Archer2 Technical Assessment Form

This is essentially the same request as this (MetUM performance, ARCHER2) but the links in the replies to that request no longer exist.

Just wondering if you have any tables of performance of the UM vs nodes/cores which is needed for an archer2 application. I’ve put something together for runs on Monsoon but I’m not sure if it’s exactly what they want as I’m changing resolution as well as number of nodes.

Thanks,

Leo

Are you applying for time on ARCHER for a NERC grant?

Hi Grenville,

No, it’s through EPSRC. It’s for the National Fellowships in Fluid Dynamics.

ARCHR2 performance data is available at: Performance of Standard UM Configurations

We’ve not done any scaling profiling on ARCHER2.

Old ARCHER scaling plots are at:
https://pumatest.nerc.ac.uk/trac/cms_website/wiki/UM/Configurations/Performance

This old site will disappear soon-ish.

That looks good, thanks. The N1280 is a good example for what I want to run so that should work.
