A
developer uses BGML to model the software system and PSA-specific
evaluation activities. Specifically, the models are visually composed
via the Generic Modeling Environment (GME) model-driven toolsuite
(www.isis.vanderbilt.edu/Projects/gme/). The resulting models
detail the system's configuration options and inter-option constraints
and capture PSA-specific information, such as the metrics calculated
in a benchmarking experiment, the number and execution frequency of
low-level profiling probes, or event patterns to monitor for or filter
out of system logging server. For example, in the mission computing
scenario, we use a three component BasicSP scenario that
receives global position updates from a GPS device and displays them
at a GUI display in real-time.
