Installing G09W with Linda


1) Install the G09W+Linda from the distribution CD.  

2) Install Microsoft Windows Services for UNIX (SFU)

   a) Download from www.microsoft.com/windows/sfu.  Version 3.5 is the
      version tested with G09W+Linda.

   b) Run the self-extractor and change the directory to a temporary
      directory like c:\temp.

   c) Start the installation by running C:\temp\sfusetup.msi from the
      start menu or by double clicking on the icon.

   d) After identifying yourself and accepting the license agreement
      select the Custom installation and remove all options except
      Remote Connectivity.  Modify that option to install options on the
      hard disk.  Then select Local User Name Mapping with Password and
      group files.  Leave the password and group file names blank and
      accept the default Windows domain.  Finally select the location
      for the utilities, C:\SFU.

3) Create a .rhosts file. Enter
   edit c:\windows\system32\drivers\etc\.rhosts

   from the Start=>Run dialog or a command window.  Once in the editor,
   enter a line with the node name for each node to be used with
   G09W+Linda and a plus sign to allow any user to use G09W+Linda.
   Replace the plus sign with a list of users if only selected users are
   allowed to use G09W+Linda. For example:

       	Alpha1 charlie
       	Alpha2 +

   would allow user charlie on node Alpha1 and any user on node Alpha2
   to run Linda.

4) Use the Registry Editor (regedit) to change the value of the
   parameter:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RshSvc\DefaultTimeOut

   from 600 to 4294967 (double click on it to open an edit window).

   Then modify the value for:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\IRPStackSize

   If this parameter is not present, add it as a new DWord value: Right
   click on Parameters, then choose New=>DWORD Value. Set the name to
   IRPStackSize, then double click on it. Change the base to Decimal and
   set the value to 25.

   Close the Registry Editor and reboot the computer.

5) The SFU package uses the utility rshpswd.exe to store passwords.  It
   needs to be run on each node by each G09W+Linda user once.  If you
   installed SFU in the default location you can run

   c:\sfu\common\rshpswd.exe

   from the Start=>Run dialog or from Windows Explorer.  Once this is
   done test the installation with

   rsh node dir

   in a command window with node replaced by the name of your node.

6) If a firewall is enabled on your system, specify exceptions for
   TCP/IP Remote Shell Command and for cLindaLauncher.

7) Share the G09W directory for use over the network: right click on the
   folder and select Sharing and Security. Enable sharing by clicking on
   the corresponding radio button. Click on the Permissions button and
   verify that Everyone or Authenticated Users has Read access.  The
   ability to write files is not needed.

8) Start G09W and select File=>Preferences.  Change the Gaussian Bin
   Path to

   \\node\G09w

   or the proper UNC naming location for your G09W installation.  Also
   define the Linda parameters. Minimally, you need to specify the list
   of computers which will be used to for Linda runs, as in this
   example:

   -nodelist "Alpha1 Alpha2"

   The master node, where G09W starts, will be added by default but can
   be specified in this list.  Other Linda parameters can be found in
   the Linda documentation.

9) Repeat steps 2-6 on each worker computer system. G09W must be
   installed on each machine which will be used as a master node.

10) Test the installation by modifying an input file like
    G09w\tests\gjf\test397.gjf.  Add the line

    %lindaworkers=node1:n1,node2:n2

    where node1 is the name of the first computer and n1 is the number 
    of nodes to use on that computer. Likewise, node2 is the name of 
    the second computer and n2 is the number of nodes to use on that 
    computer. An example would look like this:

    %lindaworkers=Alpha1:1,Alpha2:2

    Use the Task Manager on each remote node to look for processes like
    l302.exl or l502.exl.  These processes will also be seen on the
    Master node when corresponding the standard link, l302.exe or
    l503.exe, is active.

Frequently Asked Questions

Q) I got the error "Unable to execute the command" when I run rsh beta3
   dir. What's wrong?

A) Check that you have run rshpswd for your account on node beta3.

Q) When I start G09W it does not show the Linda item on the Preferences,
   and it has the wrong Revision number on the header, Rev. A.1.  What's
   wrong?

A) Your G09w directory is not properly shared.  Make sure it is shared
   for network access.  Also double check that you typed the path for
   the G09w bin directory correctly in the G09W Preferences.
