The accounting currency on ECMWF supercomputer is the SBU (System Billing Unit) The accounting system is fully described here: https://software.ecmwf.int/wiki/display/UDOC/HPC+accounting Basically, " To ensure that computing resources are distributed equitably and to discourage irresponsible use users' jobs are charged " and SBU = P * (ELAPSED_TIME) where P = 50365140 / (3617 * 36 * 86400) is a fixed proportionality factor, adjusted so that the system will deliver 50365140 units per day on a "typical" ECMWF job mix on the ccb system (3617 * 36 is the number of physical CPUs of the cray system and 86400 the number of seconds in a day) ELAPSED_TIME is the elapsed time (real time in seconds) recorded for a job, multiplied by the number of physical CPUs used by the job Examples (copied from ECMWF User Documentation): A serial job using 1 hour (3600 seconds) of elapsed time will be charged about 16.11 SBU.
