directory for the training in /scratch and clone the repository

    zeus-1:~> mkdir -p $MYSCRATCH/pawseyTraining
    zeus-1:~> cd $MYSCRATCH/pawseyTraining
    zeus-1:pawseyTraining> git clone https://github.com/PawseySC/containers-openfoam-workshop-scripts.git
   

    Cloning into 'containers-openfoam-workshop-scripts'...

3. To shrink the prompt information (instead of displaying the user and the full current path) copy/paste the following variable set:

    espinosa@zeus-1:/scratch/pawsey0001/espinosa/pawseyTraining/containers-openfoam-workshop-scripts> PS1='\[$(ppwd)\]\h:${PWD/*\//}> '
