    Episode 03 - Terminology in ROMS

    prognostic equation—Any equation governing a system that contains a time derivative of a quantity and therefore can be used to determine the value of that quantity at a later time when the other terms in the equation are known (e.g., vorticity equation)

    diagnostic equation—Any equation governing a system that contains no time derivative and therefore specifies a balance of quantities in space at a moment of time (e.g., hydrostatic equation, balance equation)

    diagnostic variable —A quantity that is derived for the new timestep after the prognostic variables have been calculated, for example vertical wind speed. Further quantities are then computed via parameterizations

    (Note: for more information see http://www.java.com/en/download/help/5000010500.xml#selfextracting)

    2. Install Smartsvn
    Smartsvn can be used as soon as it is unpacked, so choose an appropriate directory before you start this program.
    Navigate to http://www.syntevo.com/smartsvn/download.jsp and download Generic (Linux, Unix, OS/2)
    # gunzip smartsvn-generic-2_1_8.tar.gz
    # tar –xvf smartsvn-generic-2_1_8.tar
    # cd smartsvn-2_1_8/bin
    # smartsvn.sh

    3. Install ifort (Intel® Fortran Compiler)
    Navigate to http://www.intel.com/cd/software/products/asmo-na/eng/compilers/282048.htm
    click “Free Non-commercial download” >“accept” > “Intel® Fortran Compiler Professional Edition for Linux”
    You need provide a valid email address, so that Intel Software Development can send you the serial number and *.lic file (1st installation with serial number and 2nd needs *.lic)
    “Intel(R) Fortran Compiler for Linux” > Version “9.0” > “Full Product”>”download”
    # gunzip l_fc_c_9.0.033.tar.gz
    # tar –xvf l_fc_c_9.0.033.tar
    # cd l_fc_c_9.0.033
    # ./install.sh and follow the instructions to complete installation. You may need to choose a directory to install opt/intel/fc/9.0 and opt/intel/idb/9.0.
    Wherever you decide to create such a directory, please remember to add them to $PATH
    # gedit $HOME/.bash_profile
    Find “user specific environment and startup program”
    $PATH = /opt/intel/fc/9.0/bin: /opt/intel/idb/9.0/bin:$PATH
    This new $PATH will not be activated until you restart the PC

    4. Install Netcdf
    # wget http://www.unidata.ucar.edu/downloads/netcdf/ftp/netcdf.tar.gz
    # gunzip netcdf.tar.gz
    # tar –xvf netcdf.tar
    # cd netcdf-3.6.2
    # ./configure (if you are not root user, please specify a subdirectory you have write permission like ./configure –prefix=/home/yunli/user/local)
    # make check
    # make install
    (If you are not root user, please)
    # gedit $HOME/.bash_profile, and change “$PATH = :$PATH”

    5. Install make3.81 (if running ROMS-3.0)
    # wget ftp://ftp.gnu.org/gnu/make/make-3.81.tar.gz
    # gunzip make-3.81.tar.gz
    # tar –xvf make-3.81.tar

    Episode 01 - Linux Installation

     internet advertising *~.~*_*~.~*_*~.~*_*~.~*_*~.~*_*~.~*_*~.~*_*~.~*_*~.~*_*~.~*
              Recently, I started to run ROMS ~~~ I had to say:
              "really exhausted but happy job".ROMS was not as
              easy as I expected, so more effort is needed.

              I hope dear rookies will join me until we become
              expertized together...

    =====================
    Checklist of Preliminaries
    =====================
    1. Red Hat Linux 8.0 installation CD (3 pieces)
    2. XX software (allocate physical disks)
    3. Internet connection
    4. Red Hat Linux 8.0
      > 1.5 GB of free disk space                                                                    
      > 1.8 GB of free disk space (If choosing both the GNOME and KDE)
      > 32M RAM (Required)
      > 64M RAM (Recommended)
    ========================================
    Install Linux to my Laptop -- Founder Yihe S260
    ========================================
    1. Check requirement and hardware
      15G Free disk space
      256M RAM
      Intel Celeon
      Intel® 82852/82855 GM/GME (Vitally important for display configuration)

    2. Allocate disk space
       My laptop was once installed Windows XP sp2 as OS. I do not want to withdraw it temporarily, so my husband Sam helps me reallocate 15G D disk space with XXX software. Then we get logical allocation as:
       /etc
       /xxx
       /xxx

    3. Follow the instruction and install Linux, please remember to select all the necessary packages. For me, I will run ROMS, so the developing package and GCC kit are indispensable.

    4. Rebooting the computer is required for complete installation. But my video card is not automatically detected by the drivers included in Linux 8.0, so I fail to log into the system with GUI (Graphic User Interface). Get rid of this problem, follow the steps below,
    Plugin the internet cable and restart PC. Follow the prompt to log into root user, and then type the command lines one by one
       # wget http://downloadmirror.intel.com/8203/eng/i915Graphics.tar.gz Mydisk/dir   
       # gunzip Mydisk/dir/i915Graphics.tar.gz
       # tar –xvf  Mydisk/dir/i915Graphics.tar
       # cd Mydisk/dir/dripkg   
       # ./install.sh
       # startx
    (NOTE : http://downloadmirror.intel.com/8211/eng/dri-I915-v1.1-20041217.i386.rpm can be an alternative, but a little complicated)
