EnergyOpt

[jbakosi]

Hi folks,

Is EnergyOpt available in a latest release and/or main? I tried grepping for 'energyopt' but get no hits. If so, is it enabled differently?

Also, if available, do I need some non-user permissions on a HPC machine to be able to use DVFS?

Thanks,
J

The energy optimization code is in a branch bilge/energy_opt and hasn’t been updated for a while, we can look to update it to merge it into main. The feature can be enabled by using --enable-energyopt build option and it does require non-user privileges since the energy optimization code in charm++ runtime makes changes to CPU frequency using DVFS.

Thanks,
Kavitha

Thank you, Kavita,

I would like to try the energyopt functionality. If it is not much trouble, could you please merge it into main?

Thank you,
