Remote Execution

Distributed Structure

Efficient remote execution is possible because STM has a distributed structure. Figure
4-10 shows how the parts of STM are distributed between the UI mac
hine and the UUT.

Figure 4-10 Diagram of STM's Distributed Structure

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.
