Typical resource requirements on raijin are:
Model | Grid spacing | Domain | Baroclinic timestep (s) | MOM cores | CICE cores | Walltime (hr/yr) | CPU (hr/yr) | Memory (Gb) |
---|---|---|---|---|---|---|---|---|
ACCESS-OM2 | 1° | 360 × 300 × 50 | 5400 | 216 | 24 | 0.38 | 118 | 83 |
ACCESS-OM2-025 | 0.25° | 1440 × 1080 × 50 | 1350-1800 | 1455 | 361 | 2.6 | 4,700 | 522 |
ACCESS-OM2-01 | 0.1° | 3600 × 2700 × 75 | 540 | 4358 | 799 | 10.4 | 68,000 | 2437 |
Scaling and performance are discussed in sec 3 of Kiss et al. 2019; the corresponding plot scripts and data are here. Note that the current 0.1 degree configuration (in table above) requires about half the walltime and CPU hours of the configuration in table 2 of the paper.
Details of run performance are given in .csv tables auto-generated by https://github.com/aekiss/run_summary in /g/data/hh5/tmp/cosima/access-om2-run-summaries
on NCI. Some analysis plots using this data are here.
