Reconfigurable parallel computing

Summary form only given. The dynamic reconfiguration of hardware stands for the change of hardware while the system is operating. Its benefit is the adaption to different computing requirements. For instance, an improved use of communication networks can be achieved: Many networks reveal the characteristic that connections between specific communication partners show a smaller latency than others. These localities (connections with a small latency) can be used for those communication partners who communicate heavily with each other. If several applications run in parallel on the system and a part of applications change, this can implicate that after the change, new partners with heavy communication cannot use a connection of small latency. Then, a dynamic reconfiguration of the network can help.
