Bureau of Meteorology (Melbourne, Australia):
- 2D coupling between MOM4p1 and UN6.4 (limited area model set up for tropical cyclone Ului)
- 24 cores for MOM4p1 (resolution of 0.1 degrees horizontal), 160 cores for UM6.4 (0.11 degrees horizontal), 16 cores for OASIS4
- field exchange between each model at every time step
- Platform: SUN constellation with 576 nodes, each with 2 quad-core Intel 64-bit Xeon Nehalem procesors, total: 4808 CPU cores (more details).
Alfred Wegener Institute, (Bremerhaven, Germany):
- 2D ocean-atmosphere between FESOM and ECHAM5 (for now a regular grid is used in FESOM and the interpolation from the regular to the finite-element grid is done in FESOM, OASIS4 is used for the parallel repartitioning only)
- ECHAM5.4 runs on 6 PEs and the partitioning is 6 stripes of 60 deg.width and 180 deg length. FESOM runs on 8 PEs and the partitioning of FESOM is in 8 stripes of 22.5 deg length and 360 deg. width.
- OASIS4 runs on 2 PEs and performs the redistribution of data.
GEMS community (ECMWF, Meteo-France, and KNMI):
- 3D coupling between atmospheric dynamic (IFS) and atmospheric chemistry models (no vertical interpolation needed as the vertical levels of the source and target component match).
- Coupling fields on Gaussian Reduced, Gaussian, and non-geographical grids
- Global search needed
- Ocean-atmosphere 2D regional coupling (RCO-RCA)
- Data exchange occur through root process (no global search for now).
- Domains are centered at the pole; RCA domain is larger than RCO; climatology is used to fill the difference.
- Quasi-production runs (used for atmosphere parameter tests).
