Instructions for running Experiment 1 |
|
|
===================================== |
|
|
|
|
|
This is a 1-cpu, 10-hour integration used to make sure that all |
|
|
the files are available and that the sea-ice model compiles and |
|
|
runs. The reading of atmospheric forcing files and the computation |
|
|
of open-water bulk fluxes are carried out within pkg/seaice. |
|
|
|
|
|

Instructions for running Experiment 2 |
|
|
===================================== |
|
|
|
|
|
This is a 1-cpu test of the LSR solver. The solution is |
|
|
compared to that of experiment 1, which used the ADI solver. |
|

|
|
|
To run Experiment 2: |

|

|

Instructions for running Experiment 3 |
|
|
===================================== |
|
|
|
|
|
This is a test of periodic boundary conditions for LSR |
|
|
and ADI solvers. The domain has a flat bottom and |
|
|
is periodic both in the x and the y directions. |
|
|
All forcing files are null or constant (u10m = v10m = 5 m/s). |
|
|
|
|
|
To run Experiment 3: |
|
|
cd ../../../verification/lab_sea/input |
|
|
ln -sf DATA.1hour data |
|
|
ln -sf DATA.SEAICE.testadi data.seaice |
|
|
mitgcmuv_1 >&! output.txt |
|
|
mkdir exp3a |
|
|
mv *tave.0000000001.data exp3a |
|
|
ln -sf DATA.SEAICE.testlsr data.seaice |
|
|
mitgcmuv_1 >&! output.txt |
|
|
mkdir exp3b |
|
|
mv *tave.0000000001.data exp3b |
|
|
|
|
|
Use matlab script lookat_exp3.m to compare |
|
|
the output of exp2 to that of exp1: |
|
|
cd ../../../verification/lab_sea/matlab |
|
|
matlab |
|
|
lookat_exp3 |
|
|
|
|
|
If the dynamic ice solvers are correct, they should converge to a |
|
|
constant solution. The tests above show that both the ADI and the LSR |
|
|
solver are unable to handle periodic domains and therefore that they |
|
|
cannot be "correctly" parallelized. |
|
|
|
|
|
|
|
|
Instructions for running Experiment 4 |
|
|
===================================== |
|
|
|
|
|
This is a 2-cpu, 10-hour integration used to test |
|
|
tile edges for sea-ice dynamic solvers. |
|
|
|
|
|
To run Experiment 4: |
|
|
cd ../../../verification/lab_sea/input |
|
|
ln -sf DATA.10hours data |
|
|
ln -sf DATA.SEAICE.adi data.seaice |
|
|
mpirun -np 2 mitgcmuv_2x1 |
|
|
mkdir exp4 |
|
|
mv *tave.0000000010.data exp4 |
|
|
|
|
|
Use the matlab script lookat_exp4.m to compare |
|
|
the 2-cpu output to that of exp1: |
|
|
cd ../../../verification/lab_sea/matlab |
|
|
matlab |
|
|
lookat_exp4 |
|
79 |
|
|
80 |
The inaccuracy at the tile boundary can be decreased by increasing |
Instructions for generating and running a 2-CPU experiment on kalpana |
81 |
NPSEUDO in data.seaice at the expense of computation time. |
===================================================================== |
|
Also as sea-ice ages (thickens) the difference at the tiles becomes |
|
|
increasingly small. For solver pkg/seaice/adi.F a value of NPSEUDO=10 |
|
|
appears adequate for forward integrations but cannot be used for sea-ice |
|
|
adjoint model. Work is underway to fix this problem. |
