Thanks @imaranresearch. Well done for getting the diff back to a manageable size.
Mostly it's just a matter of tidying what you have.
I'll actually try running the integration test next time around.

Hi @imaranresearch, unfortunately, the new integration test failed:
https://github.com/stfc/PSyclone-mirror/actions/runs/18196318722/job/51803343216#step:16:38
It looks as though it's a simple matter of a path not quite matching what is expected - have a close look at the other NEMO jobs to see what's different.

@imaranresearch The run.stat divergence was due to using different keys in makenemo than the reference KGO. I pushed a fix for this plus some small changes to properly upload the results at the end of the workflow. Now all integration workflows are green.

Thanks very much @imaranresearch and @sergisiso. It's very nearly there now. I think there just one more bit of tidying to do in the script (see inline). Integration tests all work and absolute timings are shown in the MongoDB chart. @sergisiso I guess we need to add a baseline figure somewhere to get the relative slowdown plot to work for the new series? (We should have this documented somewhere really!)

Once you've done that Imaran, please could you set the label on the PR to 'ready for review' as that makes it easier for me to spot.
