CVM-FS software

CVMFS package is installed and configured on all nodes.
See CVMFS documentation for more information

There are a number of repositories with packages prepared for usage under varios platforms but mostly Alma9(EL9)

SFT

Information taken from /cvmfs/sft.cern.ch/README.md

PREQUESITES

A number of basic packages need to be present on your machine in order for the LCG releases to work. More information can be found at CERN's GitLab.

Usage

For most of our distributed software you can find both a Bash script (ending in .sh) as well as a C Shell script (ending in .csh). By using the source command in your local shell with these scripts you can change your current shell environment to use the software on CVMFS instead of your locally installed packages. These changes only last until you close the current terminal session.

Example

source /cvmfs/sft.cern.ch/lcg/views/LCG_107a/x86_64-el9-gcc14-opt/setup.sh

All packages under the LCG_107a view will become available for usage.

GEANT4

Information taken from /cvmfs/geant4.cern.ch/README

Usage

Geant 4 setup needs multiple componets, as such a script as the one below should be used
on ISSAF one can use:

source /software/alice/enable_cvmfs_g4

below the content of the script for reference:

#!/usr/bin/env bash

[[ "${BASH_SOURCE[0]}" -ef "$0" ]] && { echo "This script should be sourced not executed"; exit 1; }

Load package environment with:

/cvmfs/alice.cern.ch/bin/alienv enter O2Physics::daily-20250401-0000-1

Or to load the environment in current shell (or within the analysis scripts)

export O2PHYS_TAG=daily-20250401-0000-1 WORK_DIR="/cvmfs/alice.cern.ch" ALIBUILD_ARCH_PREFIX="el9-x86_64/Packages" DISABLE_GPU=1
