Modules

Most modules here just update your environment for a single, particular software package, by adding that package's directories to some runtime search path(s) like $PATH or $LD_LIBRARY_PATH or $PYTHONPATH. The modules below are a bit different:

• clas12
  • loads a bunch of other modules to provide a full CLAS12 environment in one shot
• tmpfs
  • gets various software, e.g., apptainer, to use a /tmp alternative, e.g., for when it's mounted noexec
  • Note, coatjava versions prior to 10.1.0 require this on el9 at JLab for SQLite support
• sim
  • initializes modulefiles from JLab's geant4 group, e.g. gemc
• scicomp
  • initializes modulefiles from JLab's scicomp group, e.g. cernlib/2023
• system
  • sets two convenience variables, used only by these modulefiles
    • OSRELEASE, based on the operating system and this script
    • CLAS12_HOME, the absolute path to this local repository
  • sets PATH, LD_LIBRARY_PATH, and PKG_CONFIG_PATH for some common C++ libraries, e.g.,
    • fmt
    • yaml-cpp
• util
  • both an environment module for clas12-utilities, and a directory containing some scripts used only during environment setup:
  • osrelease.py: just prints a string for OSRELEASE, determined by the operating system and compiler
  • functions.tcl: Tcl support procedures used in many clas12 modulefiles
  • siteconfig.tcl: unused, a modulefile configuration for registering Tcl procedures
  • .generic: tcl script to set $name and $version based on a modulefile's path, and then load its .common
  • env: bash environment file to switch to this clas12 modulefiles and generate symlinks to builds
