10. Increasing the resolution: BENGUELA_VHR¶
Now that you have successfully run the default configuration, you can try running another configuration: BENGUELA_VHR.
Create a new configuration directory for
BENGUELA_VHR
As for the previous configuration, edit the paths in
start.m
andcrocotools_param.m
(or copystart.m
andcrocotools_param.m
fromBENGUELA_LR
)Make the appropriate changes in
crocotools_param.m
to increase the resolution to 1/12°Re-run preprocessing for this new configuration (grid, bulk, forcing, bry, ini)
Make the appropriate changes in
cppdefs.h
(defineBENGUELA_VHR
,MPI
,BULK_FLUX
,FRC_BRY
, undefCLIMATOLOGY
), andparam.h
for running BENGUELA_VHR in parallel on 16 CPUsAs for the previous configuration, edit the paths in
jobcomp
(or copyjobcomp
fromBENGUELA_LR
). And re-compile the modelMake the appropriate changes in
croco.in
: change the time step!As in the previous configuration, copy the batch job:
cp ~/croco/croco/SCRIPTS/example_job_croco_mpi.pbs .
Edit it (notably change the number of CPUs used), and run the model:
qsub example_job_croco_mpi.pbs
Test questions:
On how much CPUs could you run the model (max # of CPUs)?
