Description::
*Describe the configuration, who created it and who would find it useful*
The Met Office's official GA6 release for atmosphere-only N96 resolution at UM10.2, modified to run on
Raijin by ARCCSS CMS.
Based on the Met Office internal job GA:wiki:GAJobs/mi-ag338, modifications include:
* Cylc suite modified for Raijin's PBS queue
* Build settings changed to `nci-x86-ifort`
* Met Office internal paths changed to point to TIDS mirror
* Postprocessing task disabled (uses Met Office specific archive system)
More information about GA6 may be found on the Met Office trac: GA:wiki:GADocumentation/GA6.0
Run Instructions::
*Describe how to run the model at NCI*
On Accessdev:
[{
rosie checkout u-aa809
cd ~/roses/u-aa908
rose suite-run
```
Model will run for 20.5 model years, resubmitting every 1 model month

## Input Data
*Where are the input files used by the model, and are they accessible to all ACCESS users?*
Ancillary and initial condition data are sourced from TIDS, no local files are used
## Output Data
*Where does the model put its output, and how much does it generate?*
Data is in raijin:~/cylc-run/u-aa809/share/data/History_Data
* Dumps: 2.4 GB every 10 model days
* Processed: 4 GB per model month
* PA 1 GB
* PB 80 MB
* PC 500 MB
* PD 500 MB
* PE 700 MB
* PF 50 MB
* PG 150 MB
* PH 10 MB
* PI 1 MB
* PJ 40 MB
* PK 60 MB
* PM 800 MB
* Seasonal: 2 GB per model month
## Instructions for Testing
*How should this model be modified for testing? Tests should require minimal resources but still show the model's full behaviour - e.g. how do you reduce the run length to 2 cycles*
Set the value of `RUN_LENGTH` in file `rose_suite.conf` to `P2M` to run for two Cylc cycles (in the GUI go to 'suite conf' => 'Initialisation and Cycling' : 'Total Run Length')
## Performance
*How does the model perform on the NCI systems? Units should be modified as appropriate, e.g. per model hour for NWP runs*
|# NCPUs|# E-W|# N-S|# Walltime per Model Month|# SU per Model Month|# Memory|# Notes|
