Abstract:   Data centers often face similar challenges when supporting analysis and optimization of relevant applications. From the user perspective, the benefit of performance engineering is difficult to quantify and so are the costs involved in this tuning/optimization. Existing codes and workflows must often be adjusted in non-trivial ways to explore the benefits of novel concepts and emerging technologies, which often causes users to hesitate. It is important to better understand these cost drivers in order to ultimately increase the scientific output of data centers. The German state of Hamburg has three data centers, each independently providing compute power and support to their users. Two general purpose data centers are responsible for the needs of Universität Hamburg and Technische Universität Hamburg, respectively. The third data center is a Tier-2 center supporting climate research. Although near to each other, the collaboration of support staff between the data centers has been limited. As part of the project, this collaboration will be strengthened.
