The compiling steps are described in this chapter.
First of all, make sure that your working environment contains all the necessary compiling tools. To this end, see the chapter Computing environments
Some IPSL models use the fcm tool to create their makefile (LMDZ, INCA). Fcm may not be available on all computing machines yet but the recent versions of the LMDZ5 model provide the fcm tool with their installation package (LMDZ/tools/fcm/bin/) except for the INCA model for which you must add the following path:
# At TGCC: PATH=~p86ipsl/fcm/bin:$PATH # At IDRIS: PATH=/smphome/rech/psl/rpsl035/FCM/bin:$PATH # At LSCE(obelix): PATH=/home/orchideeshare/igcmg/fcm/FCM_V1.2/bin:$PATH
For other machines, extract fcm from svn and add the path to your environement variable PATH. Extract as follow:
svn co http://forge.ipsl.jussieu.fr/fcm/svn/PATCHED/FCM_V1.2 fcm
For each machine supported by the IPSL tools, two kinds of files *.fcm and *.path are created. They provide all the information needed by fcm to create a makefile. These files are stored in the directory arch/ (LMDZ/arch/, INCA/arch/).
These files have the name of the machine as a prefix : arch-X64_CURIE.fcm, arch-X64_CURIE.path
Note : The compilation of ORCHIDEE_OL and NEMO requires a few special steps. For example, the main Makefile is located in another directory. Read this chapter and the chapter on special cases for ORCHIDEE_OL and for NEMO.
Each model configuration has a main makefile which provides information about each model component's makefiles. The main Makefile is stored in the modipsl/config/XXXX directory. The main Makefile is created when a model configuration is downloaded and installed.
Example :
cd modipsl/util ./model LMDZOR_v5 (...) Makefiles setup, scripts and data for ada Installation in ../config/LMDZOR_v5 Path from Makefile to modipsl/util : ../../util Installation in ../modeles/IOIPSL/src Path from Makefile to modipsl/util : ../../../util Installation in ../modeles/ORCHIDEE/src_global Path from Makefile to modipsl/util : ../../../util Installation in ../modeles/ORCHIDEE/src_parameters Path from Makefile to modipsl/util : ../../../util Installation in ../modeles/ORCHIDEE/src_parallel Path from Makefile to modipsl/util : ../../../util Installation in ../modeles/ORCHIDEE/src_stomate Path from Makefile to modipsl/util : ../../../util Installation in ../modeles/ORCHIDEE/src_sechiba Path from Makefile to modipsl/util : ../../../util Installation in ../modeles/ORCHIDEE Path from Makefile to modipsl/util : ../../util
You can recreate those Makefiles by running the ins_make script. You have to do this if, for example, you changed the path of modipsl.
cd modipsl/util/
./ins_make
The main Makefile is created by concatenating the following 3 items: AA_make.ldef and AA_make located in the directory where the main Makefile will be created, and the lines corresponding explicitly to the target machine of the util/AA_make.gdef file. For each predefined machine the util/AA_make.gdef file contains the compiler settings. If your machine is not included, you can choose a target among the predefined machines in AA_make.gdef or you can add a new one.
vi AA_make.gdef (...) #-Q- ada (...) #-Q- curie (...) #-Q- aix6 (...) #-Q- gfortran (...)
In this case, the script becomes
./ins_make -t cible
The Makefile is available for different resolutions. Example with LMDZOR_v5 :
LMD4443 : libioipsl liborchidee lmdz44x43x19 verif
echo "noORCAxLMD4443" >.resol
echo "RESOL_ATM_3D=44x43x19" >>.resol
LMD5655 : libioipsl liborchidee lmdz56x55x19 verif
echo "noORCAxLMD5655" >.resol
echo "RESOL_ATM_3D=56x55x19" >>.resol
LMD9671 : libioipsl liborchidee lmdz96x71x19 verif
echo "noORCAxLMD9671" >.resol
echo "RESOL_ATM_3D=96x71x19" >>.resol
LMD9695 : libioipsl liborchidee lmdz96x95x19 verif
echo "noORCAxLMD9695" >.resol
echo "RESOL_ATM_3D=96x95x19" >>.resol
LMD9695-L39 : libioipsl liborchidee lmdz96x95x39 verif
echo "noORCAxLMD9695-L39" >.resol
echo "RESOL_ATM_3D=96x95x39" >>.resol
LMD144142 : libioipsl liborchidee lmdz144x142x19 verif
echo "noORCAxLMD144142" >.resol
echo "RESOL_ATM_3D=144x142x19" >>.resol
LMD144142-L39 : libioipsl liborchidee lmdz144x142x39 verif
echo "noORCAxLMD144142-L39" >.resol
echo "RESOL_ATM_3D=144x142x39" >>.resol
Available resolutions are :
Another feature of the Makefile is ability to compile any model with the chosen resolution.
For _v5 configurations, the default resolution is 96x95x39.
Once you chose a resolution you can start compiling:
gmake ma_resolution
For the default resolution gmake is fine. Example for LMDZOR_v5:
cd modipsl/config/LMDZOR_v5
gmake LMD144142-L39
The hidden file .resol is created when compiling was successful. This file contains information about the resolution you have just compiled. This file will be used later when setting up the simulation, in particular to locate the input files.
Going back to the previous example, the .resol file looks as follows :
ORCAxLMD144142-L39 RESOL_ATM_3D=144x142x39
Once the file .resol is created
Example: to compile LMDZ you can add the keyword "-debug" :
(cd ../../modeles/LMDZ; ./makelmdz_fcm (...) -debug (...) -arch $(FCM_ARCH) gcm ; cp bin/gcm_$(RESOL_LMDZ)_phylmd_para_orch.e ../../bin/gcm.e ; )
The default option is -prod
