Base software environment for XENONnT, including Python 3 and data management tools.

Please see this page on the XENON wiki for more details.

The resulting environment is available as:

  • Singularity image under CVMFS. This can be used in interactive enviroments as well as OSG compute jobs The location is /cvmfs/singularity.opensciencegrid.org/opensciencegrid/osgvo-xenon:{version}. Source /opt/XENONnT/setup.sh to get the environment configured.
  • Source-able environment under CVMFS. This is mostly useful in interactive enviroments like Midway. Note that it assumes you are on a EL7 based host. The location is /cvmfs/xenon.opensciencegrid.org/releases/nT/{version} and each version contains a setup.sh script you can source to get the environment.
  • Docker image in DockerHub. This version can be useful if you want to extend the base_environment, or use the environment for example on your laptop. The location is opensciencegrid/osgvo-xenon:{version}
  • Singularity images available on https. This version is experimental. The location is https://xenon.isi.edu/images/

master and stable branches

Currently, the master branch is used for the "development" container, which always points to the master branch of cutax (note this only matters on hardcoded sites: Midway and the OSG login node for now). The stable branch has a tagged version of cutax.

Deployment

Deployment Overview

The base_environment is rebuilt and redeployed automatically upon git commits. Just like in XENON1T, we have a create-env script which does the majority of the work. The difference in XENONnT is that the create-env script is run in a Docker container. The build is taking place twice: once to build the Docker container with a deployment under /opt/XENONnT, and once to build the tarball for the CVMFS deployment under /cvmfs/xenon.opensciencegrid.org/releases/nT/.
