	abstract	 = {Evaluating systems and optimizing applications in high-performance computing (HPC) is a tedious task. Trace files, which are already commonly used to analyse and tune applications, also serve as a good approximation to reproduce workloads of scientific applications. The thesis presents design considerations and discusses a prototype implementation for a flexible tool to mimic the behavior of parallel applications by replaying trace files. In the end it is shown that a plugin based replay engine is able to replay parallel workloads that use MPI and POSIX I/O. It is further demonstrated how automatic trace manipulation in combination with the replay engine allows to be used as a virtual lab.},
