Recommendation

Switch over to hierarchical names on all platforms.

1. Create a customization file for new names, but leave it empty. Use the command:

   touch ~/.modules-carbon-2
   

2. Edit your .bashrc file and update your module selection.
   • For module names of the form name/version, remove the version numbers. This will yield the current default version.
   • Run the command module avail name, and append to the names you use the MPI, compiler and versions as needed.
   • If you get errors of the form… ERROR:151: Module 'troubled_name' depends on one of the module(s) 'other_name1 other_name2' …, add module load … commands for the needed module(s) other_names before loading "troubled_name".
