Installing CESM2 on MONSooN

Description

HI,

we have got CESM2 at 2x2 resolution partially installed on our local cluster in Edinburgh with the aim of using it for relatively short atmosphere only experiments. We think we would like to do experiments with CESM at this resolution and higher and for longer timescales too. To do this we would need super-computer time…

So a couple of questions:
1) Would it be possible for us to install CESM2 on Monsoon (or Archer2)
2) Would there be some compute resource available to test CESM2 and carry out some simulations. I'd guess on the order of 0.5-1 Million core-hours.

Hi Simon

1) Would it be possible for us to install CESM2 on Monsoon (or Archer2)

On Monsoon, you will need a MO partner, but otherwise, I see no problem.
On NEXCS you can install it but NEXCS will be discontinued at the end of Jan 2021.
On ARCHER2 - I'm sure you can (the CSE team may assist)

2) Would there be some compute resource available to test CESM2 and carry out some simulations. I'd guess on the order of 0.5-1 Million core-hours.

1 Million core-hrs is 15MAU which is borderline below the radar - better to apply for resource through the usual channels - I thought there already was a group in Edinburgh running CESM?

Hi Grenville,

Thanks for your response and hope your summer is going well.

By MonsoonI think I mean monsoon2 = NEXCS??? If monsoon2 is going what replaces it?

Massimo has been running CESM — this is an "upgrade" to CESM2. But do you know when Archer2 will be live? COVID seems to have delayed it. But sounds like we should apply in the normal way for resources for this then.

Monsoon2 will remain, but NEXCS (the NERC partition of the XCS) will end. NEXCS users will need migrate to ARCHER2.

We think ARCHER2 will be available before the end the year. Please do apply for resource in the normal way.

NERC (and I) shall announce the future of NEXCS soon.
