Agenda

This meeting is for Q&A: there are no pre-planned general topics.

• Yang: multi-user scenario
  • Global shared directory with spack installation
  • Right now, all users are running the same spack instance
  • Does not use spack env (or Spack environments)
  • Encountered and issue with hdf5 install: sometimes it works and sometimes not
    • Peter: I'm not sure how this would result from sharing instances, can you create a clone of Spack in a new, non-shared directory and see if you can get the same hdf5 error?
    • The fact that it is occurring with hdf5 only seems to indicate more of a problem with hdf5 than with the method of use
• Prithvi: is there a way to add LmodMessage() to the module file lua script via spack recipe? So you can change the display output of module load but only for specific packages.
  • Can manually edit the output lua files
  • Peter: https://spack-tutorial.readthedocs.io/en/latest/tutorial_modules.html#working-with-templates
  • Prithvi: use case:
    • Using containers to install some packages
    • Creating binary caches from that
    • Creating package.py files, some of which create containers that install a package
    • Want the modules associated with installs using these containers to highlight that a container was used to install them (and is needed for running)
  • Peter: suggestion:
    • Each package.py file can define an environment variable
    • You can then modify the lua module template to check for this variable and print a message if it is encountered
