Creating the venv

Download the sophia-venv.sh script and run it like this:

$ ./sophia-venv.sh <venv-name>
...

After a few minutes, you will have a <venv-name> folder with a GPAW installation inside.

Using the venv

In the following, we will assume that your venv folder is ~/venv1/. The venv needs to be activated like this:

$ source ~/venv1/bin/activate

and you can deactivate it when you no longer need to use it:

$ deactivate

You will want the activation to happen automatically for the jobs you submit to Sophia. Here are three ways to do it:

  1. If you always want to use one venv then just put the activation command in your ~/.bashrc.

  2. If you only want jobs running inside a certain folder to use the venv, then add this to your ~/.bashrc:

    if [[ $SLURM_SUBMIT_DIR/ = $HOME/project-1* ]]; then
        source ~/venv1/bin/activate
    fi
    

    Now, SLURM-jobs submitted inside your ~/project-1/ folder will use the venv.

  3. Use the “automatic discovery of venv’s” feature of MyQueue:

    $ cd ~/project-1
    $ ln -s ~/venv1 venv
    $ mq submit job.py
    

    MyQueue will look for venv/ folders (or soft-links as in the example) in one of the parent folders and activate the venv automatically when your job starts running.
