GRID-SESSION(1)                                   GRID-SESSION(1)

     NAME
          grid: session - graphical interface for configuring tasks
          using grid-cpu(4) and grid-ns(1) resources

     SYNOPSIS
          grid/session

     DESCRIPTION
          Session allows the user to build up a single namespace from
          various different namespace resources and configure a set of
          commands to be executed within this namespace. The execution
          then takes place on one or more selected grid-cpu(4)
          resources.

          Once started, session presents a heirarchical view of cur-
          rently registered resources (such as grid-ns(1)) which
          export a Styx (see intro(5)) namespace. The top level dis-
          plays the type of resource e.g. 'CPUresource', whilst the
          second level shows the name of each individual resource.
          Descending futher down the tree will reveal the attributes
          of the selected resource. To mount a resource and see the
          namespace it exports, click mouse button 3 on the resource
          name. The view will switch to a split pane view displaying
          the resource namespace with directories listed on the left
          and all files in the current directory displayed on the
          right.

          Clicking mouse button 3 on a file or directory will cause it
          to be added to the command or namespace list at the bottom
          of the window. Mouse button 3 is again used on items in
          either of these lists to display a menu containing the name
          of the resource on which they are located as well as the
          option to remove them. The Cmd and Ns buttons located at the
          top of the window toggle the view between the selected com-
          mands and the selected namespace. The Resources button
          returns to the initial view containing the currently regis-
          tered resources and Refresh updates the list in case any
          resources have been added or removed.

        The Command List
          This contains a list of all commands to be executed. Any
          arguments may be entered by clicking on the gap after args:
          and typing into the box. Commands will be executed in order
          from top (first) to bottom (last).

        The Namespace List
          This contains a list of all the directories to be imported
          in order to create the local namespace of the selected

     GRID-SESSION(1)                                   GRID-SESSION(1)

          grid-cpu(4) resource(s). By default, several directories
          will be imported from the local machine. To select these,
          click button 3 on import local namespace and (un)check the
          directories as required. To toggle this option on and off,
          click button 1 on import local namespace. These default
          directories are required by many commands for normal execu-
          tion so it is recommended that they are not disabled unless
          they are definitely not needed. Importing a directory of the
          same name as one of the default directories will automati-
          cally overwrite the default. Therefore, it is not necessary
          to disable a default directory if the same name is to be
          imported from elsewhere.

          A given directory can only be imported once so it is not
          possible, for example, to import /usr/inferno from two dif-
          ferent machines.  Session will automatically import the
          directories containing each of the selected commands but any
          others required must be explicitly imported. For example: If
          one of the commands is:

               /usr/inferno/runme.dis -f /appl/lib

          Session will import /usr/inferno/ but /appl/lib would have
          to be specified in the namespace list.

        Execution
          Once the command and namespace lists have been configured,
          click Ok on the Session window. This will bring up the
          grid-query(1) window containing a list of the available
          grid-cpu(4) resources. To select one or more of these for
          execution, click on the name with button 3 and it will be
          added to the list. If a specific grid-cpu(4) resource is not
          required, click button 3 on CPU resource and select the num-
          ber you require by clicking on the number following the list
          entry and dragging the mouse up or down.

          Once the required grid-cpu(4) resources have been selected,
          click Ok and execution will commence.
