Running duqtools with prominence
This Tutorial uses docker to create runs, and prominence to submit runs with duqtools
Getting started
Needed Packages
- The first thing we need is to install duqtools, if you haven't done this yet you can install it via
pip install duqtools - We will also need access to the source of duqtools, it can be downloaded from https://github.com/duqtools/duqtools, This notebook was created with version
1.5.0of duqtools - docker
- We also need access to the following images (or equivalent):
jintrac-imas. which can be found here https://gitlab.eufus.psnc.pl/containerization/jintrac/jintrac-imas-installer
- We also need access to the following images (or equivalent):
- prominence, and we need to be logged in
Some example data
In this tutorial we will use example data, as IMAS is non-free you will have to get your IMAS data through your preferred supplier. We assume that the system is run with JINTRAC (since JINTRAC has a docker container available), and we use a simple JINTRAC template, which you are of course free to substitute for your own
shutil.rmtree('./example', ignore_errors=True)
os.mkdir('example')
# We assume that the duqtools source is available and that we are in the docs/examples folder
shutil.copytree('../../tests/test_data/template_model', 'example/template');
# Some imas data, substitute with your own, as we are not allowed to provide it
shutil.copytree('../../../containerized_runs/imasdb', 'example/imasdb');
# A silly script to support venvs
with open("example/entry.sh", "w") as f:
f.write("""#!/bin/bash
set -e
. /etc/profile.d/modules.sh
module load IMAS
module load fc2k
if [ -d .venv ]; then

st = os.stat('example/entry.sh')
os.chmod('example/entry.sh', st.st_mode | stat.S_IEXEC)
!chmod +x example/entry.sh
