Introduction
The HPDA terrabyte compute infrastructure provides two clusters optimized for different use cases. The CPU cluster offers a large amount of cores for precise, flexible and fast parallel processing and can be used for a wide range of tasks. The GPU cluster is optimized for ultra-fast processing of large amounts of data and is especially suited for machine learning tasks. Both clusters are hosted at the LRZ (Leibniz Supercomputing Centre) in Garching near Munich.
