Issues for

The GitHub - coecms/oasis3-mct: Derivative version of OASIS3-MCT from CERFACS ( repository does not have issues enabled, so I am documenting two issues here.


The issues that I want raised are:

  1. The file util/make_dir/make.nci should be in the repository, not on the file system.
  2. The contents of /g/data/p66/pbd562/test/t47-hxw/jan20/4.0.2/oasis3-mct should be pushed back to the repository, either on the new_modules branch or on a new branch.

Doing so should simplify the building of ACCESS-ESM 1.5 as per GitHub - coecms/access-esm-build-gadi and its fork GitHub - penguian/access-esm-build-gadi: Fork to be used to migrate build to using GitHub repositories on the way to creating a Spack build of ACCESS-ESM 1.5.

Comments? Thoughts?


Martin Dix’s version of the UM source code at (sorry, private repository) produces a UM executable, that when used with the existing executables in access-esm/config.yaml at pre-industrial-MartinDix-um_hg3_exe · penguian/access-esm · GitHub

      exe: /g/data/access/payu/access-esm/bin/coe/mom5xx
      exe: /g/data/access/payu/access-esm/bin/coe/cicexx

reproduces the output produced by access-esm/config.yaml at pre-industrial · coecms/access-esm · GitHub

One of the key difference between the UM build in GitHub - penguian/access-esm-build-gadi: Fork to be used to migrate build to using GitHub repositories
and the UM build in is that the latter
uses the following script snippet in

export FPATH=${PBD_OASIS_DIR}/Linux/build/lib/psmile.MPI1/:${PBD_OASIS_DIR}/Linux/build/lib/mctdir/mct:${PBD_OASIS_DIR}/Linux/build/lib/scrip:$FPATH
export RPATH=${PBD_OASIS_DIR}/Linux/lib:$RPATH

This snippet is now in the branch GitHub - penguian/access-esm-build-gadi at build-um-from-MartinDix-patch

Looking at /g/data/p66/pbd562/test/t47-hxw/jan20/4.0.2/oasis3-mct we see:

Hi @paulleopardi. I didn’t even know we had a fork of oasis3-mct on our github org. It looks like it hasn’t been updated in a very long time. It’d probably be best to adapt the original repo at GitHub - COSIMA/oasis3-mct: Derivative version of OASIS3-MCT 2.0 from CERFACS ( for your purposes, as that has more recent development, including some contributions from you on Gadi porting.

Thanks. I have updated my own fork, and added a branch GitHub - penguian/oasis3-mct at new_modules_pbd562 that I have been using for testing. Testing of the GitHub - penguian/access-esm-build-gadi at build-all-using-oasis3-new-modules-pbd562 build that uses this branch has so far been successful when run with the GitHub - penguian/access-esm at pre-industrial-using-oasis3-new-modules-pbd562 branch. This bitwise reproduces the output of GitHub - coecms/access-esm at pre-industrial

Also, I have found the source of the access oasis3-mct/ompi.4.0.2 module
