Environment

Bash

There are several useful environment variables provided by SLURM when submitting jobs:

 SLURM_JOB_ID - Job ID.
 SLURM_JOB_NAME - Job name.
 CUDA_VISIBLE_DEVICES - Specifies the GPU devices for the job allocation.
 TMPDIR - Local temporary directory reserved for the job. This should be used instead of /tmp. 
 

Refer to SLURM docs for complete list.

Python

If you need to use a different version of python than the default one installed with node OS you can use pre-installed versions found at:

/opt/python

If you need some specific version not found in this directory please contact the AIC administrators.

Virtual environment

The recommended way is to use python through a virtual environment. You need to decide which PYTHON_VERSION you want to use and where do you want to store your virtual environment (VENV_PATH). Then you can create it:

/opt/python/<PYTHON_VERSION>/bin/python3 -m venv <VENV_PATH>

You need to activate the environment before you actually use it:

source <VENV_PATH>/bin/activate

Then you should be able to use the python version of your choice. More about virtual environments can be found here
