Job Accounting (Allocations)

The TACC accounting system is based on node-hours: one unadjusted Service Unit (SU) represents a single compute node used for one hour (a node-hour). It then will be multiplied by a charge rate that reflects the "supply and demand" for the type of node you use.  For any given job, the total SU cost is:

SUs billed (node-hours) = (# nodes) x (job duration in wall clock hours) x (charge rate per node-hour)

The system charges only for the resources you actually use, not those you request.

Principal Investigators can monitor allocation usage via the TACC User Portal under "Allocations->Projects and Allocations". Be aware that the figures shown on the portal may lag somewhat behind the most recent actual usage.
