LMDZ / std

Description

This is the plugin to run the model LMDZ. Please see further details on LMDZ itself here

Yaml arguments

The following arguments are used to configure the plugin. pyCIF will return an exception at the initialization if mandatory arguments are not specified, or if any argument does not fit accepted values or type:

Mandatory arguments

fileexec: (mandatory)

path to DISPERSION executable

accepted type: <class ‘str’>

file_controle: (mandatory)

path to a restart file. It is used to update the controle variables in the initial condition files. It is especially important when directly interpolating initial conditions from another dataset. It is also used to update the initial date if different from the restart provided in the data vector

accepted type: <class ‘str’>

Optional arguments

autoflush: (optional): True

Clean sub-directories of temporary files (mod.bin, etc.)

accepted type: <class ‘bool’>

periods: (optional): 1MS

Frequency for sub-simulations

accepted type: <class ‘str’>

flx_tresol: (optional): 1D

Expected time step between flux values in the executable

accepted type: <class ‘str’>

physic: (optional): True

Use physics in LMDZ

accepted type: <class ‘bool’>

thermals: (optional): False

Use thermals

accepted type: <class ‘bool’>

conv_scheme: (optional): TK

Convection scheme to use for the deep-convection

accepted values:

• TK: Tiedke parametrization; corresponds to convection scheme #2 in LMDZ

• KE: Kerry-Emmanuel parametrization; corresponds to convection scheme #3 in LMDZ

• KT-Them: Kerry-Emmanuel parametrization + thermics; corresponds to convection scheme #30 in LMDZ

dump: (optional): False

Dump trajq as netCDF

accepted type: <class ‘bool’>

do_chemistry: (optional): True

Use the chemistry

accepted type: <class ‘bool’>

auto-recompile: (optional): False

Auto-compile executables before running if executables not available

accepted type: <class ‘bool’>

force-recompile: (optional): False

Force compilation even if executables available

accepted type: <class ‘bool’>

force-compile-stderr: (optional): False

Force printing what happened during compiling

accepted type: <class ‘bool’>

compile-clean: (optional): False

Cleaning repositories before compiling; slows the compilation but prevent side-effects from re-compiling.Can be switched of for minor modifications in the code

accepted type: <class ‘bool’>

compile-mode: (optional): PROD

Compilation mode

accepted values:

• PROD: production mode; all optimizations are activated

• DEBUG: check-all and traceback are activated, hence slowing down the execution

compiler: (optional): ifort

Compiler to use

accepted values: [‘ifort’, ‘gfortran’]

mpirun: (optional): mpirun

path to mpirun

accepted type: <class ‘str’>

run_options: (optional): []

MPI options

nfilun: (optional): 16

Parameter used in LMDZ sources in libf/firtrez/parafilt.h

accepted type: <class ‘int’>

nfilus: (optional): 15

Parameter used in LMDZ sources in libf/firtrez/parafilt.h

accepted type: <class ‘int’>

nproc: (optional)

Force using a given number of processors. By default, LMDZ uses all available processors
