OASIS4 coupled models

  • 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
  • SMHI
    • 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).
  • GENIE (not active anymore)
    • Global ocean-seaice-atmosphere 2D coupling (GOLDSTEIN ocean, IGCM atmosphere)
    • Coupling fields on reglonlat and non-geographic grids
    • Interpolative coupling between ocean (equal area 36x36 grid) and other models (T21 64x32 grid)
    • OASIS4 PSMILe code, SMIOCs and SCCs generated "automatically" from metadata describing GENIE model framework and grids, using BFG (Bespoke Framework Generator)
    • Different deployments of GENIE framework being tested (e.g. single/multiple executables)
