Testbeds and Benchmarking
The development of software components for high complex networked systems requires besides analytical and simulation-based evaluation methods more and more experiments in large real live environments. One method to build a new system on top of an existing system is to use virtualization. Virtualization of resources can be found in all areas of computing. Also in the domain of networking, virtualization is used to hide the characteristics of network resources (like routers, switches, etc.) from the way in which other systems interact with them. The PC˛ is engaged in investigating how virtualization can be utilized as a concept in the context of building new network testbeds.
The PC˛ benchmarking center is specialized in evaluating the performance of highspeed networks and parallel computer systems. Typically, these are based on cluster technology. Functional parts or complete systems are evaluated with the help of socalled low-, system-, and application-level benchmarks. Derived from this evaluation new system architectures will be developed. In addition, the PC˛ offers assistance in finding a high performance and cost efficient solution for parallel computers for already existing application programs and those which are under development.
