Short Description

The Doppler cluster is a massively parallel system consisting of over 3 dozen heterogeneous compute nodes and a high-performance interconnection network.
The compute nodes are continuously extended according to the requirements and can currently cover the following areas relevant for research and simulation:
1) symmetric multi-processing (SMP) with up to 64 cores per node
2) distributed computing (MPI)
3) mixed-mode (SMP + MPI)
4) GPU computing (512 to 3072 CUDA cores per GPU)
5) memory-intensive applications (128-1024 GB per system-image)
The resources of the cluster are used through a 'fair queuing' system (batch processing) by the participating partners, within the university or in the context of joint research projects also by external partners and sister institutions.
