Running ADAS

First, we choose a DAS run to simulate. For a list of various runs

 $ ls ~dao_ops 

on NCCS discover. As an example, we choose the run 'e572p5_fp'.

1. Checkout and build the model:

Check with Joe Stassi for model tag and module name.

 $ cvs co -r GEOSadas-5_7_2_p5_m1 GEOSadas-5_7
 $ cd GEOSadas/src
 $ source g5_modules
 $ gmake install

Or, one can checkout the corresponding AGCM model Fortuna-2_5_p6 (module Fortuna) and build it.

Note: For GEOSadas-5_7_2_p5_m1 in the example above, g5_modules will need to be edited in order to compile successfully on discover (due to SP1). You should change the discover section to be (where the bold items are changes, and mod5 is removed):

  set basedir = /discover/nobackup/projects/gmao/share/gmao_ops/Baselibs/v3.2.0_buildSLES11SP1
  set mod1 = comp/intel-11.0.083
  set mod2 = mpi/impi-3.2.2.006
  set mod3 = lib/mkl-10.0.3.020
  set mod4 = other/SIVO-PyD/spd_1.6.0_gcc-4.3.4-sp1
  
  set mods = ( $mod1 $mod2 $mod3 $mod4 )
  set modinit = /usr/share/modules/init/csh
  set loadmodules = 0 

2. Experiment setup:

To simulate a forecast run we can use gcm_setup to setup our experiment (instead of fvsetup). Run ./gcm_setup and provide the required answers

 $ cd Applications/GEOSgcm_App/
 $ ./gcm_setup

Cubed-sphere was not fully implemented in this model. Choose Lat/Lon with resolution 1152x721x72 for the 'e'-run. The other options are

 GOCART: yes
 GOCART Emission Files to use: OPS
 AERO_PROVIDER: GOCART
 HISTORY: Current

3. AGCM.rc, CAP.rc, HISTORY.rc

Edit these files to match with the corresponding .tmpl files in

 ~dao_ops/e572p5_fp/run

4. gcm_run.j

Ensure that the correct boundary datasets are linked to. Compare the links in this file to that of

 ~dao_ops/e572p5_fp/run/lnbcs

Also, be sure to add an "exit" after you run the executable (if, say, you want to run one segment).

If you are running the test via qsub, you'll also want to change the select line of gcm_run.j to:

#PBS -l select=90:ncpus=8:proc=west:mpiprocs=8

5. RC files

Copy the .rc files over

 $ find ~dao_ops/e572p5_fp/run -name "*.rc" -exec cp {} /path/to/home/dir/RC \;

6. restart files

Locate the dir containing restarts by querying FVARCH in FVDAS_Run_Config

 $ grep ATAG ~dao_ops/e572p5_fp/run/FVDAS_Run_Config

   setenv ATAG    GEOSadas-5_7_2_p5_m1
   setenv ATAG    $GTAG
   setenv FVARCH   /archive/u/gmao_ops/GEOS-5.7.2/${ATAG}/ #include trailing colon

Pick a date and time: say 2012/05/15, 21z

 $ cd /archive/u/gmao_ops/GEOS-5.7.2/GEOSadas-5_7_2_p5_m1/e572p5_fp/rs/Y2012/M05
 $ ls *_rst.20120515_21z.bin

Copy these files over from ARCHIVE to experiment directory and the rename them:

 $ cd /path/to/experiment
 $ rename _rst.20120515_21z.bin _rst *_rst.20120515_21z.bin
 $ rename e572p5_fp.  *rst

7. Run job

 $ qsub gcm_run.j
