|
|
|
|
--------------------------------------------------------------- |
|
|
A) setup the experiments (incl. llc90 and cs32 core2.cnyf runs) |
|
|
--------------------------------------------------------------- |
|
|
|
|
|
0) get MITgcm as explained @ http://mitgcm.org/public/source_code.html |
|
|
1) the following assumes that you are in directory MITgcm/verification/ |
|
|
i.e., after checkout of the model repository, do: |
|
|
cd MITgcm/verification/ |
|
|
from here, get the MITgcm_contrib/gael/verification/setup_these_exps.csh |
|
|
c-shell setup script e.g. by typing |
|
|
cvs co MITgcm_contrib/gael/verification/setup_these_exps.csh |
|
|
mv MITgcm_contrib/gael/verification/setup_these_exps.csh . |
|
|
Unless you already had something in MITgcm_contrib you may want |
|
|
to remove that directory. Hereafter we wont need it anymore. |
|
|
2) execute the setup script by typing |
|
|
source ./setup_these_exps.csh |
|
|
A pre-requisite is that you are logged in to the MITgcm |
|
|
cvs server. If you completed step1, you indeed already are. |
|
|
If otherwise, see http://mitgcm.org/public/source_code.html |
|
|
3) step2 creates a directory global_oce_tmp_download that |
|
|
contains the experiments directories. Move them (incl. |
|
|
global_oce_input_fields) to MITgcm/verification and cd to |
|
|
that location. Once you have done this succesfully you may want |
|
|
to remove global_oce_tmp_download. We wont need it anymore. |
|
|
4) exectute MITgcm with testreport. Two examples from one machine. |
|
|
To run the cs32 test on one cpu : |
|
|
./testreport -t global_oce_cs32 |
|
|
And to run the llc90 test on 12 cpus, using mpi |
|
|
./testreport -match 6 -of=../tools/build_options/linux_amd64_gfortran -MPI 12 -command 'mpirun -np TR_NPROC ./mitgcmuv' -t global_oce_llc90 |
|
|
The optfile may be swaped for one that better suits your machine. |
|
|
5) for llc90 experiment testreport should show something like |
|
|
Y Y Y Y> 6<16 16 12 12 16 16 13 11 12 11 11 11 12 13 10 11 . . pass global_oce_llc90 |
|
|
Y Y Y N .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. . . N/O global_oce_llc90.core2 |
|
|
Y Y Y N .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. . . N/O global_oce_llc90.ecco_v4 |
|
|
Y Y Y N .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. . . N/O global_oce_llc90.ecmwf |
|
|
implying that the main experiment ran as expected in global_oce_llc90/run. In contrast |
|
|
the sub-experiments, by default, fail by omission of surface forcing fields. This |
|
|
omission saves disk space and download time. In case you want to run the sub-experiments, |
|
|
you will need to obtain additional inputs. Contact us about this if applies. |
|
|
|
|
|
----------------------------------------------------------------------- |
|
|
B) in case you want to change stuff on your end, or for troubleshooting |
|
|
----------------------------------------------------------------------- |
|
|
|
|
|
0) to run the core2, ecmwf, and ecco_v4 subexperiments you will need |
|
|
extra stuff in global_oce_input_fields. Contact us if need be. |
|
|
As a side note, for the verification experiment purpose, you |
|
|
do not want to link the large ecco data sets (RADS etc). |
|
|
|
|
|
1) In linking the experiments to one another we rely on 'build/genmake_local' and |
|
|
'input*/prepare_run' which may be worth a special mention, at least to new MITgcm users. |
|
|
|
|
|
1.1) most importantly : if you remove these files, the exps wont run or even compile. |
|
|
1.2) build/genmake_local specifies the use of xmakedepend (since the default |
|
|
cant handle so many files) and in global_oce_cs32 it points to |
|
|
"../../global_oce_llc90/code/" If you move global_oce_llc90 away from |
|
|
global_oce_cs32 you will need to edit that path in genmake_local. |
|
|
1.3) in analogy input*/prepare_run are a set of instructions that "testreport" |
|
|
will execute before running MITgcm, to link all of the proper inputs. |
|
|
And again the experiments form a self-consistent group, such that |
|
|
e.g. global_oce_cs32 will get shared files from global_oce_llc90. If you move |
|
|
the directories appart, you will need to edit the paths in input*/prepare_run |
|
|
1.4) the logic we followed in linking exps to one another : |
|
|
- forward subexperiments : get local namelists then run input/prepare_run |
|
|
- adjoint subexperiments : get input_ad.x/namelists then run corresponding forward |
|
|
subexperiment input.x/prepare_run (that itself ultimately runs input/prepare_run) |
|
|
|
|
|
2) In a couple .h files (that you find in the build directory after compiling) |
|
|
small size parameters are used as a default (to save memory of course) |
|
|
and they can become limiting in certain cases : |
|
|
- you may want to integrate the model beyond a few time steps. You will need to |
|
|
edit ecco_cost.h, increase nchklev_1, nchklev_2, nchklev_3 and recompile. |
|
|
- you may want to use pkg/profiles (i.e. process insitu data via data.profiles). |
|
|
You will need to edit profiles.h to increase NOBSGLOB, and recompile. |
|
|
|
|
|
3) To run the adjoint subexperiments you need the taf/tamc software/license. |
