Abstract:   Our project will expand the scope of and merge existing structures for basic HPC programming and tuning support service at Technische Universität Darmstadt, Goethe-Universität Frankfurt, Johannes-Gutenberg-Universität Mainz, and Technische Universität Kaiserslautern. Together, these four sites provide not only a rich pool of challenging HPC applications emerging from first-class science, but also researchers dedicated to the advancement of HPC itself we can capitalize on. Thus, we want to deepen HPC service in areas where scientific expertise at these universities coincides with critical user needs, pushing expertise on GPU performance engineering, model-based scalability analysis, and algorithmic stability and reproducibility into performance engineering practices. The issue of GPU and vectorization performance is crucial, as it is relevant for many HPC architectures. Performance modeling is critical to identify potential performance bottlenecks before resources are expended unnecessarily, an issue that is essential for scaling applications, and, in particular, the efficient transition between tier-3, tier-2, and tier-1 computing centers. Lastly, algorithmic stability and reproducibility are becoming more and more important with respect to the credibility of HPC simulations. In this fashion, we will create a service organization that offers organizational and operational synergies for HPC users in our two states, exploiting the close spatial proximity of the sites involved. In addition, we will provide a model for merging basic on-site HPC support in a distributed organization with priority support for topics of relevance.
