An overview of the data visualization options that are available from SURF, including usage of Snellius and other infrastructure, plus available support from SURF for visualization projects.


This presentation will touch upon a few technical topics such as remote visualization, OpenOnDemand and GPU usage. We will also talk about a few non-technical things such as high-level workflows, support and courses. Finally, we show some visualization examples.
