| 1 | This version is the master branch of the OASIS3-MCT climate coupler. It will contain the future developments for OASIS3-MCT_5.0 |
|---|
| 2 | |
|---|
| 3 | Since the first developments of OASIS3-MCT, it includes: |
|---|
| 4 | - A first beta version of Python API available (STFC) |
|---|
| 5 | - Add ability to set north and south thresholds on the SCRIPR CONSERV namcouple line. |
|---|
| 6 | - Add number of neighbors to the mapping filename for DISTWGT and GAUSWGT mapping files |
|---|
| 7 | - A « True » area normalisation in conservative remapping |
|---|
| 8 | - An addition of âadditional nearest-neighbourâ option in SCRIP CONSERV/DESTAREA (DESTNNEI, DESTNNTR) |
|---|
| 9 | - The possibility to deactivate the âadditional nearest-neighbourâ option (BILINEARNF, BICUBICNF, DISTWGTNF, and GAUSWGTNF) |
|---|
| 10 | - A bugfix for local distance calculation in DISTWGT and GAUSWGT interpolation |
|---|
| 11 | - More systematic test of NetCDF returned error code |
|---|
| 12 | - Fractional masks for the global conservation operation CONSERV (ESiWACE2) |
|---|
| 13 | - New options in global CONSERV to conserve fields with positive and negative values with average value close to zero (ESiWACE2) |
|---|
| 14 | - An hybrid MPI+OpenMP parallelisation of the SCRIP library (previously fully sequential) leading to great reduction in the offline calculation |
|---|
| 15 | - A new communication method, using the remapping weights to define the intermediate mapping decomposition, offering a significant gain at run |
|---|
| 16 | - New methods introduced in the global CONSERV operation reducing its costs by one order of magnitude while still ensuring an appropriate level |
|---|
| 17 | - Support for bundle coupling fields; |
|---|
| 18 | - Automatic coupling restart writing; |
|---|
| 19 | - Memory and performance upgrades; |
|---|
| 20 | - A new LUCIA tool for load balancing analysis; |
|---|
| 21 | - New memory tracking tool (gilt); |
|---|
| 22 | - Improved error checking and error messages; |
|---|
| 23 | - Expanded test cases and testing automation; |
|---|
| 24 | - Testing at high resolution (> 1M gridpoints), high processor counts (32k pes), and with large variable counts (> 1k coupling fields); |
|---|
| 25 | - Bicubic and Second Order Conservative interpolations (with the gradients of the fields being provided by the models); |
|---|
| 26 | - Exchange of data on only a subdomain of the global grid; |
|---|
| 27 | - The specification of how time statistics are written out (variable TIMER_Debug) in the configuration file ânamcoupleâ; |
|---|
| 28 | - Abilty to normalize the conservative remapping weights by the true areas of the grid using gridcell fraction |
|---|
| 29 | - New CONSERV options to normalize postive and negative values separately |
