1 wall-clock core-hour is defined as 1 processor core allocated for 1 hour of wall-clock time. Allocating a full node (16 cores Anselm, 24 cores Salomon)
for 1 hour amounts to 16 wall-clock core-hours (Anselm) or 24 wall-clock core-hours (Salomon).

In future, the factors F will be updated, as new systems are installed. Factors F are expected to only decrease in time.
