Summary

Action OASIS coupling interface between TOP and NEMO
PI(S) E. Maisonnave
Digest We propose to shape the existing ocean/sea-ice interface to an ocean/biogeochemistry coupling, to make possible the computing of TOP/Pisces equations (Aumont et al. 2015) in a separate executable and its coupling to the rest of the NEMO model. This modularity is supposed to enhance the overall computing performances by allowing (i) to reduce the TOP/Pisces module horizontal resolution and (ii) to choose the best suited parallel decomposition for both components. Regardless to result modifications that have to be evaluated, computation of the two modules can be performed concurrently, reducing time to solution even more. The OASIS coupling library (Craig at al., 2017), basis of the existing ocean/sea-ice interface, will ensure the efficient (parallel) communication of 3D fields, the easy switch between sequential and concurrent modes and, possibly, the coupling field interpolation.

Tests

Error: Failed to load processor box
No macro or processor named 'box' found
  • Test case name: CPL_ORCA2_PISCES
  • Test case functionality: The test must ensure that ocean and BGC can be compiled seperately, linked with OASIS and can run concurrently
  • Test case setup : Based on ORCA2 grid, need OASIS
  • Test case verification value: Correct SST after a one month long simulation
  • Status of the test case as for now : not defined yet. Status of the official ocean-BGC interface must be clarified first
