-on NCCS discover. As an example, we choose the run <tt>d591_fpit</tt> (for more about GMAO products, please see https://gmao.gsfc.nasa.gov/products)

- $ grep ATAG ~dao_ops/d591_fpit/run/FVDAS_Run_Config
-  setenv ATAG    GEOSadas-5_9_1_p7
-This gives us the model tag.

+====FVHOME====
+FVHOME is the home directory for fvDAS experiment. Resource files, restarts and system output will be stored
+under this directory. Usually it contains subdiretories:
+ ana/        first guess/analysis output
+ anasa/      job script to run stand-alone analysis
+ daotovs/    daotovs field output
+ diag/       diagnostic field output
+ etc/        listings and other odds & ends
+ fcst/       forecast run directory
+ fvInput/    process required inputs
+ obs/        post-analysis ODS files
+ prog/       prognostic field output
+ recycle/    latest restart files
+ rs/         restart files
+ run/        resource files
-After saving these inputs, move to the experiment directory
+<tt>$FVHOME/.FVROOT</tt> gives the location of the installation <tt>bin</tt> directory.
- $ cd $NOBACKUP/g591p4_d72/run
-At this point, one can edit CAP.rc.tmpl to run 12-hour experiment. Also, one can turn on MAPL timers and memutils
+Some of these directories (<tt>ana/</tt>, <tt>chem/</tt>, <tt>diag/</tt>, <tt>etc/</tt>, <tt>obs/</tt>, <tt>rs/</tt>) are stored in the archive. After completing the experiment, look in <tt>$ARCHIVE/g591p8</tt> (where <tt>g591p8</tt> is the experiment ID).
- JOB_SGMT:     0 120000
+====Run directory====
- NUM_SGMT:     1
+  $ cd $FVHOME/run
- MAPL_ENABLE_TIMERS: YES
-  MAPL_ENABLE_MEMUTILS: YES
-To run one segment each of <tt>GSIsa.x</tt> and <tt>GEOSgcm.x</tt> add '<tt>exit</tt>' before 'PART IV - Next PBS Job Segment' in <tt>g5das.j</tt>.
+<tt>g5das.j</tt> is the job submission script. The number of cpus etc. can be changed here (if they haven't already been changed during setup). Also, if you want to run a single cycle of <tt>GSIsa.x</tt> & <tt>GEOSgcm.x</tt> add <tt>exit</tt> right before 'PART IV'.
+<!--
+To simulate the OPS run d591_fpit, we make a few changes:
+# NX, NY in AGCM.rc.tmpl and AGCM.BOOTSTRAP.rc.tmpl have the same values (8, 48) as in the OPS run
+# Copy HISTORY.rc.tmpl over from the OPS run
+# Copy obsys.rc over from the OPT run
+# NX, NY in GSI_GridComp.rc.tmpl should match those from the OPS run (6, 36)
+# Set NUM_SGMT to 1 in CAP.rc.tmpl
+# <tt>g5das.j</tt>
+## PBS -l select=32
+## <tt>setenv NCPUS     384</tt>
+## <tt>setenv NCPUS_GSI 216</tt>
+## '''One cycle''': To run one segment each of GSIsa.x and GEOSgcm.x add '<tt>exit</tt>' before 'PART IV'

-====Data Assimilation experiment====
+===Data Assimilation===
-  $ cd $NOBACKUP/g591p4_d72/run
+  $ cd $FVHOME/run
   $ qsub g5das.j
 <tt>g5das</tt> creates a scratch directory <tt>$NOBACKUP/fvwork.xxxx</tt> and runs the experiment there. After the initial setup, <tt>GSIsa.x</tt> is run with output written to <tt>ana.log</tt> followed by <tt>GEOSgcm.x</tt> which writes its output to <tt>stdout</tt> and <tt>fvpsas.log</tt>.
