To this end\, see the chapter [wiki:DocBenv 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. Therefor no specific installation is needed anymore. If no fcm is available in the source directory, then fcm must then be installed and added to your environemental variable PATH. At following machines, fcm is already installed {{{ # 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''' 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. These files have the name of the machine as a prefix : arch-X64_CURIE.fcm, arch-X64_CURIE.path # Creating the main makefile # '''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 [wiki:DocHconfigHorchideeol#Specialcompilingcases ORCHIDEE_OL] and for [wiki:DocHconfigGnemo#SettingupNEMOwiththemodipslenvironment 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. [[BR]] Example : {{{ #!sh 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. {{{ #!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- ada (...) #-Q- curie (...) #-Q- aix6 (...) #-Q- gfortran (...) }}} In this case, the script becomes {{{ #!sh ./ins_make -t cible }}} # The main makefile # 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 : * LMD4443 * LMD5655 * LMD9671 * LMD9695 * LMD9695-L39 * LMD144142 * LMD144142-L39 Another feature of the Makefile is ability to compile any model with the chosen resolution. For '''''_v5''''' configurations, the default resolution is 96x95x39. # How to compile? # Once you chose a resolution you can start compiling: {{{ #!sh gmake ma_resolution }}} For the default resolution gmake is fine. Example for LMDZOR_v5: {{{ #!sh 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. [[BR]]Going back to the previous example, the .resol file looks as follows : {{{ ORCAxLMD144142-L39 RESOL_ATM_3D=144x142x39 }}} [[NoteBox(note,Once the file '''.resol''' is created\, you can recompile your configuration using the gmake script without specifying the resolution., 600px)]] # How to optimize the compilation # * You can change your optimization options for the ORCHIDEE and 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 INCA and LMDZ models are predefined in the arch/ files.You can select them in the modipsl/config/.../Makefile file. The three options are: '''-debug''', '''-dev''', '''-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)]]
