Testing LArSoft at CERN Neutrino Cluster

Setting up and running LArSoft at Neutrino Computing Cluster

Detailed explanations on how to install/use LArSoft can be found in the LArSoft wiki pages:

Setting up your enviroment

For each experiment (DUNE, MicroBooNE, SBND, LArIAT...), you need to build the experiment-specific code. Below is an example of how to set up the code for CERN Neutrino Cluster. A very similar workflow can be expected for other experiments code, but different packages and versions are required.

• Set up the UPS for dunetpc
  • source /cvmfs/dune.opensciencegrid.org/products/dune/setup_dune.sh

• Setup the UPS for LArSoft
  • source /cvmfs/larsoft.opensciencegrid.org/products/setup

• Setup your working space by making a directory
  • mkdir dunetpc
  • cd dunetpc

• Now set up the basic tools and variables that are needed
  • setup mrb
  • export MRB_PROJECT=larsoft

• At this point, we need to make a directory for this larsoft release (release version called XX_YY_ZZ here, replace with the version you want)
  • mkdir larsoft_vXX_YY_ZZ
  • cd larsoft_vXX_YY_ZZ

• Create a new installation of LArSoft (building development area) specifying version and qualifiers
  • mrb newDev -v vXX_YY_ZZ -q e9:prof

• IMPORTANT the step above generates a setup that you must type (now and whenever you log in):
  • souce localProducts_larsoft_vXX_YY_ZZ_e9_prof/setup

• You will now see a directory called srcs (sources - where the code is kept). Move to this directory and check out the code packages you want
  • cd srcs/
  • mrb g dunetpc

• Build your release and tell LArSoft to use your locally built libraries:
  • cd dunetpc/
  • mrbsetenv
  • mrb i -j4
  • cd ..
  • mrbslp

Setting up older versions

• Set up the UPS for dunetpc
  • source /cvmfs/dune.opensciencegrid.org/products/dune/setup_dune.sh

• Setup the UPS for LArSoft
  • source /cvmfs/fermilab.opensciencegrid.org/products/larsoft/setups

• Setup your working space by making a directory
  • mkdir dunetpc
  • cd dunetpc

• Now set up the basic tools and variables that are needed
  • setup mrb
  • export MRB_PROJECT=larsoft

• At this point, we need to make a directory for this LArSoft release (release version called XX_YY_ZZ here, replace with the version you want)
  • mkdir larsoft_vXX_YY_ZZ
  • cd larsoft_vXX_YY_ZZ
  • See the release page for a description of the different releases.

• Create a new installation of LArSoft (building development area) specifying version and qualifiers
  • mrb newDev -v vXX_YY_ZZ -q e9:prof

• IMPORTANT the step above generates a setup that you must type (now and whenever you log in):
  • souce localProducts_larsoft_vXX_YY_ZZ_e9_prof/setup

• You will now see a directory called srcs (sources - where the code is kept). Move to this directory and check out the code packages you want
  • cd srcs/
  • mrb g -t vXX_YY_ZZ dunetpc

• Build your release and tell larsoft to use your locally built libraries:
  • cd dunetpc/
  • mrbsetenv
  • mrb i -j4
  • cd ..
  • mrbslp

Checking available versions

After you have run the two scripts that are reported above, you can run

• ups list -aK+ dunetpc or
• ups list -aK+ larsoft

in order to see the available versions of dunetpc or LArSoft
