Dear Ros and Grenville,
I am a Lecturer at UEA and am currently in the process of writing an ERC grant application. For this purpose, I require a cost estimate for supercomputing on the ARCHER2 system using UK Met Office climate models. I was wondering if you could help me check my current estimates in case that I overlooked anything major?
I believe the costs per CU would be £0.39 for an ERC grant on ARCHER2 and the CMS website here implies that UKESM1 demands around 165.7 kAU per model year. Graphs on the same website appear to imply that HadGEM3-GC3.1-LL would require only marginally smaller computing costs of maybe 140 kAU/model year. Is this correct? I would have expected a greater discrepancy.
So, assuming £0.39/CU, the cost for UKESM would be £28.59 per model year and £24.26 for GC3?
Would be great to receive your input,
