So, what is Society?
• And, you know, there is no such thing as society.
Margret Thatcher, October 31, 1987
• Sie ist eine Differenz. Sie ist nicht nur ein Objekt mit bestimmten
Qualitäten. Sie ist eine Differenz, die sie selber erzeugt, wobei auf
der einen Seite die innere Seite dieser Differenz, das heißt, das
was die Gesellschaft tut, wie sie operiert, wie sie beobachtet, wie
sie kommuniziert zu sehen ist, aber auf der andere Seite auch
noch etwas.
Niklas Luhmann, 1992

Society’s view summarized
• Computer Simulation was always accompanied by
narratives that helped to
– Allow scientists to embed their work into a larger context
– Allow the general public to put scientific work into their
non-scientific context
• Narratives shape the way we think about computers
and simulation
• Classical narratives are shaken by the break down of
extremely fast technological progress.

Summary
• HPC an Society are driven by different issues
– HPC is driven by technology
– Society is driven by basic questions of the future
• HPC and Society are linked
– Society has a narrative of HPC closely related to a general
IT view
– HPC can contribute to solutions of questions of the
future but needs to be aware of its limitations
• HPC and Society need an open dialogue for a mutual
understanding of simulation
