Dielectric elastomers (DEs) represent a new family of electromechanical transducers capable of undergoing large actuation stroke (>100%), allowing it to achieve performance that is not attainable with standard transduction technologies (e.g., piezo). Furthermore, DEs’ high flexibility permits us to design actuators with various shapes and sizes, allowing us to meet desired stroke or force specifications...
We discuss operational and organizational issues of an InfiniBand interconnection between two clusters over a distance of 28 km in day-to-day production use. We describe the setup of hardware and networking components, and the solution of technical integration problems. Then we present solutions for a federated authorization system for the cluster within our two participating universities and other...
This paper considers an InfiniBand connection between two bwGRiD clusters over a distance of 28 km in day-to-day production use. We discuss the hardware setup of InfiniBand messages converted and transported over a fiber optic connection. The two clusters can be operated as single system image, the batch system will enforce that all nodes for a job are allocated on one side of the cluster. This is...
