Simulation and reconstruction framework for the Light Dark Matter eXperiment.

Quick Start

• Install the docker engine
• (on Linux systems) Manage docker as non-root user
• Clone the repo: git clone --recursive git@github.com:LDMX-Software/ldmx-sw.git
  • Note: You need to setup an SSH-key with your GitHub account on the computer you are using.
• Setup the environment (in bash): source ldmx-sw/scripts/ldmx-env.sh
  • Note: If you are working with ldmx-sw at SLAC's SDF, you will need to set the TMPDIR environment variable so that program running the container has more than ~5GB of space to write intermediate files. The default temporary space (/tmp) is often full of other files already. A decent replacement is TMPDIR=${SCRATCH} which gives the program plenty of room for the files it needs to manipulate.
• Make a build directory: cd ldmx-sw; mkdir build; cd build;
• Configure the build: ldmx cmake ..
• Build and Install: ldmx make install -j2
• Now you can run any processor in ldmx-sw through ldmx fire myconfig.py

Documentation

The full documentation for ldmx-sw is available on github pages. A brief description of common commands is given below.

Common Commands inside Container

Command	Purpose
ldmx cmake ..	Configure the ldmx-sw build
ldmx make	Compile/build ldmx-sw
ldmx make install	Install ldmx-sw
ldmx fire config.py	Use ldmx-sw application and processors with input python configuration
ldmx python3 analysis.py	Run python-based analysis
ldmx ./bin/mg5_aMC	Run MadGraph5 inside (ubuntu-based) container

Other Container Configuration Commands

The environment script defines several other shell commands to help configure and debug the container environment.

• ldmx list repo : List the container tags that you could use with the input repository: dev, pro, or local
• ldmx use repo tag : Setup the environment for the container 'ldmx/repo:tag' and pull down the newest version if the repo is remote
• ldmx config : Print out how the container environment is currently configured
• ldmx clean all : Reset environment to a blank state

Use ldmx help for a full listing of these commands. If we don't define a command outside of the container, then the command is given to the container to run inside the current directory.
