ARCHIVED: Use a .modules file in your home directory to save your user environment on an IU research supercomputer

The Modules environment management system looks for a .modules file in your home directory whenever a new shell is opened. It will execute any module commands it finds there.

For example, if the Intel 13 and GCC 4.7 compilers are always wanted, but the Open MPI libraries might be either GNU or Intel, a typical .modules file might look like this:

  module load core
  module load gcc/4.7.2
  module load intel/13.0.1
  module load openmpi/intel/1.6.3
  # openmpi/gnu/1.6.3
  module load fftw/intel/3.3.3

Note that the # makes the entire line inactive.

To change between the modules, simply edit and source the file.
