WriteToCVMFS

How to write to /cvmfs/lz.opensciencegrid.org

# lzsoft9.hep.wisc.edu is the cvmfs writer and only accessible through the hep.wisc.edu network
# login to lzsoft9.hep.wisc.edu via login.hep.wisc.edu
ssh username@login.hep.wisc.edu
# then
ssh lzsoft9.hep.wisc.edu

# edit in /srv/cvmfs
cd /srv/cvmfs

#  E.g.Write an empty file to the parent directory (don't follow it literally)
touch myFile.txt

# Eventually (within a couple hours) this change will propagate to /cvmfs/lz.opensciencegrid.org

Build Geant4

# Only login0[1-6].hep.wisc.edu are accessible from outside networks
ssh login.hep.wisc.edu

# From there, login to lzsoft.hep.wisc.edu (this is the cvmfs writer)
ssh lzsoft.hep.wisc.edu

# gcc 4.8.4, cmake 3.3, and Xerces-c are required.
# They can be found here:
# /cvmfs/sft.cern.ch/lcg/releases/LCG_79/gcc/4.8.4/x86_64-slc6
# /cvmfs/lz.opensciencegrid.org/cmake
# /cvmfs/lz.opensciencegrid.org/xerces-c
# For compatibility with BACCARAT, we compile with CLHEP 2.3.4.4, found here:
# /cvmfs/lz.opensciencegrid.org/CLHEP/2.3.4.4


# Make sure your path is set to these
export PATH=$PATH:/usr/bin:/bin:/usr/local/bin:/sbin:/usr/sbin

# The /scratch is where you would build the package before installing on cvmfs
# This prevents unnecessary build files getting into cvmfs
mkdirp -p /scratch/$USER
cd /scratch/$USER

# Get the Geant4 tarball from 
# http://geant4.web.cern.ch/geant4/support/download.shtml
