Notes

• This machine is hungry; it has dynamic CPU frequency scaling disabled, so it is constantly at full power.

• The actual execution environment is also virtualized, which may add a slight overhead.

• This is a shared machine, so power consumption records are not always well-isolated from other workloads.
