Notes

The GPU event energy meter captures the energy used by the GPU between PetscLogGpuEnergyMeterBegin() and PetscLogGpuEnergyMeterEnd().

PetscLogGpuEnergyMeterBegin() and PetscLogGpuEnergyMeterEnd() collect the energy readings using nvmlDeviceGetTotalEnergyConsumption(). The function cupmStreamSynchronize() is called before the energy query to ensure completion.
