Spack Package for MET

[rbeucher]

I need to install METPlus which is a wrapper on MET. MET needs to be installed on NCI Gadi and I was wondering if someone could have a look at that.

See ACCESS-NRI/METPlus-workflow#1

Thanks!

@harshula would you have time to get me through a SPACK crash course so I can see how much work is needed there?

After a discussion with @aidanheerdegen, I think having someone from MED pair up with someone from the release team on this would be good. @max-anu ?

Here is the link to the MET documentation. METPlus is the python wrapper that we will use to call MET.

Had a chat about this last week. Looks like the dependencies are already in Spack. If the METPlus build system is good, a simple SPD should be sufficient.

Thanks @harshula, Would be great if you could show @max-anu how it is done.

Hi @max-anu ,

• The quickest way to get a feel for Spack is to build access-om2. The instructions are: Develop Spack build infrastructure ACCESS-OM2#6 (comment)
• Then, have a look at the spack_packages git repository that was cloned in the aforementioned instructions. In particular have a look at libaccessom2 and oasis3-mct. They represent two extremes of what needs to be done if the source tarball has a good vs bad build system.
• Make sure you understand the source tarball built system well before starting to work on the Spack Package Definition (SPD). AKA package.py.

We should also check this hasn't already been done by the Bureau. @ScottWales have you built METplus with spack already?

[ScottWales]

Yes, there's a recipe in the spack-environments repository, and a container available on Gadi - https://forum.access-hive.org.au/t/metplus-5-0-available-at-nci/810
