L. Fita's work-flow management for ORCHIDEE model

ORCHIDEE work-flow management is done via 3 scripts (these are the specifics for hydra [CIMA cluster]):

  • EXPERIMENTparameters.txt: General ASCII file which configures the experiment and chain of simulations (chunks). This is the unique file to modify
  • run_experiments.pbs: PBS-queue job which prepares the experiment of the environment
  • run_OR.pbs: PBS-queue job which launch the ORCHIDEE model and a range the output
  • There is a folder called components with shell and python scripts necessary for the work-flow management

An experiment which contains a period of simulation is divided by chunks small pieces of times which are manageable by the model. The work-flow follows these steps using run_experiments.pbs:

  1. Copy and link all the required files for a given chunk of the whole period of simulation following the content of EXPERIMENTparameters.txt
  2. Launches run_OR.pbs which will simulated the period of the given chunk
  3. Launches the next run_experiments.pbs (which waits until the end of run_OR.pbs)

All the scripts are located in hydra at: 

/share/tools/work-flows/OR4L/hydra

How to simulate

  1. Creation of a new folder from where launch the experiment [ExperimentName] 
$ mkdir [ExperimentName]
cd [ExperimentName]
  1. copy the OR4L files to this folder 
$ cp /share/tools/work-flows/OR4L/hydra/EXPERIMENTparameters.txt ./
$ cp /share/tools/work-flows/OR4L/hydra/run_experiment.pbs ./
$ cp /share/tools/work-flows/OR4L/hydra/run_OR.pbs ./
  1. Edit the configuration/set-up of the simulation of the experiment 
$ vim EXPERIMENTparameters.txt
  1. Launch the simulation of the experiment 
$ qsub run_experiment.pbs

When it is running one would have (runnig ORCHIDEE job or_[SimName] `R', and exp_[SimName] in hold `H'): 

$ qstat -u $USER

hydra: 
                                                                         Req'd  Req'd   Elap
Job ID               Username Queue    Jobname          SessID NDS   TSK Memory Time  S Time
-------------------- -------- -------- ---------------- ------ ----- --- ------ ----- - -----
397.hydra            lluis.fi larga    or_oF-OKstomate_  27567     1  16   20gb 168:0 R   -- 
398.hydra            lluis.fi larga    exp_oF-OKstomate    --      1   1    2gb 168:0 H   --

In case of crash of the simulation, after fixing the issue, go to [runHOME]/[ExpName]/[SimName] and re-launch the experiment (after the first run the scratch is switched automatically to `false') 

$ qsub run_experiment.pbs

Checking the experiment

Once the experiment runs, one needs to look on (following name of the variables from EXPERIMENTparameters.txt

  • [runHOME]/[ExpName]/[SimName]: Will content the copies of the templates run.def, *.xml and a file chunk_attemps.inf which counts how many times a chunk has been attempted to be run (if it reached 4 times, the OPR4L is stopped)
  • [runHOME]/[ExpName]/[SimName]/run: actual folder where the computing nodes run the model. In a folder called orout there is a folder for each chunk with the standard output of the model
  • [runHOME]/[ExpName]/[SimName]/run/orout/[YYYYi][MMi][DDi][HHi][MIi][SSi]-[YYYYf][MMf][DDf][HHf][MIf][SSf]: folder with the standard output and all the required files to run a given chunk. The content of all this folder is compressed and kept in [storageHOME]/[ExpName]/[SimName]/config_[YYYYi][MMi][DDi][HHi][MIi][SSi]-[YYYYf][MMf][DDf][HHf][MIf][SSf].tar.gz
  • [storageHOME]/[ExpName]/[SimName] (in [storageHOST]): output of the already ran chunks as [YYYYi][MMi][DDi][HHi][MIi][SSi]-[YYYYf][MMf][DDf][HHf][MIf][SSf] for a chunk from [YYYYi]/[MMi]/[DDi] [HHi]:[MIi]:[SSi] to [YYYYf]/[MMf]/[DDf] [HHf]:[MIf]:[SSf]

When something went wrong

If there has been any problem check the last chunk (in orout/[PERIODchunk]) to try to understand what happens and where the problem comes from:

  • out_orchidee_[nnnn]: These are the files which content the standard output while running the model. One file for each process. If the problem was something related to model execution and it has been prepared for the error, a correct message must appear. (look first for the largest files... 
$ ls -lrS out_orchidee_*
  • run_or.log: These are the files which content the standard output of the model. Search for `segmentation faults', etc...

EXPERIMENTSparameters.txt

This ASCII file configures all the simulation. It assumes:

  • Required files, forcings, storage, compiled version of the code might be at different machines.
  • There is a folder with a given template version of the run.def which will be used and changed accordingly to the requirement of the experiments

Name of the experiment 

# Experiment name
ExpName = DiPolo

Name of the simulation. Here is understood that a given experiment could have the model configured with different set-ups (here identified with a different name of simulation) 

# Simulation name
SimName = OKstomate_CRUNCEP_spinup

Which binary of python 2.x to be used 

# python binary
pyBIN=/home/lluis.fita/bin/anaconda2/bin/python

Should this simulation be run from the beginning or not. If it is set to `true', it will remove all the pre-existing content of the folder [ExpName]/[SimName] in the running and in the storage spaces. Be careful. In case of `false' simulation will continue from the last successful ran chunk (checking the restart files). 

# Start from the beginning (keeping folder structure)
scratch = false

Period of the simulation of the simulation (In this example from 1958 Jan 1st to 2015 Dec 31) 

# Experiment starting date
exp_start_date = 19580101000000
# Experiment ending date
exp_end_date = 20150101000000

Length of the chunks (here and in all ORCHIDEE runs maximum to 1-year!!) 

# Chunk Length [N]@[unit]
#  [unit]=[year, month, week, day, hour, minute, second]
chunk_length = 1@year

Selection of the machines and users to each machine where the different requirement files are located and the output should be placed.

  • NOTE: this will only work if one set-up the .ssh public/private keys in each involved USER/HOST.
  • NOTE 2: All the forcings, compiled code, ... are already at hydra at the common space called share
  • NOTE 3: From the computing nodes, one can not access to the /share folder and to any of the CIMA's storage machines: skogul, freyja, ... For that reason, one need to use these system of [USER]@[HOST] accounts. *.pbs scripts uses a series of wrappers of the standard functions: cp, ln, ls, mv, .... which manage them `from' and `to' different pairs of [USER]@[HOST] 
# Hosts
#   list of different hosts and specific user
#     [USER]@[HOST]
#   NOTE: this will only work if public keys have been set-up
##
# Host with compiled code, namelist templates
codeHOST=lluis.fita@hydra
# forcing Host with forcings (atmospherics and morphologicals)
forcingHOST=lluis.fita@hydra
# output Host with storage of output (including restarts)
outHOST=lluis.fita@hydra

Templates of the configuration of ORCHIDEE: run.def, *.xml files. NOTE: only run.def will be changed according to the content of EXPERIMENTparameters.txt like period of the chunk, atmospheric forcing, differences of the set-up, ... (located in the [codeHOST] 

# Folder with the `run.def' and `xml' of the experiment
domainHOME = /home/lluis.fita/salidas/estudios/dominios/DiPolo/daily

Folder where the ORCHIDEE model will run in the computing nodes (on top of that there will be two more folders [ExpName]/[SimName]). ORCHIDEE will run at the folder [ExpName]/[SimName]/run 

# Running folder
runHOME = /home/lluis.fita/estudios/DiPolo/sims

Folder with the compiled version of the model (located at [codeHOST]) 

# Folder with the compiled source of ORCHIDEE
orHOME = /share/modipsl/bin/

Folder to storage all the output of the model (history files, restarts and compressed file with content of the configuration and the standard output of the given run). The content of the folder will be organized by chunks (located at [storageHOST]) 

# Storage folder of the output
storageHOME = /home/lluis.fita/salidas/estudios/DiPolo/sims/output

Wether modules should be load (not used for hydra) 

# Modules to load ('None' for any)
modulesLOAD = None

Which kind of simulation will be run (at this time only prepared for 'offline') 

# Simulation kind
#  'offline': Realistic off-line run, with initial conditions at each change of year
#  'periodic': Realistic off-line run, with the same initial conditions for each year
kindSIM = offline

Names of the files used to check that the chunk has properly ran 

# Model reference output names (to be used as checking file names)
nameLISTfile = run.def # namelist
nameRSTfile = sechiba_rest_out.nc # restart file
nameOUTfile = sechiba_history.nc # output file

Extensions of the files which content the configuration of the model 

# Extensions of the files with the configuration of the model
configEXTS = def:xml

To continue from a previous chunk one needs to use the `restart' files. But they need to be renamed, because otherwise they will be re-written. Here one specifies the original name of the file [origFile] and the name to be used to avoid the re-writting [destFile]. It uses a complex bash script which even can deal with the change of dates according to the period of the chunk (':' list of [origFile]@[destFile]). They will located at the [storageHOST]

Files to be used as atmospheric forcings (It uses the same complex bash script as in the restarts). Files must be located at [forcingHOST]. In this example a CRU-NCEP file which is called cruncep_halfdeg_[YYYY].nc (where [YYYY] is for a year in four digits). It is said to change the [YYYY] by %Y% which will be the year of the chunk with four digits (C-like)

ORCHIDEE off-line can not run with the parallel-netCDF. For that reason, output files are written for each computing node. At the end of the simulation they need to be concatenated with the tool flio_rbld (Already compiled in hydra). This is done automatically at the end of the simulation. (to be found at [codeHOST])
