In the file job_settings environment variables are set for settings the specific requirement for the job. Am example looks like so:

#... change this due to your needs

#... experiment identifier
EXPID=sp001            # alphanumeric characters for job identification

#... directory path settings
SPDIR=?{initSPDIR}  # this is starter package specific and not necessary, if the full paths are defined in the following lines
PFDIR=${SPDIR}/chain/gcm_to_cclm             # base directory where the scripts for the experiment are stored
WORKDIR=${SPDIR}/chain/work                  # NONE of the created files under this directory will be deleted at the end of the job chain
SCRATCHDIR=${SPDIR}/chain/scratch            # ALL created files under this directory will be deleted at the end of the job chain, therefore:
                                             # do not define SCRATCHDIR as any of your other paths!!!
ARCHIVE_INPDIR=${SPDIR}/data/gcm/ncep        # directory of coarse model input data
ARCHIVE_OUTDIR=${SPDIR}/chain/arch           # directory where the results should be archived
RESDIR=${WORKDIR}/${EXPID}/restarts          # restart data directory

#... batch command
BATCH_CMD=sbatch                             # the batch command of your computer system
COMPUTER_SYSTEM=mistral                      # name of your computer system

#... start and end date of the simulation
YDATE_START=2000010100          # start date of simulation YYYYMMDDHH[mmss]
YDATE_STOP=2000030100          # end date of simulation YYYYMMDDHH[mmss]

#... email address where job messages should be send to
EMAIL_ADDRESS=burkhardt.rockel\@hzg.de     # your email address

#... project account (needed at DKRZ)
PROJECT_ACCOUNT=$(cat $HOME/.acct) # replace this with your project account

#... time increment of a CCLM partial job
INC_DATE=01:00:00      # MM:DD:HH  time increment for the CCLM job
                       # (the other parts of the chain are always monthly)
                       # valid values are 01:00:00, 00:01:00, 00:02:00, ... , 00:27:00

#... directory and binary path settings for utilities
UTILS_BINDIR=${SPDIR}/src/cfu/bin          # absolute path to directory of utility binaries
#... adopt the following to you computer system and check once in a while whether it is still the up-to-date version
CDO=?{initCDO}      # absolute path of the CDO binary 
NCO_BINDIR=?{initNCO_BINDIR}   # absolute path to directory of NCO binaries
NC_BINDIR=?{initNC_BINDIR} #  absolute path of the netcdf binaries (ncdump, nccopy)

#... int2lm job settings
#... choose whether to run int2lm (=1) or use already existing int2lm output (=0)
ITYPE_INT2LM=1

#... choose compression type of output in post-processing and archiving
#...    0 = no compression
#...    1 = internal compression (compression in netCDF file, requires netCDF Library with HDF-lib and z-lib)
#...    2 = external compression (compression with gzip, requires gzip to be installed)
ITYPE_COMPRESS_POST=0
ITYPE_COMPRESS_ARCH=0

#... choose SAMOA check (will be ignored, if SAMOA extension is not installed)
#...    0 = no SAMOA check
#...    1 = short SAMOA check (just the output of the last day of the month in each "outNN" directory)
#...    2 = long SAMOA check (all output files will be checked)
ITYPE_SAMOA=1

#... set number of boundary lines to be cut off in the time series data and before evaluating the data with SAMOA
NBOUNDCUT=10
