| 40 | | # How to use the IPSL models and tools with a local PC # |
| 41 | | Compiling and running tools are set up by default for known IPSL computing centers. If you need to work on a local PC or another computing cluster, you need to adapt the compilation and running options. |
| 42 | | |
| 43 | | ## Compiling ## |
| 44 | | It is recommended to first make a test installation of XIOS following the guide here: http://forge.ipsl.jussieu.fr/ioserver/wiki/documentation |
| 45 | | Then use the same libraries and compiler versions for all components as for XIOS. |
| 46 | | |
| 47 | | Some configurations can be installed without XIOS. |
| 48 | | |
| 49 | | |
| 50 | | ### Choose a target in AA_make.gdef ### |
| 51 | | The ins_make script from modipsl will not recognize your local PC to create makefiles. You must specify an existing target or create a new target in the util/AA_make.gdef file. Adapt this target to your computing environment (compiler, options, path to netcdf, etc), and create a new makefile specifying this target: |
| 52 | | {{{ |
| 53 | | ./ins_make -t new_target |
| 54 | | }}} |
| 55 | | |
| 56 | | Please refer to the model managers of your model configuration to learn more about how to compile the IPSL models on a local PC and which compilers can be used with the specific models you need. [[BR]] |
| 57 | | |
| 58 | | ### Example for installing ORCHIDEE offline ### |
| 59 | | Before installing ORCHIDEE, make a test installation of XIOS, see guide here: http://forge.ipsl.jussieu.fr/ioserver/wiki/documentation . If this fails, it is still possible to install ORCHIDEE without XIOS, see notes below. |

| 61 | | {{{ |
| 62 | | # 1. Install a new modipsl |
| 63 | | svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl |
| 64 | | |
| 65 | | |
| 66 | | # 2. Install the configuration ORCHIDEE_trunk |
| 67 | | cd modipsl/util |
| 68 | | ./model ORCHIDEE_trunk |
| 69 | | |
| 70 | | |
| 71 | | # 3. Adapt and add compile options to your machine |
| 72 | | |
| 73 | | # 3a. Compile options for component IOIPSL: |
| 74 | | # Add a section NEW_ARCH in modipsl/util/AA_make.gdef |
| 75 | | # Do this by coping the section ifort_CICLAD for example and adapt all options according to your machine and your compiler. |
| 76 | | # Make sur to have the variable FCM_ARCH correct as follow: |
| 77 | | #-Q- NEW_ARCH FCM_ARCH = NEW_ARCH |
| 78 | | |
| 79 | | # 3b. Add compile options for component XIOS |
| 80 | | # Add following files (by coping and adapting one of the existing targets closest to your machine) |
| 81 | | modipsl/modeles/XIOS/arch/arch_NEW_ARCH.fcm |
| 82 | | modipsl/modeles/XIOS/arch/arch_NEW_ARCH.path |
| 83 | | modipsl/modeles/XIOS/arch/arch_NEW_ARCH.env |
| 84 | | |
| 85 | | # Note: the netcdf4 library can be parallel or sequential, depending on the version. If the sequential netcdf4 library is used, some functionalities in XIOS can not be used such us using several servers. To link XIOS to the sequantial library, the argument --netcdf_lib netcdf4_seq when compiling XIOS. This should be added in modipsl/config/ORCHIDEE_OL/AA_make just after ./make_xios --netcdf_lib netcdf4_seq ... |
| 86 | | |
| 87 | | |
| 88 | | # 3b. Add compile options for component ORCHIDEE |
| 89 | | # Add following files (by coping and adapting one of the existing targets closest to your machine) |

| 102 | | gmake |
| 103 | | }}} |
| 104 | | Notes: |
| 105 | | * The name NEW_ARCH can be changed to another name but needs to be same everywhere |
| 106 | | * All arch_NEW_ARCH.* files and AA_make.gdef must be coherent for the libraries and options choosen |
| 107 | | * It is still possible to install without XIOS. For that case, you do not need to do 3b above and the compilation is done using '''gmake without_xios''' |

| 110 | | ### Example for installing LMDZOR_v5.2 sequential mode with gfortran ### |
| 111 | | {{{ |
| 112 | | # 1. Install configuration LMDZOR_v5.2 in a new modipsl |
| 113 | | svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl |
| 114 | | cd modipsl/util; ./model LMDZOR_v5.2 |
| 115 | | |
| 116 | | # 2. Adapt the path to your netcdf which must also be compiled with gfortran, in 3 files: |
| 117 | | modipsl/modeles/LMDZ/arch/arch-gfortran.path |
| 118 | | modipsl/modeles/ORCHIDEE/arch/arch-gfortran.path |
| 119 | | modipsl/util/AA_make.gdef (section gfortran) |
| 120 | | |
| 121 | | # 3. Change default compiling to sequential run mode in main makefile. |
| 122 | | In modipsl/config/LMDZOR_v5.2/AA_make |
| 123 | | change "-parallel mpi" into "-parallel none" at 3 places. |
| 124 | | The name of the executables changes also, therefore change "_phylmd_para_orch.e" into "_phylmd_seq_orch.e" at 2 places |
| 125 | | |
| 126 | | # 4. Recreate makefiles with target gfortran |
| 127 | | cd modipsl/util |
| 128 | | ./ins_make -t gfortran |
| 129 | | |
| 130 | | # 5. Compile as usual |
| 131 | | cd modipsl/config/LMDZOR_v5.2; gmake |
| 132 | | }}} |
| 133 | | |
| 134 | | |
| 135 | | Note 1: for installing in parallel mode with MPI, do as above but adapt the files arch-gfortran.path, arch-gfortran.fcm and AA_make.gef with suitable compile options. You can use target gfortran_CICLAD in AA_make.gdef as example. Do not do point 3 above. [[BR]] |
| 136 | | |
| 137 | | Note 2: for older version of ORCHIDEE, such as in LMDZOR_v5, the files in modeles/ORCHIDEE/arch do not exist. Compile options in AA_make.gdef is used for ORCHIDEE in this case. |
| 138 | | |
| 139 | | [[NoteBox(note,The v6 configurations cannot be compiled in sequential mode because XIOS do not compile or run without the MPI library., 600px)]] |
| 140 | | |
| 141 | | |
| 142 | | ## Simulation with libIGCM ## |
| 143 | | When using libIGCM on a local PC, the parameters of the default system described in the libIGCM_sys/libIGCM_sys_default.ksh file will be used. You may have to change this file to match your system. [[BR]] |
| 144 | | |
| 145 | | A minimum subset of files located on the shared IGCM account must be downloaded and installed. This directory is called R_IN in libIGCM_sys_default.ksh and it has the default path /home/${LOGIN}/IGCM. |
| 146 | | |
| 147 | | ## Installing rebuild ## |
| 148 | | The output of old version of the models (ORCHIDEE, LMDZ, INCA, REPROBUS) must be recombined to the total horizontal domain when simulation is done in parallel mode. |
| 149 | | |
| 150 | | The tool for this is called ''rebuild''. The rebuild tool is called in the post-processing phase by libIGCM. rebuild is a fortran code included in IOIPSL. rebuild must be installed and compiled on the local machine. The rebuild can then be used interactively outside libIGCM or in the post-processing phase. |
| 151 | | |
| 152 | | '''Installation''' |
| 153 | | |
| 154 | | {{{ |
| 155 | | cd modipsl/util |
| 156 | | ./model IOIPSL_PLUS |
| 157 | | # Modify AA_make.gdef for the compiling as above |
| 158 | | ./ins_make -t new_target |
| 159 | | cd ../modeles/IOIPSL/tools |
| 160 | | gmake |
| 161 | | }}} |
| 162 | | |
| 163 | | |
| 164 | | For use with libIGCM, add the path to your rebuild in libIGCM_sys/libIGCM_sys_default.ksh. |
| 165 | | |
| 166 | | '''Use in interactive mode'''[[BR]] |
| 167 | | |
| 168 | | rebuild can also be used interactively. For example create the global file sechiba_history.nc as following : |
| 169 | | |
| 170 | | {{{ |
| 171 | | ./rebuild -h |
| 172 | | ./rebuild -o sechiba_history.nc sechiba_history_00* |
| 173 | | }}} |
