How to compile MICT

Be aware there other ways to compile Orchidee. All of them are valid. But the use of makeorchidee_fcm should make things easier:

  • It enables the compilation with multiple cores at the same time.
  • No need to modify any file to change the compilation mode (prod/dev/debug).
  • Automatically manages all dependencies between files.

Libraries

Since MICT V7.2, XIOS 2 is enabled on MICT. This is a new library to manage the output for history files. It is recommended to use over the old one: IOIPSL. For several reason:

Compilation

There is an implicit step which depends in your architecture (computer). You need to make sure you have chosen the proper libraries (module load ...) to compile Orchidee.

IOIPSL

This library takes care different IO features:

  • Read/write restart files
  • Read/write history files
  • Read configuration file (run.def)
  • Calendar options

Go to IOIPSL source code folder 

cd YOURPATH/modipsl/modeles/IOIPSL/src

Install all makefiles 

../../util/ins_make

Go to the IOIPSL folder 

cd ../IOIPSL/src

Modify the files shown below:

Orchidee-MICT is using lots of variables. So it is necessary to tell IOIPSL increase the maximum allowed.

Compile IOIPSL 

gmake

At this point, chose one those options:

  • MICT + XIOS 2
    • latest versions
    • XIOS included
  • MICT :
    • If you use MICT v7.2 or before you need to stick to this method.
    • You do not want to use XIOS

MICT + XIOS 2 (preferred since MICT v7.2)

More implicit steps: if you are moving for the first time XIOS. Make sure you update modipsl and libIGCM to the latest. Download XIOS again to make sure you are using the proper version.

XIOS is a new Input/Output? library aimed to replace IOIPSL at some point. Currently, it only replaces the write of history files. This means IOIPSL is still required and must be always compiled.

In order to compile Orchidee MICT + XIOS2 + IOPSL, go to the model source code: 

cd YOURPATH/modipsl/modeles/ORCHIDEE

Go to XIOS 2 folder 

cd ../../XIOS

Compile XIOS 2 

./make_xios --prod --arch SUPPORTED_MACHINE --full --j 8

Go to the models source code folder again 

cd ../ORCHIDEE

Compile Orchidee 

./makeorchidee_fcm  -parallel mpi -arch SUPPORTED_MACHINE -xios2 -driver -prod -full -otherexec -j 8

Replace -arch MACHINE with the machine you are working with. Find more information in makeorchidee_fcm -h command.

After that, when you do a modification you can simply run the command line below. So you avoid the whole recompilation from the code: 

./makeorchidee_fcm  -parallel mpi -arch SUPPORTED_MACHINE -xios2 -driver -prod -otherexec -j 8

In some cases it might be necessary to recompile from zero.

MICT (mandatory before MICT v7.2)

In order to compile Orchidee MICT + IOIPSL:

Go to the models source code folder 

cd ../../ORCHIDEE

Compile Orchidee 

./makeorchidee_fcm  -parallel mpi -arch SUPPORTED_MACHINE -driver -prod -full -j 8

Replace -arch MACHINE with the machine you are working with. Find more information in makeorchidee_fcm -h command.

After that, when you do a modification you can simply run the command line below. So you avoid the whole recompilation from the code: 

./makeorchidee_fcm  -parallel mpi -arch SUPPORTED_MACHINE -driver -prod -j 8

In some cases it might be necessary to recompile from zero.

Debug

If you need to debug use: 

./makeorchidee_fcm  -parallel mpi -arch SUPPORTED_MACHINE (-xios2) -driver -debug -full -j (-otherexec) 8

Notes

  • the use of gmake produces an error due to dependencies. For this reason, it is only required to compile orchidee libraries (ioipsl, ...).
  • This guide expects you have selected the proper module libraries in the HPC you are working with.
  • There is a new option for makeorchidee_fcm called otherexec. It creates forcesoil.exe
