G-RSM CVS System at
ECPC

Oceanography
Installation



Install CVS (http://www.nongnu.org/cvs/)
C and Fortran compilers required (we usually
use portland group compilers on Linux
machines but Intel should work too)
Set environmental variable CVSROOT (e.g.
setenv CVSROOT :pserver:[email protected]:
/rokka1/kana/cvs-server-root/cpscvs
Installation

$ cvs co Install [Note Capital “I”]
You will get “inst” and “install” scripts. “inst” is a
wrapper script that calls “install”
./inst [model version] [topography option]
[model version] rsm_frozen, rsm_latest, crsm_frozen,
gsm_frozen, gsm_latest, scm_latest
[topography option] hi (use 30 seconds gtopo30
topography) or lo (use 4minutes topography)
Installation
Installer will ask you:
 Which model [rsm/gsm/crsm/scm]
 Machine architecture [single/thread/mpi/hybrid]
 Institution [ecpc/sdsc/ncar, etc] choose ecpc if not
available
 Machine name [ibmsp/dec/cray/intel/linux, etc]
 Model resolution [e.g. T62L28 r54x55, T62L28
r8167c5487] you have to create resolution definition files
in rsm/def if you want to define your own domain
 Which script [rsm/rsim/csim, etc] rsm is for testing
purpose (48hours integration). rsim is for downscaling
with global files. csim is for crsm (c2r).

You can choose to use “install” script.
./install --model=[rsm/gsm/crsm/scm] --version=[…] --enable[numerous options]
--enable-osu2
--enable-noah
--enable-cldw-zc : Zhao-Carr cloud water scheme
--enable-cldw-sy3n: Song-You Hong cloud water scheme
--enable-cldw-sy5
--enable-cldw-sy6
--enable-sas: SAS
--enable-ccmcnv: NCAR CCM3 Zhang McFarlane convection
--enable-baseout: post processed basefield output (r_bpgb.ftxx)
CVS system

cvs co [module_name]
cvs update [file_name]
cvs diff [file_name]
cvs log [file_name]
You can use options such as –r (version), date
Model System

libs : library, utilities, independent of model
resolution but machine dependent

rsm (or crsm): source codes and binaries, model
resolution dependent
e.g., rsm/def/rsm6228r5455

runs: run scripts
runs/runscr: run scripts called by rsm/rsim/csim
runs/expscr: templates for rsm/rsim/csim
Building the model without
installer



In libs, $ configure-libs
In rsm
You can edit rsm/def/physics.h, misc.h,
debug.h, diag.h to change model options
such as KF2 (Kain Fritsch convection) that is
not supported by --enable-xxx with installer
script.
$ configure-model
In runs, $ configure-scr [rsm/rsim/csim]
Other things to note…

Set stacksize to unlimited, otherwise rmtn.x
fails.
Regional Domain


rsm/def/rsm6228r5455
igrd, jgrd, cigrd, cjgrd
Igrd has to be a product of integer powers of 2, 3, and 5. On
IBM, integer power for 3 cannot be more than 2. jgrd has to
be an odd number. cigrd and jgrd are coarse resolution
regional file paramters for crsm.


Parameters
RPROJ, RTRUTH, RORIENT, RDELX, RDELY,
RCENLAT, RCENLON, RLFTGRD, RBTMGRD
Use libs/etc/prmap to choose a domain.
Utility Programs in libs/etc


date: returns date of sigma and surface files
fhour:
force_date_grib: change the date in grib files (r_pgb.ftxx)
grmap: creates ctl file for GrADS from r_pgb.ftxx
grmean: creates average of r_pgb.ftxx
incdte:
inchour:
jd: returns julian day from
prmap: used for choosing the domain. reads igrd and jgrd in
rsm/define.h and domain paramters in rsm/rsim script and
creates prmap.ctl which is opened in GrADs for display.
Input Files (for RSM)

Available global files from the data server at ECPC
6-hourly R1 (NCEP/NCAR Reanalysis): r1/ directory
6-hourly R2 (NCEP/DOE Reanalysis): r2/ directory
daily sst.grib: sfcanl/ directory
daily ice.grib: sfcanl/ directory
