Research Interest

Stuttgart Research Centre for Simulation Technologie and Cluster of Excellence "Simulation Technology (SimTech)"

Working Area of IAAS	In "SimTech", the IAAS is working on the creation of a workflow management system (WfMS) for modeling and executing simulation workflows. The WfMS will be especially tailored to requirements of scientists. The underlying technical complexity ought to be hidden for scientists to enable them to concentrate on their core competencies. We want to achieve this aim with three tightly coupled projects, each of which dealing with a partial aspect of the WfMS: Modelling of Simulation Workflows Runtime for Simulation Workflows Flexibility of Simulation Workflows
Project "Flexibility of Simulation Workflows"	Usually, simulation workflows are exposed to frequent changes: the underlying infrastructure is often highly dynamic (e.g. the insertion of additional processors), simulations need to be adapted during execution (e.g. the modification of parameters, the insertion of additional steps). In this project I am therefore concerned with flexibility of simulation workflows. This especially comprises avoidance of changes of workflows as well as the adaptation of workflows at runtime. Consequently, flexibility has an impact on both buildtime and runtime of workflows. Within this project requirements of scientists with respect to flexibility are gathered, classified, assessed, and implemented. Moreover, a monitoring tool will be developed that will enable scientists to intuitively modify running simulations to satisfy the "trial-and-error" approach they follow when doing their work.
Challenges	Compensation in modified simulations Validation of adapted workflows Persistent storage of the execution history of modified simulations Persistent storage of changes on workflows Execution of workflow fragments (i.e. incompletely modeled workflows) Repeated execution of activities Enforcement of paths Hiding of the technical details of underlying adaptability and deployment mechanisms
