Hello,

Would someone have the ACCESS-OM2-025 + WOMBAT performance and scaling on Gadi to be included in a NCMAS proposal please?

Thanks,
laurie

Hi @LaurieM

Here are the ACCESS-OM2-025-BGC (0.25°, 50 levels) performance figures from last year:
13.1 kSU/yr
6.7 yrs/day
1824 cores

There’s a scaling analysis for 0.25° in Kiss et al 2020 but that was on Raijin and without BGC. As far as I know nobody’s done a scaling study on Gadi with BGC at 0.25°. @paulleopardi did you do any tests at 0.25°?

HI @aekiss

I did my ACCESS-OM2 testing at 0.1 degrees with JRA55v13.
See The ACCESS-OM2 Performance Report, especially pages 26 to 29.

Revisiting this same question, has anyone done any scaling analysis of ACCESS-OM2-025 on gadi in the last year? It would be great to have scaling published alongside ACCESS-NRI model releases!

Update in case anyone else is wanting ACCESS-OM2-025 scaling for NCMAS, it sounds like @minghangli is going to look into this now. Thanks @minghangli!
