SUMMARY:Can a HPC Center Ever Be Sustainable?
DESCRIPTION:Nico Formánek and Norbert Conrad (High-Performance Computing C
 enter Stuttgart)\n\nIn recent years the hpc community has increased its ef
 forts in sustainability. But cutting edge performance requires ever increa
 sing resources, above all electrical power, but also semiconductors, raw m
 aterials, cooling fluids, land and obviously money to buy all of these. In
 creases in the supply do of compute do not seem to affect demand much. For
  all sustainability efforts this means that whatever relative efficiency g
 ains can be implemented, they do not translate to an absolute reduction in
  ecological footprint. The largest target of sustainability efforts cannot
  be attacked directly, lest at the cost of performance. The demand for per
 formance is an externality which is partially imposed by society, by scien
 ce and by politics. But it also partially reflects the narratives of the h
 pc world. The aim of our talk is two fold. Firstly we will show how relati
 ve and absolute sustainability efforts of HLRS have developed historically
 . Secondly we will discuss how we, as a hpc center, have positioned us wit
 h respect to the dilemma of ever increasing absolute resource consumption.
  We close by asking if there is any prospect for changing the current hpc 
 narrative so that absolute resource reductions can become part of it.\n\nD
