Graphical Display of System Use

(Contributed by William Gropp and Ewing Lusk)

We have written a tool, xsp1info, that displays the usage of the SP1 when using the EUIH message-passing system. This tool, written using tcl and tk, displays

• the partitions in use. Each partition is displayed in a different color.
• a list of partitions, containing the username, size, and amount of time the partition has been in use.

An example display is shown in Figure .

In addition, each node is represented by a button. Pushing this button with the mouse can bring up an xterm on that node or show the load average (depending on which mouse button is used). The display also shows the number of the node the mouse is pointing to and the time when the display was last updated.

Using xsp1info, users can see how much of the machine is in use with EUIH jobs and see where their EUIH jobs are running. It also provides a convenient way to open xterms on the SP1.
