How to run RSM on imtf4
As of 2010/8/2
by Kei Yoshimura (AORI)
Using Cygwin in your laptop
• Double click “cygwin”
• run “startx”
• from any terminal, login to imtf4 machine
$ ssh –Y rsm1@imtf4.ees.hokudai.ac.jp
rsm1~rsm6 are available depends on traffic.
password: rsm10sapporo
• Try “grads” to check X-window works.
“@” symbol is located right-hand side of your keyboard
(next to “P”)!!
Cygwin’s window size problem
• Please change your terminal window size by
– click and hold the up-right corner of the terminal.
– once drag your mouse outside of terminal
– drag back into the terminal
– adjust terminal size
• Create your directory on your home directory,
such as
– mkdir /work1/RSM/[your name]
– cd /work1/RSM/[your name]
Preparation for installation
• log-in imtf4
$ ssh –Y rsm1@imtf4.ees.hokudai.ac.jp
rsm1~rsm6 are available with password rsm10sapporo
Technical Notes
• Use /work1/RSM/[your_name] directory instead of
/home directory. Then delete your directory in
/home. (please do not delete other’s!)
• Select 2 for number of pes.
• You may use your computer in your institute instead
of imtf4. In this case, You need
– either intel or pgi fortran
– mpich program if you want to MPI
– CVSROOT=:pserver:anoncvs@rokka.ucsd.edu:/rokka1/ka
na/cvs-server-root/cpscvs
(see http://g-rsm.wikispaces.com/Installation)
Typical Troubleshoot
• Compilation error:
– “cvs co” doesn’t work!  set CVSROOT correctly
– compilation stops!  Ask assistants!
• Execution error:
– Finish too early!  check files in output directory (r_000).
You should have sig.ft48.
– Overflown (lots of “*” in out_rfcst files)!  shorten
DELTAT_REG in rsm/rsim files and rerun.
• Post-process error:
– grib2ctl.pl does not work!  copy /home/rsm1/grib2ctl.pl
to your working directory and try again.
Recompile without downloading
• If you have downloaded the necessary files, you
don’t need to do “./install” process.
• If you have problem in “libs”,
– cd libs
– configure-libs
– make (or make clean, make)
• If you have problem in “rsm”,
– cd rsm
– configure-model
– make (or make clean, make)
• If you want to create other executable script
– cd rsm_runs
– configure-scr XXXXX [rsim, rsm, etc.]
Preparation for installation 2
• Set CVSROOT environment
$ export CVSROOT=/work1/RSM/cpscvs
or
$ setenv CVSROOT /work1/RSM/cpscvs
!! without “=“
For your information:
• CVS: Concurrent Versions System
• The CVS in Hokudai is mirrored from Scripps,
California.
Installation through CVS
$ cd /work1/RSM/[your name] # go to working directory
$ mkdir test ; cd test # creating working directory
$ cvs co INSTALL
# needs to be all capital
$ ./install
choose followings
model: rsm
architecture: mpi
institution: ecpc
machine: linux
nickname: imtf4
compiler: intel
additional options: no
domain: 37 (81x87, Japan, 30km) -> you can choose any. b
ut smaller domain is recommended
time: 00:30 (just press enter)
# of pes: 2
script: rsm
Then compilation starts. This process may take 10-15 minutes.
Running RSM
• rsm runs in rsm_runs directory.
$ cd rsm_runs
$ ./rsm
– this script (rsm) runs a 48 hours simulation from
1990/3/9 0Z.
– check the calculation status by
$ top
or
$ tail –f r_000/out-rfcst.ft48
Calculation takes 10 minutes or so.
Visualize the results 1
• Let’s use GrADS.
$ cd r_000
$ ~/grib2ctl.pl r_pgb.ft00 > r_pgb.ctl
• Modify r_pgb.ctl as follows (shown by red):
dset ^r_pgb.ft%f2
index ^r_pgb.ft00.idx
options template
undef 9.999E+20
...
tdef 17 linear 00Z09mar1990 3hr
zdef 12 levels
...
then execute “gribmap”
$ gribmap –i r_pgb.ctl
Visualize the results 2
• Launch grads and open r_pgb.ctl
$ grads
> open r_pgb.ctl
• For example, you can see an animation of
500hPa level by
> set z 6
> set t 1 17
> d hgtprs
# set the height at 500hPa
# set the time from 1990/3/9 0Z to 3/11 0Z
# visualize the height

Changing the model domain
• You may choose domain from def/def_rsm
[kei@shui def]$ ls -1 def_rsm/
CVS
rsm1024x651_g62k28_usa_10km_merc
rsm1024x669_g62k28_usa_10km_merc
rsm108x109_g62k28_california_5km_merc
...
• modify rsm/configure-model and compile
again.
$ cd rsm
edit MODEL_DEFINE in configure-model
$ ./configure-model
$ make clean ; make
$ cd ../rsm_runs
$ configure-scr rsm
Changing simulation period
• Use rsim script in rsm_runs directory
$ cd rsm_runs
$ ./configure-scr rsim
edit year, date, time, as you like.
$ ./rsim
