WriteToCVMFS

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

# osggrid01.hep.wisc.edu is the cvmfs writer and only accessible through the hep.wisc.edu network
# login to osggrid01.hep.wisc.edu via lzlogin01.hep.wisc.edu
ssh username@lzlogin01.hep.wisc.edu
ssh osggrid01.hep.wisc.edu

cd /cvmfs/lz.opensciencegrid.org/
# Write an empty file to the parent directory (don't follow it literally)
 touch myFile.txt
 

Building a version of LUXSim

# login to osggrid01.hep.wisc.edu
ssh osggrid01.hep.wisc.edu

# Setup PATH, ROOTSYS, GEANT4
export ROOTSYS=/cvmfs/lz.opensciencegrid.org/ROOT/v5.34.32/slc6_gcc44_x86_64/root
export PATH=${ROOTSYS}/bin:/sbin:/usr/sbin:/usr/bin:/bin:/usr/local/bin
export LD_LIBRARY_PATH=${ROOTSYS}/lib:/lib64:/usr/lib64:/lib:/usr/lib
source /cvmfs/lz.opensciencegrid.org/geant4/etc/geant4env.sh

# go to LUXSim directory
cd /cvmfs/lz.opensciencegrid.org/LUXSim

# e.g. I will install the latest version of LUXSim
# Note that <username> and <passwd> for LUXSim svn repo should be obtained by following instructions given in the page below:
# http://teacher.pas.rochester.edu:8080/wiki/bin/view/Lux/UsageSVN

svn checkout --username <username> --password <passwd> svn://xenophile.case.edu/LUXSim latest

# Find the revision number of latest
cd latest/
RevNum=svn info | awk '/Revision/ {print "r"$2}'

# Organize the directory by renaming latest to revision number
cd /cvmfs/lz.opensciencegrid.org/LUXSim
mv latest ${RevNum}
cd ${RevNum}
make

# If this is the latest ( HEAD ) version in the repo, then create a symlink to HEAD
cd /cvmfs/lz.opensciencegrid.org/LUXSim
ln -s ${RevNum} HEAD

 

Build CLHEP

# Only login0[1-6].hep.wisc.edu are accessible from outside networks
ssh login06.hep.wisc.edu

# From login06, login to osggrid01.hep.wisc.edu (this is the cvmfs writer)
ssh osggrid01.hep.wisc.edu

# Make sure your path is set to these
export 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
wget http://proj-clhep.web.cern.ch/proj-clhep/DISTRIBUTION/tarFiles/clhep-2.2.0.4.tgz .
tar xvzf clhep-2.2.0.4.tgz 
mkdir -p clhep_build
cd clhep_build

# Create CVMFS install area where libraries and binaries will be installed
mkdir -p /cvmfs/lz.opensciencegrid.org/CLHEP/2.2.0.4

# Options with cmake
cmake -DCMAKE_INSTALL_PREFIX=/cvmfs/lz.opensciencegrid.org/CLHEP/2.2.0.4 ../2.2.0.4/CLHEP
make -j8
make test
make install
# At this point you should see all the libraries in /cvmfs
 

Build Geant4

# Only login0[1-6].hep.wisc.edu are accessible from outside networks
ssh login06.hep.wisc.edu

# From login06, login to osggrid01.hep.wisc.edu (this is the cvmfs writer)
ssh osggrid01.hep.wisc.edu

# Make sure your path is set to these
export 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

tar xvzf geant4.10.02.b01.tar.gz
