Since its first official release in November 2004, the development and
improvement of the OASIS4 coupler went on. Active user support was also
provided to the few groups that started using OASIS4. The tasks
realised
are the following:
- Bug fixes, optimisation, and validation of bilinear and trilinear
interpolation (masked point treatment, missing values, etc.).
- Support and validation of 2D bicubic interpolation (16-point and
gradient methods).
- Partial support of Reduced Gaussian grids:
- all available types of interpolation for fields going onto
Gaussian reduced grid;
- nearest neighbour interpolation of fields coming from a
Gaussian reduced grid;
- direct transfer of fields between two components working on
identical (Reduced Gaussian) grids where no interpolation is needed.
- Bug fix for remapping/interpolation search for cyclic source
grids.
- Support of non-gridded data (not fully validated yet).
- Support for components which include processes that do not have
any grid defined.
- Support and validation of applications running more than one
component concurrently.
- Strict use of MPI1.2 standard when option PSMILE_WITH_MPI1 is
activated.
- Support of I/O parallel mode using PARallel NetCDF.
- Revised PMIOD and SMIOC XML file structure in agreement with GUI
and WSS working group.
- Testing and various debugging using toy coupled models.
- Adaptation of OASIS4 sources to PRISM Standard Compiling
Environment (not released yet).
- Use of pdflatex for documentation.
- Active support for the GEMS project, via e-mails.
- Active support for SMHI (coupling of SMHI regional Arctic
models), via e-mail and visit of R. Redler to SMHI.
- Active support for IFM-GEOMAR (Kiel) (using OASIS4 with
pseudo-models to interpolate high-resolution fields).
- Active support for UK MetOffice via e-mail.
- Presentation at the EGU meeting 2005.
