+# How to use the IPSL models and tools with a local PC #
+
+## Compiling ##
+### Choosing a target in AA_make.gdef ###
+The ins_make script from modipsl will probably not recognize the local PC to create makefiles. You must then choose or create a new target in the util/AA_make.gdef file, adapt it to its new computing environment (compiler, options, netcdf  path,etc), and create a new makefile with 
+{{{
+./ins_make -t new_target
+}}}
+
+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 models. [[BR]]
+
+### An example for IOIPSL and ORCHIDEE ###
+To compile IOIPSL and ORCHIDEE, for instance, we recommend the gfortran compiler with the gfortran target in AA_make.gef. You must check and adapt the NetCDF path before creating new makefiles with ./ins_make -t gfortran. 
+{{{
+cd modipsl/util
+vi AA_make.gdef   # Check the following lines:
+   #-Q- gfortran  NCDF_INC = /usr/local/include
+   #-Q- gfortran  NCDF_LIB = -L/usr/local/lib -lnetcdf
+./ins_make -t gfortran
+}}}
+
+
+## Simulation with libIGCM ##
+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]]
+
+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.
+
+## Installing rebuild ##
+The output of most of the models (ORCHIDEE, LMDZ, INCA, REPROBUS) must be recombined to the total horizontal domain when simulation is done in parallele mode. 
+
+The tool for this is 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. 
+
+'''Installation''' 
+
+{{{
+cd modipsl/util
+./model IOIPSL_PLUS
+# Modify AA_make.gdef for the compiling as above
+./ins_make -t new_target
+cd ../modeles/IOIPSL/tools
+gmake
+}}}
+
+
+For use with libIGCM, add the path to your rebuild in libIGCM_sys/libIGCM_sys_default.ksh. 
+
+'''Use in interactive mode'''[[BR]]
+
+rebuild can also be used interactively. For example create the global file sechiba_history.nc as following :
+
+{{{
+./rebuild -h
+./rebuild -o sechiba_history.nc sechiba_history_00*
+}}}
