Research Abstract

In the future energy system, large amounts of energy status data have to be collected from a geographically distributed set of sources. It is, however, often unclear how design decisions regarding the software and hardware system (e.g., the dimensioning of hardware resources, which processing middleware is used, or how often and in which granularity sensors provide data) influence the quality of the system (e.g., response time, cost or energy consumption). Trial-and-error is often not feasible because of availability requirements and costs. These decisions have to be made both when planning a system and when evolving the system. In the planning case, there often is no implementation or environment of the system which could be tested regarding the quality impact. In the evolution case, the change is often one that is not covered by historical data and can hence not be inferred using, say, a regression model. Both cases are supported using software quality models. Current modeling languages for this purpose are, however, often limited in their application to data-intensive software systems. They do not allow the explicit modeling of middleware components with quality impact (such as message queues or processing frameworks) and do not allow the description of data-dependent system behavior. In my thesis, the simulation of software performance for such systems is advanced. I will use the software architecture of a cluster that handles energy status data from an electronics packaging lab and of the planned Energy Lab 2.0 data processing infrastructure as two initial case studies. Based on these and from literature, I will derive recurring design questions and a suitable modeling language that includes data streams as first-class entities. The analysis of the resulting models is initially focused on performance. Other possible quality dimensions are for example the cost of the composed system, consistency guarantees made by messaging components or the reliability of the system.
