I have added Tim to CC in the event he has more to say on this subject.

This was done to accommodate changes for HPE Shasta. The existing pm_counters interface is the best source for energy-accounting data at present, and the "cray_aries" plugin already supports this format. For this reason we've renamed the acct_gather_energy/cray_aries plugin to acct_gather_energy/pm_counters going forward with Slurm 20.11.

Hi Jason,

Oh that's awesome, so we could potentially enable this now on our existing Shasta systems?

Thanks!
Chris
