Release 3.0

[arporter]

As discussed, we need to make a 3.0 release. Mainly to facilitate the new users of the 'code transformation' functionality and to emphasise that the API has changed since the 2.5.0 release.

• (Closes #320) nonstandard stop fparser#451
• 448 make public example fparser#450
• Loop fusing and openmp transformations generating incorrect code #2701
• FFSL support is required (FFSL transport in LFRic depends on a kernel that loops over halo cells #2661)
• Document the OpenMP offload functionality (under https://psyclone.readthedocs.io/en/latest/transformations.html#openmp) and add/extend an LFRic example to show it.
• Update LFRic transformation signature? #2739
• [LFRic] [PSyAD] Function space pointers declared and assigned in random orders in generated adjoint test #2742 (PSyAD test-harness reproducibility)
• [LFRic] [PSyAD] PSyAD no longer computes adjoint of vector assigments properly in PSyclone 3.0-dev #2755
• (towards #2671) Parallel array privatisation #2697 Would be nice to have as it also fixes NEMO integration tests.
• Update version in Spack (and update Wiki to remind us to do this).
• [LFRic] Change index order for LFRic operators #2766 Change index order for LFRic operators.
• (Closes #2774) Refactor matmul2code to allow for more permutations of full ranges #2795 Allow Fortran matmuls to take matrices with non-contiguous ranges.

We want this before SC24.

• 2690 value verification #2694
• Loop Fusion Transform can create incorrect code #257

I might also consider #2483, that might be useful for work with the UM, but I need to check where this PR is exactly at

[DrTVockerodtMO]

• (Closes 2311) Add functionality to derive module and subroutine names of adjoint test from filename for LFRic API #2749

This task is almost complete so I have added it to the list.

@arporter Should we rename the "nemo" tutorials to Code transformation before this release as well?

Ideally, yes.

Ideally, yes.

I'll see if I can do this then

#2759 (which I assume should go into 3.0 as well) addresses a similar issue with library files. And there are the examples as well.

We should agree on a name - maybe just transformation? Or no_psykal?

[sergisiso]

For the folder names: generic or std_fortran are other options.

[arporter]

Thanks @LonelyCat124 and @hiker. I like "generic" but am happy to go with the consensus.

[LonelyCat124]

I had a chat with Sergi about the tutorials and we decided to leave that until we have time to redo them entirely, as they're very out of date.

[arporter]

OK.

[hiker]

generic sounds fine to me

• Update dl_esm_inf in PSyclone #2790 (which is useful for training) (should I perhaps move this up into the top level comment?)

[arporter]

We now have a hard deadline of 13th of December for this release. We should probably aim for at least a week earlier to allow for any unforeseen problems.

@arporter, it's Friday 13th of December for LFRic release to use PSyclone 3.0, which means we need to ideally be ready a week before that :)

[arporter]

The only thing outstanding now is #2701 (plus my small PR to update the OMP docs). Do you want to back-port your fix for this @sergisiso or shall we leave it?
@TeranIvy has the new, 'user-supplied kernels with operates-on dof' functionality been tested do you know?
We have CIUK from Weds to Fri next week so I would prefer to make the release on Monday or Tuesday if possible.

[arporter]

Release has been published on github and manually uploaded to pypi.
RTD has updated.
I've opened a PR on spack (https://github.com/spack/spack/pull/47964/files).
I'll email the LFRic list now!
