The mission of the Visualization (VIS) department of HLRS is to support engineers and scientists in the visual analysis of data typically produced by simulations on high performance computers. The increasing complexity of simulation models and size of datasets resulted in longer analysis times. Instead users want to comprehend fast the meaning behind datasets and get insight into their simulation models. We provide visualization methods and technologies to reduce analysis time. Improved analysis possibilities are offered by immersing users into visual representations of their data and allowing them direct interaction with the data. An essential means for this is the integration of processing steps into a distributed software environment hiding heterogenuous hardware platforms.
