How to ... Determine Account Charges

Computational and storage resources are allocated to repositories by DOE. Repositories are charged for computer usage by their members on the NERSC MPP machines and the analytics server DaVinci. The basic unit of charge is the MPP hour, equivalent to one hour of computing on one IBM POWER 3+ processor. Repositories are also charged for HPSS usage by their members.

Parallel jobs are charged for all processors on each node it uses.

A higher charging rate is available for those who need a faster turnaround time (but should be used with caution becaus this can deplete your project's allocation rapidly!) and a lower rate is available for those who can wait longer.

See the Usage Charging web page for more information.

Monitoring Usage

NERSC users monitor their usage using the NERSC Information Management system (NIM).
