  • The Alliance includes prepend_path statement guarded by an existence check so users can more easily put module files in their own home directory without having to put module files for compiler/MPI in place that use inherit()
  • top of module hierarchy can also be determine via myFileName() and creatively using .match
    • see https://github.com/TACC/Lmod/blob/main/bugReport/my_modules/Core/gcc/10.0.lua
    • can be improved (less hardcoding) by also using myModuleName() and myModuleVersion() functions
