Facility ÷ IT energy

The grid data is unavailable right now, so emissions and cost cannot be computed. Electricity still updates.

Method and defaults

IT power is accelerators × board power × server overhead × average load, and facility power multiplies it by PUE; energy, emissions and cost then follow from the job’s hours and the market’s hourly carbon intensity and day-ahead price. The best start is the hour in the next 48 hours, among those where the whole job fits, with the lowest mean carbon intensity. Defaults are 1.8× server overhead, PUE 1.56 and 70% average load; cost is the wholesale day-ahead component only, and board power excludes host CPUs, memory, networking and cooling.
