First step memo for GSM simulation †

  • For simulations on COMPAS, please see here

Customized Installation †

In gsm

  1. Modify source codes (in gsm/src/)
  2. Modify gsm/opt/options-[machine]-[arch] for your environment.
  3. execute "configure-model"
  4. execute "make"
↑

Current problems †

See common Q&A.

Download, Installation, ant Test Run †

$ setenv CVSROOT :pserver:anoncvs@rokka.ucsd.edu:/rokka1/kana/cvs-server-root/cpscvs
$ mkdir GSM ; cd GSM (for example)
$ cvs co Install
$ ./inst gsm_latest lo   (-> it takes few minutes. Select "single" for arch)
 "gsm_latest" is changeable. For test run, following works.
 $ ./install --model=gsm --date=20061218 lo
$ limit stacksize unlimited
$ cd gruns
$ ./gsm (-> it will make g_000 directory and output)

It takes 12 minutes for 72 hours run by fuyu (one Xeon 3.2G). 
Check g_000 directory and output files.
↑

Visualization †

$ cd g_000 (from $GSMDIR/gruns)
$ ../../libs/etc/grmap -g0 pgb.ft00
 --> pgb.ft00.idx and pgb.ft00.ctl are made.
$ grads

Other way (more useful!)

$ cd g_000
$ ../../libs/etc/grmap -g0 pgb.ft00
 -> Make template ctl file.
$ mv pgb.ft00.ctl pgb.ft.ctl
$ vi pgb.ft.ctl
 Edit option lines as below
  dset /home/kyoshimura/GSMmpi/gruns/g_004/pgb.ft%f2 
  options template yrev
  index /home/kyoshimura/GSMmpi/gruns/g_004/pgb.ft.idx
  tdef    7 linear              00Z9MAR1990     24hr
$ gribmap -i pgb.ft.ctl
 -> pgb.ft.idx created.
$ grads
↑

MPI run †

Verified by fuyu. Takes 5 minutes for 72 hours run by 4-cpu.
  1. Installation of mpich (See here) 
    For making it easier, should be installed in "/usr/local/mpich" (-> but you can configure it).
  2. Technical tips of gsm-installation.
    1. Similar setup as test run, but select "mpi" for arch.
    2. If the installation stops, try below 
      1. Change MPICH_DIR in gsm/configure-model 
   (<- when mpich is not installed in /usr/local/mpich)
2. Delete "-lgm" in EXTRA_LIBS in gsm/opt/options-linux-mpi
    3. Make in gsm directory. 
      $ cd gsm
$ make

Reading GSM script †

#!/bin/sh 
#
set -ax
#
# this script makes 72 hour integration starting from an example initial
# condition. ideal for first testing the system on new computer system
#
# ---------------  user changeable parameters ------------------------
#
# Change the following variable if you are running separate experiments
# from the same directory
#
RUNNAME=g_004

Set your runname. Its directory will be created in gruns/.

#
# Intervals of sfc execution, sigma output, sfc output and flx output
# Various options for running the model
#
ENDHOUR=144

End time of calculation.

INCHOUR=$ENDHOUR
INTSFCX=48

Don't know

INTSIG=24
INTSFC=24

writing out sig.ftXX and sfc.ftXX files in this interval. "0" is equal to "1". If comment out, equal to INTPOST.

INTPOST=24

making pgb.ftXX and flx.ftXX files in this interval.

INTRESTART=12
#
FCST_RESTART=yes

Rewriting "sigit" and "sfci" in this interval

#
#  ------------- below for expert user only --------------------
#
# If you wish, you may modify EXECDIR to /tmp directory and keep these
# scripts on your permanent disk.
#
EXECDIR=/home/kyoshimura/GSMmpi/gruns/$RUNNAME
#
# -------  do not change below  -------------------------------------
#
mkdir -p $EXECDIR 2>/dev/null

Creating working directory

#
INITIAL_SIGMA=/home/kyoshimura/GSMmpi/libs/con/sigft0090030900.asc

INITIAL_SFC=/home/kyoshimura/GSMmpi/libs/con/sfcanl90030900.asc
INITIAL_SFC_FILE_TYPE=osu1

Same as sigma-level data, but for surface.
