Topics:
- Fluent Ansys licenses on CC (number of licenses limitation?).
- Organizational issues and ideas.
Ansys Licenses
limited number of Ansys licenses makes it a potential issue to use them on CC
Used to not allow this on CC or parallel nodes but we have become lax in this
Going forward we will allow this even though it isn't efficient
Against intervening in license disputes, just let people run lmutils
if we take RCS purchased licenses and make them strictly TRES we could track them in SLURM but this would potentially introduce blocking/fragmentation issues
Just going to note potential license issues in the wiki and the use of lmutils to identify who is using them.
Tracking module usage to enable removal of clutter:
add to module files to write out jobids they were called in as well as the module name with touch to a file in the /global/software/var directory
create a file per job, have a cron job to roll them all up into a single DB every hour
need to update the whatis for the modules -what do we want this to be used for?
