  29. Time Series : create_ts.job • A Time Series is a file which contains a single variable over the whole simulation period (ChunckJob2D = NONE) or for a shorter period for 2D (ChunckJob2D = 100Y) or 3D (ChunckJob3D = 50Y) variables. • The write frequency is defined in theconfig.cardfile: TimeSeriesFrequency=10Yindicates that the time series will be written every 10 years and for 10-year periods. • The Time Series are set in the COMP/*.card files by the TimeSeriesVars2D and TimeSeriesVars3D options. • The Time Series coming from monthly (or daily) output files are stored on the file server in the IGCM_OUT/TagName/[SpaceName]/[ExperimentName]/JobName/Composante/Analyse/TS_MO and TS_DA directories. • Bonus : TS_MO_YE (for annual mean time series) are produced for all TS_MO variables • You can add or remove variables to the TimeSeries lists according to your needs. [Post] ... #D- If you want to produce time series, this flag determines #D- frequency of post-processing submission (NONE if you don't want) TimeSeriesFrequency=10Y config.card • [OutputFiles] • List= (histmth.nc, ${R_OUT_ATM_O_M}/${PREFIX}_1M_histmth.nc, Post_1M_histmth),\ • ... • [Post_1M_histmth] • Patches= () • GatherWithInternal = (lon, lat, presnivs, time_counter, time_counter_bnds, aire) • TimeSeriesVars2D = (bils, cldh, ... • ... • ChunckJob2D = NONE • TimeSeriesVars3D = (upwd, lwcon, ... • ... • ChunckJob3D = OFF COMP/lmdz.card

  30. MONITORING : dods

  31. Intermonitoring : http://webservices.ipsl.jussieu.fr/monitoring/

  32. How to add a new variable in MONITORING • You can add or change the variables to be monitored by editing the configuration files of the monitoring. Those files are defined by default for each component. • The monitoring is defined here: ~compte_commun/atlas For example for LMDZ on curie : ~p86ipsl/monitoring01_lmdz_LMD9695.cfgFor example for LMDZ on adapp : ~rpsl035/monitoring01_lmdz_LMD9695.cfg • You can change the monitoring by creating a POST directory which is part of your configuration. Copy a .cfg file and change it the way you want. • use ferret language • You can monitor variables produced in time series and stored in TS_MO POST/monitoring01_lmdz_LMD9695.cfg • #-------------------------------------------------------------------------------------------------------- • # field | files patterns | files additionnal | operations | title | units | calcul of area • #-------------------------------------------------------------------------------------------------------- • nettop_global | "tops topl" | LMDZ4.0_9695_grid.nc | "(tops[d=1]-topl[d=2])" | "TOA. total heat flux (GLOBAL)" | "W/m^2" | "aire[d=3]"

  33. Seasonal mean : create_se.job • A seasonal means files (SE) contain averages for each month of the year (jan, feb,...) for a frequency defined in the config.card files • SeasonalFrequency=10Y The seasonal means will be computed every 10 years. • SeasonalFrequencyOffset=0 The number of years to be skipped for calculating seasonal means. • All files with a requested Post (Seasonal=ON in COMP/*card) are then averaged within the ncra script before being stored in the directory: • IGCM_OUT/IPSLCM5A/DEVT/pdControl/MyExp/ATM/Analyse/SE. There is one file per SeasonalFrequency=10Y • ATLAS are launched by create_se. ATLAS sources are : ~rpsl035 ~p86ipsl/atlas #======================================================================== #D-- Post - [Post] ... #D- If you want to produce seasonal average, this flag determines #D- the period of this average (NONE if you don't want) SeasonalFrequency=10Y #D- Offset for seasonal average first start dates ; same unit as SeasonalFrequency #D- Usefull if you do not want to consider the first X simulation's years SeasonalFrequencyOffset=0 config.card • [OutputFiles] • List=(histmth.nc, ${R_OUT_ATM_O_M}/${PREFIX}_1M_histmth.nc, Post_1M_histmth),\ • ... • [Post_1M_histmth] • ... • Seasonal=ON COMP/lmdz.card

  35. Monitoring the simulation Verification and Correction

  36. Monitoring a simulation • We strongly encourage you to check your simulation frequently during run time. First of all, check job status : ccc_mstat llq • Real time limit exceeded : jobs are killed without any message on ada • RunChecker.job : This tool, provided with libIGCM, allows you to find out your simulations' status. • One historical simulation, 156 years : 1850-2005 is composed by 50 computing jobs and 1000 post-processing jobs Documentation http://forge.ipsl.jussieu.fr/igcmg/wiki/platform/en/documentation

  37. Monitoring a simulation : mail • You receive a message at the end of the simulation • The simulation could be completed or failed De : rpsl003@idris.fr Objet : COURSNIV2 completed Date : 22 octobre 2013 18:29:24 UTC+02:00 À : rpsl003@idris.fr Dear rpsl003, Simulation COURSNIV2 completed on supercomputer ada027 Simulation started : 20000101 Simulation ended : 20000102 Output files are available in /u/rech/psl/rpsl003/IGCM_OUT/IPSLCM5A/DEVT/pdControl/COURSNIV2 Files to be rebuild are temporarily available in /workgpfs/rech/psl/rpsl003/IGCM_OUT/IPSLCM5A/DEVT/pdControl/COURSNIV2/REBUILD Pre-packed files are temporarily available in /workgpfs/rech/psl/rpsl003/IGCM_OUT/IPSLCM5A/DEVT/pdControl/COURSNIV2 Script files, Script Outputs and Debug files (if necessary) are available in /gpfs5r/workgpfs/rech/psl/rpsl003/ADA/COURS/NIV2/IPSLCM5_v5/modipsl/config/IPSLCM5_v5/COURSNIV2 Greetings!

  38. Monitoring a simulation : run.card • When the simulation has started, the file run.card is created by libIGCM using the template run.card.init. • run.cardcontains information of the current run period and the previous periods already finished. • This file is updated at each run period by libIGCM. • You can find here information of the time consumption of each period. • The status of the job is set to OnQueue, Running, Completed or Fatal.

  39. Verification and correction 1/6 • Where did the problem occur ? • 1 "failed" email : Main computation job => gaya stopped at IDRIS, hardware problem ? Check Script_output_xxxx. => When gaya restarted, or if there isn't any clear error message, try relaunching (after a clean_month): path/to/libIGCM/clean_month.job ccc_msub (llsubmit) Job_...

  40. Verification and correction 2/6 • Where did the problem occur ? • 1 "failed" email : Main computation job : analyse Script_output_xxxx ####################################### # ANOTHER GREAT SIMULATION # ####################################### 1ère partie (copying the input files) ####################################### # DIR BEFORE RUN EXECUTION # ####################################### 2ème partie (running the model) ####################################### # DIR AFTER RUN EXECUTION # ####################################### 3ème partie (post-processing) ####################################### http://forge.ipsl.jussieu.fr/igcmg/wiki/platform/en/documentation/G_suivi#AnalyzingtheJoboutput:Script_Output

  41. Verification and correction 3/6 --> analyse Script_output_xxxx : In general, if your simulation stops you can look for the keyword "IGCM_debug_CallStack" in this file. This keyword will come after a line explaining the error you are experiencing. ===================================================================== EXECUTION of : mpirun -f ./run_file > out_run_file 2>&1 Return code of executable : 1 IGCM_debug_Exit : EXECUTABLE !!!!!!!!!!!!!!!!!!!!!!!!!! !! IGCM_debug_CallStack !! !------------------------! !------------------------! IGCM_sys_Cp : out_run_file xxxxxxxxxxxx_out_run_file_error =====================================================================

  42. Verification and correction 4/6 --> Check closely the sub directory Debug (if it exists) Check file xxxxx_error in Debug/ : • contains LMDZ standard output. LMDZ often fails in hgardfou. Stopping in hgardfou • contains abends (abnormal termination / exception) of each and every component. Check standard outputs for NEMO, ORCHIDEE, INCA, OASIS • Debug/xxxx_ocean.output • Debug/xxxx_output_orchidee • Debug/xxxx_inca.out • Debug/xxxx_cplout

  43. RunChecker.job • RunChecker.job helps you to monitor all the jobs produced by libIGCM for a simulation

  44. RunChecker.job : usage and options This script can be launched from anywhere. Usage: path/to/libIGCM/RunChecker.job [-u user] [-q] [-j n] [-s] job_name path/to/libIGCM/RunChecker.job [-u user] [-q] [-j n] -p config.card_path path/to/libIGCM/RunChecker.job [-u user] [-q] [-j n] -r Options : -h : print this help and exit -u user : owner of the job -q : quiet -j n : print n post-processing jobs (default is 20) -s : search for a new job in $WORKDIR and fill in the catalog before printing information -p path : give the absolute path to the directory containing the config.card instead of the job name (needed only once) -r : check all running simulations. 1) path/to/libIGCM/RunCkecker.job –p $CCCWORKDIR/CURIE/CMIP5/R1414/IPSLCM5A_20120731/modipsl/config/IPSLCM5A/v5.rcp45CMR2 2) path/to/libIGCM/RunCkecker.job v5.rcp45CMR2

  45. STOP (Fatal into run.card) Pb !

  46. Verification and correction 5/6 • You have received 2 "failed" emails or RunChecker status is abnormal ie : red • Analyse the situation: • Simple case: • Re-submit rebuild, pack_debug or pack_restart jobs • Re-submit pack_output • Less simple case: • Use clean_year to go back to a healthy situation • Holes in the data path/to/libIGCM/clean_year.job [SSAA] • all data from current year to SSAA (included) will be deleted. • Restart the simulation https://forge.ipsl.jussieu.fr/igcmg/wiki/platform/en/documentation/G_suivi#Startorrestartpostprocessingjobs1

  47. TimeSeries_Checker.job • Install a dedicated directory • Copy required files and directories : config.card, run.card, COMP, POST • Copy from libIGCM the script : TimeSeries_Checker.job • Modify the job : libIGCM, name of the simulation, ... • Look at the documentation :https://forge.ipsl.jussieu.fr/igcmg/wiki/platform/en/documentation/G_suivi#TimeSeries_checker.job-Recommendedmethod > mkdir POST_REDO > cd POST_REDO > cp –pr COMP POST config.card run.card . > cp ../../../../libIGCM/TimeSeries_Checker.job . > vi TimeSeries_Checker.job # Check/Modify : libIGCM= SpaceName= ExperimentName= JobName= CARD_DIR= BRIDGE_MSUB_PROJECT=gen2211 > ./TimeSeries_Checker.job Answer y to submit create_ts.job ksh > ./TimeSeries_Checker.job 2>&1|tee TSC_OUT_TO_KEEP

  48. Verification and correction 6/6 • Everything went ok : • End of simulation email • No anomaly detected by RunChecker • TimeSeriesChecker (and SE_checker):Checks existing time series et submit create_ts jobs to build the missing ones • Keep in mind: • Rebuild jobs automatically submit pack jobs, as well as corresponding TS and SE. • Pack, TS and SE jobs may be re-submitted independently from a rebuild job
