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)) that serve
name spaces using 9P. (See intro(5) for a description of
the protocol.) The top level displays the type of resource,
for instance '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-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.
