HPC Cluster Overview

The HPC cluster, located at the Carl von Ossietzsky Universität Oldenburg, consists of two clusters named CARL and EDDY. They are connected via FDR Infiniband for parallel computations and parallel I/O. CARL uses a 8:1 blocking network topology and EDDY uses a fully non-blocking network topology. Further, they are connected via an ethernet network for management and IPMI. They also share an GPFS parallel file system with about 900TB net capacity and 17/12 GB/s paralell read/write performance. Additional storage is provided by the central NAS-system of the IT-services.
