Implementation and tests
Previous implementation (2020 work plan)
See wiki:2020WP/ENHANCE-14_smueller_OSMOSIS_streamlining#Implementationandtests.
Continuation of implementation (2021 work plan)
source:/NEMO/branches/2021/dev_r14122_HPC-08_Mueller_OSMOSIS_streamlining@14829 has passed the standard SETTE tests.
Review
This change is self contained (to the zdfosm module) and passes SETTE tests. It is ready for merge. Mike Bell (and Andrew Coward)
Post-review updates (compatibility with nn_hls=2 and ln_tiling=.true. options)
Regression testing has been carried out using the standard WED025 SETTE test with the modification

to enable in the reference WED025 configuration both the OSMOSIS boundary-layer scheme (as included in the SETTE WED025 tests listed in the table above) and the OSMOSIS-specific extension of mixed-layer eddy-induced transport (not included in the SETTE WED025 tests listed in the table above), with respect to reference output generated using source:/NEMO/branches/2021/dev_r14122_HPC-08_Mueller_OSMOSIS_streamlining@14822 plus changeset [14858] (to enable compilability on the HPC system used for testing) with the addition of ln_mle=.true. in file cfgs/WED025/EXPREF/namelist_cfg (14822+).
