Access-om2 ksu benchmarks

Hi,
I was wondering if someone could please point me to the computational cost benchmarks for:

  • ACCESS-OM2-025
  • ACCESS-OM2-01

I.e. How many KSU for 1 month simulation (or other standard period) in each case, and how many CPUs for the layout.
Thanks,
Dave

ACCESS-NRI haven’t created new benchmarks - @aekiss is best placed to answer this :slight_smile:

The numbers we usually put in our NCMAS applications are as follows:

Model Resolution Processors Memory Cost
ACCESS-OM2-025 0.25°,
50 levels		 1824 36 Gb/node 7.2 kSU/yr
ACCESS-OM2-025-BGC 0.25°,
50 levels		 1824 124 Gb/node 13.1 kSU/yr
ACCESS-OM2-01 (small) 0.1°,
75 levels		 5088 34 Gb/node 123 kSU/yr
ACCESS-OM2-01-BGC (small) 0.1°,
75 levels		 5088 63 Gb/node 245 kSU/yr
ACCESS-OM2-01 (large) 0.1°,
75 levels		 12144 35 Gb/node 156 kSU/yr

But it varies a lot depending on amount of diagnostics being saved or additional tracers etc.
