IPSL ORCA1 configuration on ARCHER

Instructions for running the ShaCoNEMO ORCA1 setup on ARCHER.

Access

You need to register with the NEMO website to extract the code: http://www.nemo-ocean.eu/user/register

The ORCA1 configuration is held in the ShaCoNEMO repository. You need to register for access, but this uses the same username and password as main NEMO repository.

To create a branch to hold your code changes on the NEMO repository, you will need additional permissions.

References

The main NEMO website gives more general instructions on building & running NEMO with the standard confgurations included in the code: http://www.nemo-ocean.eu/Using-NEMO/User-Guides/Basics/NEMO-Quick-Start-Guide

ORCA1_LIM3_PISCES configuration is documented on the ShaCoNEMO (Shared Configuration) wiki: https://forge.ipsl.jussieu.fr/shaconemo/wiki/README_ORCA1_LIM3_PISCES

  • LIM3 is the sea-ice
  • PISCES is the biogeochemical model

NEMO uses an external library to handle model output diagnostics (XIOS), documented here: http://forge.ipsl.jussieu.fr/ioserver/wiki

Code versions

Here we have used the following versions, based on the NEMO/ShaCoNEMO pages:

  • XIOS-1.0 r703
  • NEMO_3.6_stable r6969
  • ShaCoNEMO r60
  • ORCA1 input data set v9

Note: Although XIOS-2.0 is now recommended, revision 932 which is suggested for ORCA1 gave a link-time error which was not investigated.

Code extract

On ARCHER, navigate to the directory that you wish to hold the code. You may wish to use the home directory as this is backed up.

To checkout to a directory called NEMOGCM_3.6_r6969, run the following, replacing mylogin with your NEMO username (you will be prompted for your password):

svn --username "mylogin" co -r6969 http://forge.ipsl.jussieu.fr/nemo/svn/branches/2015/nemo_v3_6_STABLE/NEMOGCM NEMOGCM_3.6_r6969

This creates an subversion "working copy". Running svn info lists the revision that was checked out, and svn diff lists the changes that have been made.

Then setup and extract the ORCA1 configuration:

cd NEMOGCM_3.6_r6969/CONFIG

Then edit cfg.txt to add the line:

ORCA1_LIM3_PISCES OPA_SRC LIM_SRC_3 NST_SRC TOP_SRC

Then checkout the ORCA1 configuration:

svn --username "mylogin" co http://forge.ipsl.jussieu.fr/shaconemo/svn/trunk/ORCA1_LIM3_PISCES

Use same username and password as main NEMO website.
