Remote Execution
In remote execution, you can run STM as a client server application. The user interface module
and the support tools module are on separate systems. The user interface module is located on the
control system, and the support tools module is located on the system under test. Figure 1-4 illustrates
the remote execution architecture.

Multiple System Execution
In multiple system execution, you can use STM to diagnose multiple systems at the same time. You
can access several systems under test using a single control system, or access a single system under
test using several control systems. Figure 1-5 illustrates the two types of architecture.
