Example application#

When configuring your CVMFS session, select the repositories that are relevant to your research field. For example:

For High-Energy Physics:#

LHC Experiments: Use your collaboration's repository (atlas.cern.ch, cms.cern.ch, alice.cern.ch, lhcb.cern.ch)
General software: Include sft.cern.ch for compilers and libraries
Configuration: Always include cvmfs-config.cern.ch

For Neutrino Physics:#

Long-baseline: dune.opensciencegrid.org, nova.opensciencegrid.org
Short-baseline: uboone.opensciencegrid.org, minerva.opensciencegrid.org
Toolkits: larsoft.opensciencegrid.org for LArTPC experiments

For Astrophysics/Cosmology:#

icecube.opensciencegrid.org (neutrino astronomy)
spt.opensciencegrid.org (cosmic microwave background)
sw.lsst.eu (optical astronomy)
lz.opensciencegrid.org (dark matter searches)

General Scientific Computing:#

sft.cern.ch - Comprehensive scientific software stack
oasis.opensciencegrid.org - OSG community software
grid.cern.ch - Grid computing tools

You can always add more repositories later by creating a new persistent image, but starting with the correct set will save you time and storage space.
