CRC 1404/1: Distributed Run-Time Monitoring and Control of Data Analysis Workflows (SP B06)

Executions of DAWs are driven by specifications of the individual steps of a data-processing pipeline and the data it processes. However, for a multitude of reasons, execution may not function as desired, especially when distributed systems are used, which calls for proactive runtime monitoring of executions to detect and possibly resolve any problems early on. B06 will investigate the foundations of distributed monitoring and of control systems for DAWs, which is a prerequisite for the design of dependable DAWs. Cooperations will be established especially with A01, on the notion of “abnormal” versus “normal “behavior” of an execution, and with B03 regarding the monitoring of distributed executions. The subproject will be led by Prof. Grunske, an expert in automated software analysis for error detection, and Prof. Rabl, an expert in efficient distributed streaming engines.
