SPE·ED models are software-oriented. It models any type of software from novel applications to system software. It models distributed systems as well as mainframe execution environments. It models software written in any language running on any type of hardware and operating systems.
Users create and evaluate models with the following steps:
In order to automate the system model steps and enhance the visual perception of results, the computer facility models are deliberately simplified views of the system execution environment. It is not necessary to represent intricate processing details of the execution environment to study high level software tradeoffs.
Computer resource overhead specifications facilitate the analysis. This strategy for separating them from the software specification makes the models adaptable to all software, hardware, and mixed vendor environments. It also allows users to evaluate the performance of the software in various hardware environments to select the most appropriate platforms.
The overhead specifications are provided by a performance specialist, are stored in SPE·EDs database, and re-used in all models that execute in that environment.
For more information on how SPE·ED works, you can examine the Quick Start chapter of the User Guide (pdf).
