Platform for Scientific Computing

The Platform for Scientific Computing (Plattform für Wissenschaftliches Rechnen) is an interdisciplinary effort of professors from several disciplines and departments at the Bonn-Rhein-Sieg University to foster research and application on High Performance Computing (HPC). Main application areas are: Participating professors are:


The existing HPC hardware has several components each suitable for different computational demands. The main hardware ressources are, with a total of approx. 10,500 hardware threads, approx. 200,000 GPU-cores, an accumulated main memory size of approx. 23.5 TB, and an accumulated disk space of approx. 8505 TB (gross): Nodes are connected with 200 Gb/s Infiniband, 100 Gb/s Omni-Path and/or 1/10Gb-Ethernet. A detailed description of the hardware configuration can be found here. Some pictures can be found here.


The front-end node is the only external visible access point and can be accessed through The nodes can be used with parallel programs that are either based on a shared memory programming model (e.g. OpenMP) using up to 256-way parallelism, based on a GPU programming model (CUDA, OpenCL, OpenACC) using up to approx. 30,000 GPU cores in a system, or the cluster computer can be used in a distributed memory model (e.g. MPI) using all cluster nodes with up to approx. 10,000-way parallelism.

A detailled descriptions on how to use the cluster and information on the software configuration can be found here .
