+ZIH operates high performance computing (HPC) systems with more than 100.000 cores, 1000 GPUs, and a
+flexible storage hierarchy with about 40 PB total capacity. The HPC system provides an optimal
 research environment especially in the area of data analytics, artificial intelligence methods and
 machine learning as well as for processing extremely large data sets. Moreover it is also a perfect
 platform for highly scalable, data-intensive and compute-intensive applications and has extensive
