Build rundeck and compile

E1oM20

cd ~/projects/GISS/modelE_2.1_branch/decks

RUNNAME=E1oM20_r01

make rundeck RUN=${RUNNAME} RUNSRC=E1oM20 OVERWRITE=YES

cd ~/projects/GISS/modelE_2.1_branch/decks

RUNNAME=E213tlF40oQ40X1

# copy from docs folder. Not in template folder.
# make rundeck RUN=${RUNNAME} RUNSRC=E213F40oQ40 OVERWRITE=YES

 # YEARI=7501,MONTHI=1,DATEI=1,HOURI=0, ! pick IYEAR1=YEARI (default) or < YEARI

First run

Run 1 hour

../exec/runE ${RUNNAME} -cold-restart -np 2

Run longer until {YEAR,MONTH,DATE,HOUR}E defined in I

../exec/runE ${RUNNAME} -np 2

Examine outputs in run folder…

Postprocess

• From decks folder

cd ${RUNNAME}/

mkdir post
cd post
