I am in the process of completing a Technical Assessment form for ARCHER2 usage on a (non-NERC) grant proposal.
For this, I require information on how well the UM scales on ARCHER2.
The jobs I am proposing are high resolution regional simulations.
Specifically, I need to provide a table showing how the runtime of my most computationally expensive job (I suppose the forecast jobs for my highest resolution nest) varies with the number of nodes used.
I don’t suppose you have any relevant data at hand (beyond what is available here http://cms.ncas.ac.uk/wiki/Archer2#Performance)?
For what it’s worth, my high resolution jobs will be 4-km grid spacing, 70 vertical levels, 100-second timestep,
