Abstract: Abstract HLRS, the High Performance Computing Center in Stuttgart, runs one of the most powerful HPC systems in Europe. As HPC systems are expensive resources, one of the main objectives of HLRS is to maximize scientific profit and progress from their usage. In order to achieve this, HLRS wants to ensure an efficient utilization of the HPC resources and advises its users in order to do so. In addition, HLRS committed to improve its sustainability. For data centers, this can be done by optimizing the power consumption. Since performance optimization shortens computing time, it is in a sense transferable to saving energy. Also, in future computer architectures, performance optimization will no longer be achieved by new hardware. Performance bottleneck detection and performance optimization of codes and applications therefore is one of the key challenges in HPC.
