N96 on GA3 on Monsoon

Reported by: simon.tett Owned by: um_support
Priority: high Component: UM Model
Keywords: Cc:
Platform: MONSooN UM Version: 7.8

Description

Hi,

how many node hours/simulated year does GA3 at version 7.8 need on MOONSooN? I think on ARCHER it needs about 50 (6 nodes and about 8 hours per year).

Would nudging make any difference to this cost?

We don't support UM 7.8 on MONSooN. But MONSooN and ARCHER perform quite similarly - it's probably good enough for "cost" estimates to assume they perform equally core for core (note a MONSooN node has 32 cores cf 24 for ARCHER).

We don't have much experience with nudging - I have enquired with the Leeds group as a first step.

Hi Grenville

Thanks. Trying to run parallel to Buwen who is running GA3 at 7.8. Is there a GA3 at another version on Monsoon you support?

Things appear to have moved on - I only see GA3 at 7.7 and 7.8, GA4 would be supported.
