    NAME
         share_tree - Sun Grid Engine share tree file format

    DESCRIPTION
         The share tree defines the long-term  resource  entitlements
         of  users/projects  and  of  a hierarchy of arbitrary groups
         thereof.

         The current share tree can be  displayed  via  the  qconf(1)
         -sstree  option.  The  output  follows the share_tree format
         description. A share tree can be created and an existing can
         be modified via the -astree and -mstree options to qconf(1).
         The -sst option shows a formated  share  tree  (tree  view).
         Individual  share  tree  nodes  can  be  created,  modified,
         deleted, or shown via the -astnode, -dstnode, -mstnode,  and
         -sstnode options to qconf(1).

         Note, Sun Grid Engine allows  backslashes  (\)  be  used  to
         escape  newline (\newline) characters. The backslash and the
         newline are replaced with a space (" ") character before any
         interpretation.

    FORMAT
         The format of a share tree file is defined as follows:

         o  A new node starts with the attribute id, and  equal  sign
            and  the  numeric  identification  number  of  the  node.
            Further attributes of that node follow until another  id-
            keyword is encountered.

         o  The attribute type defines, if a  sharetree  node  refer-
            ences a user (type=0), or a project (type=1)

         o  The attribute childnodes contains a comma separated  list
            of child nodes to this node.

         o  The parameter name refers to an arbitrary  name  for  the
            node  or to a corresponding user (see user(5)) or project
            (see project(5)) if the node is a leaf node of the  share
            tree. The name for the root node of the tree is "Root" by
            convention.

         o  The parameter shares defines the share of the node  among
            the nodes with the same parent node.

         o  A user leaf node named 'default' can be defined as a des-
            cendant  of  a  project(5))  node  in the share tree. The
            default node defines the number of shares for users   who
            are  running  in  the project, but who do not have a user
            node defined under the project. The default user node  is
            a  convenient  way  of  specifying  a single node for all
            users which should receive an equal share of the  project
            resources. The default node may be specified by itself or
            with other user(5)) nodes at the same level below a  pro-
            ject.  All  users, whether explicitly specified as a user
            node or those which map to the 'default' user  node  must
            have  a corresponding user(5)) object defined in order to
            get shares. Do not  configure  a  user(5))  object  named
            'default'.

    EXAMPLES
         Jobs of projects P1 and P2 get 50 shares, all other jobs get
         10 shares.
