You can run the STM user interface on one machine, and use it to run support tools on one or more remote machines. See Figure 7-7 "Possible UI and UUT Connections" for a display of possible connections.

The computer running the user interface is the UI system and the computer running the support tools is the Unit Under Test or UUT).

As always you can run the user interface and support tools on the same machine. In this case the UI machine and the UUT are one and the same.

Distributed Structure

Efficient remote execution is possible because STM has a distributed structure. Figure 7-8 "Diagram of STM's Distributed Structure" shows how the parts of STM are distributed between the UI machine and the UUT. (This diagram also shows xstm, which is only available on HP-UX.)

The UI system contains the binaries for the graphical, menu, and command line interfaces, as well as for the Core UI which underlies them. The UI also contains the text to be displayed (message catalogs and help volumes).

The Unit Under Test (UUT) contains the binaries for the support tools (Diagnose, FW Update, Exercise, Expert, etc.) and the libraries which support them.

Improving Performance

This distributed design makes for good performance. This is because data and code reside on the machine that makes use of them. The UI system has code for the UI, and message text for both the UI and support tools. The UUT system has the support tool executables. Little text is passed between the two machines, usually only the information required to locate a message.
