Next-Generation HPC System @ HLRS
Hawk is the flagship supercomputer of the High-Performance Computing Center Stuttgart (HLRS). At time of installation, it among the fastest high-performance computers in the world and the fastest general-purpose machine for industrial production in Europe.
Designed with the needs of HLRS's users in mind, Hawk is optimized for engineering simulation applications. In concert with our other platforms for high-performance data analytics and artificial intelligence, Hawk enables HLRS to support new kinds of workflows that combine data generation, simulation, big data analysis, deep learning, and other data science methods.
