SBU = P * N * T |
where:
| P = 117602602 470410408 / (2000 8098 * 128 * 86400) | is a fixed proportionality factor, adjusted so that one cluster the entire Atos system will deliver 117470,602410,602 units 408 SBU per day on a "typical" |
| N | Is the number of (physical) cores allocated to a job. |
| T | is the elapsed time (real time in seconds) recorded for a job. |
...
- A serial job using 1 hour (3600 seconds) of elapsed time will be charged about 1918.14 91 SBU.
- A parallel job requesting 2 nodes, running for 3 hours elapsed time will be charged 1470014522.32 43 SBU.

To monitor your SBU usage on the Atos, which is currently not charged against SBU allocations, can be monitored with the Atos Preproduction HPC SBU Accounting portal Until 1 November 2022, the main HPC SBU accounting portal will only shows Cray HPCF usage. (Cray until 31 Oct 2002, Atos from 1 Nov 2022) charged against allocations please visit the HPC SBU accounting portal and login with your relevant computer user-ID. |
Any Atos usage before 1 Nov 2022 can be monitored at You may use the Atos Preproduction HPC SBU Accounting portal to keep track of your SBU utilisation on the Atos HPCF. You can login with your usual ECMWF credentials.
