To this end\, see the chapter [wiki:Doc/ComputingCenters Computing environments], 600px)]] ## FCM ## Most of IPSL models and components use the '''fcm''' tool for compiling. Recent versions of the models have fcm in their source directory. Therefore no specific installation is needed anymore. If no fcm is available in the source directory, fcm must then be installed and added to your environment variable PATH. At following machines, fcm is already installed {{{ # At TGCC: PATH=`ccc_home -u igcmg`/Tools/fcm/bin:$PATH # At IDRIS: PATH= # At LSCE(obelix): PATH=/home/orchideeshare/igcmg/fcm/FCM_V1.2/bin:$PATH }}} For other machines, extract fcm from svn and add the path to your environment 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, 3 kinds of files '''*.fcm''', '''*.path''', and '''.env''' exist. They provide all the information needed by fcm to create a makefile. These files are stored in the directory arch/ (LMDZ/arch/, INCA/arch/). * *.fcm : contains the compiler information * compiler name * compiling options * options and settings * *.path : contains the library path names. * *.env : contains module to be load to install properly the environment for the compilation of this model. These files have the name of the machine as a prefix : arch-X64_IRENE.fcm, arch-X64_IRENE.path '''Note''' : for configurations IPSLCM, arch files for OASIS and NEMO are taken in `modipsl/config/IPSLCM*/SOURCE/OASIS` and `modipsl/config/IPSLCM6/SOURCE/NEMO` # Compilation for configurations _v6 and _v6.1.* # ## Creating the main makefile ## Each model configuration XXX 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. [[BR]] Example : {{{ #!sh cd modipsl/util ./model LMDZOR_v6.1.10 (...) Makefiles setup, scripts and data for irene Installation in ../config/LMDZOR_v6 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. {{{ #!sh 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. {{{ #!sh vi AA_make.gdef (...) #-Q- jeanzay (...) #-Q- irene (...) #-Q- aix6 (...) #-Q- gfortran (...) }}} In this case, the script becomes {{{ #!sh ./ins_make -t target }}} ## The main makefile ## The Makefile is available for different resolutions.

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. [[BR]]Going back to the previous example, the .resol file looks as follows : {{{ noORCAxLMD144142-L79 RESOL_ATM_3D=144x142x79 }}} [[NoteBox(note,Once the file `.resol` is created\, you can recompile your configuration using the gmake script without specifying the resolution., 600px)]] For ORCHIDEE_OL, the resolution is not specified during run time. Use only '''gmake'''to compile. The file `.resol` will not be created. ## How to change compile options for debugging or optimization of the model? ## * You can change your optimization options for IOIPSL models in the AA_make.gdef file. To this end you must find your target machine and change the associated lines. You will have to recreate the Makefile. * Three levels of optimization for the ORCHIDEE, INCA and LMDZ models are predefined in the `arch/files`.You need to write them in the modipsl/config/.../Makefile file. The three options are: '''-debug''', '''-dev''', '''-prod'''. XIOS offers the same three levels of compilations, accessible through the flags `--debug`, `--dev` and `prod`. [[BR]] 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 ; ) }}} [[NoteBox(note, The default option is `-prod`, 600px)]] # Compilation for configurations _v6.2 and newer configurations #
