Building MaCh3 DUNE

Dependencies

gcc (tested on 12.2.0)
CMake (tested on 3.27.7)
ROOT (tested on 6.28.06)

A setup script which pulls cvmfs dependancies is included here:

source setup_dune_env.sh

Cloning and Building

mkdir MaCh3_DUNE
git clone git@github.com:DUNE/MaCh3_DUNE.git MaCh3_DUNE
cd MaCh3_DUNE
mkdir build;
cd build

Then perform the cmake build command:

cmake .. -DCUDAProb3_ENABLED=[ON,OFF] -DCUDAProb3Linear_ENABLED=[ON,OFF] -DMaCh3_CORE_BRANCH="v1.4.8" -DBuild_NDGAr=[OFF|ON] -DDUNE_ANAOBJ_BRANCH="v03_06_00"

make install

Additional cmake options are available in the MaCh3-Core README

CUDAProb3 should be used as the default for atmospheric neutrino oscillations
CUDAProb3Linear should be used as the default for beam oscillations

Then source the installation of MaCh3:

source build/bin/setup.MaCh3DUNE.sh

This sets everything needed, and needs to be re-sourced on each terminal session when using MaCh3 (Along with any dependancies)

Event Rates

Once you've got setup you'll then need to setup some symlinks to point to your MC and spline files. You can do this by modifying scripts/link_files.sh script. You'll need to change the FILESDIR variable to point to the relevant folder on your machine. The places these files currently live are listed here:

Imperial College London lx:

/vols/dune/ljw20/

FNAL cluster:

/exp/dune/data/users/lwarsame

ComputeCanada Cedar:

/project/rpp-nilic/MaCh3_inputs

NERSC Perlmutter:

CVMFS:

Current (Feburary 2024) FD event rates using DUNE FD TDR inputs are below (ND is still under-development). These are made using xsec systematics at their prior central value. Oscillation parameter values used here are:
