SUMMARY:P25 - Utopia: a Hardware Portable Library for Large Scale Simulati
 ons in Computational Geophysics
DESCRIPTION:Poster\n\nP25 - Utopia: a Hardware Portable Library for Large 
 Scale Simulations in Computational Geophysics\n\nZulian, Kopanicakova, Nes
 tola, Ganellari, Fadel...\n\nWe present Utopia, an open-source C++ library
  for parallel non-linear multilevel solution strategies. Utopia provides t
 he advantages of high-level programming interfaces while at the same time 
 a framework to access low-level data structures without breaking code enca
 psulation. Complex numerical procedures can be expressed with few lines of
  code, and evaluated by different implementations, libraries, or computing
  hardware. In this poster, first, we illustrate a globally convergent solu
 tion strategy designed to solve non-convex constrained minimization proble
 ms. Second, we provide an overview of its implementation and provide an ov
 erview of its parallel performance. Third, we provide simulation. examples
  of pressure-induced phase-field fracture propagation in large and complex
  fracture networks. Solving such problems is deemed challenging even for a
  few fractures, however, here we are considering networks of realistic siz
 e with up to 1000 fractures.
