It is mandatory to install :
Fortran 90 compiler
netCDF library compiled with real*8
It is necessary to put in place the make files that will be used to generate the executables.
The makefiles depend on the platform and are generated by the files :
AA_make.ldef
AA_make.gdef
AA_make
The makefiles are generated by the ins_make commande as follows :
| rhodes : ins_make [-t sxnec] |
Below is some help on the ins_make command :
- Usage : ins_make [-h] [-v] [-d] [-p r] [-t h]
- -h : help
- -v : verbose mode
- -t h : target host_name
- -d : debug mode
- -p r : real_precision 4/8
-
- Example for remote host compilation
- ins_make -t sxnec
-
- Default : -t local_host
-
To create the librairies and the executables, the gmake command must
be entered in the IPSLCM4_v1 directory. The default mode generates the
executables in low resolution (ORCA4xLMD7245). To generate the
executables in medium resolution the argument ORCA2xLMD9671 must be
passed to gmake at the first call.
For each resolution a .resol file is generated, containing the
resolution chosen at the time of first compilation of the model.
For the following calls gmake can be called without the argument, the
initial resolution is remebered.
N.B. :The .resol file is only created if first compilation ran correctly.
N.B. : The .resol file is only relevant for the directory in
which it lies.
The next two paragraphs give the instructions to follow depending on
the resolution in which the model was compiled.
| rhodes : cd ../modeles/IPSLCM4_v1 |
NOT TO BE FORGOTTEN !!! |
| rhodes : gmake |
Executables
and librairies creation
for the low resolution |
| rhodes : cd ../modeles/IPSLCM4_v1 |
NOT TO BE FORGOTTEN !!! |
| rhodes : gmake ORCA2xLMD9671 |
Executables
and librairies creation
for the medium resolution |
The compilation of IPSL Coupled model is a 5 step process :
IOIPSL compilation
OASIS compilation
ORCHIDEE compilation
LMDZ comilation
ORCA + LIM compilation
Following this, compilation can be considered as having been
successful if the following message appears :
In medium resolution
Figure 2.4 : Medium resolution compilation
 |
In low resolution
Figure 2.5 : Low resolution compilation
 |
General points :
The whole package must be compiled
with the REAL*8 option (REAL*4 will not work). This means that
the netCDF library must also be in REAL*8 Problems while running the
Makefile(s) :
if the Makefile seems unable to take
properly in account the source files, i.e you get a message like
"unable to create...", then :
| rhodes : cd modeles/OPA ; ../UTIL/fait_AA_make |
| rhodes : cd ../"MODEL_NAME"; ../../util/ins_make [options] |
and try again...
In case of successful compilation of the selected model, a .resol file
has been generated and contains the information on the resolution in
which was made the inital compilation. However the model must be
recompiled after each modification in the sources. The needed commands
are very simple :
| rhodes : cd STD_TEST/modipsl/modeles/IPSLCM4_v1 |
|
| rhodes : cat .resol |
Optional resolution verification |
| rhodes : gmake |
Executables
and librairies creation
for the resolution
specified in .resol |
