SUMMARY:High Performance Computing for Different First Order Formulations 
 of the Einstein Equations
DESCRIPTION:Minisymposium\n\nOlindo Zanotti (University of Trento)\n\nThe 
 solution of the Einstein--Euler equations by the vast majority of numerica
 l codes is still based on traditional finite difference schemes\nfor the E
 instein sector, while it relies on conservative schemes for the matter par
 t. Discontinuous Galerkin  (DG) schemes, in spite of many potential\nadvan
 tages, have not reached a mature stage yet. I will compare performances of
  a new class of finite difference schemes for the full Einstein--Euler\neq
 uations with DG schemes, showing possible future directions of research th
 at may promote DG schemes to be the dominant ones in a future with exascal
 e hardware. In the last part of the talk I will discuss the impact of  mac
 hine learning on the data analysis of gravitational waves observations.\n\
 nDomain: Climate, Weather, and Earth Sciences, Engineering, Physics, Compu
 tational Methods and Applied Mathematics\n\nSession Chairs: Eike Mueller (
 University of Bath) and Tobias Weinzierl (Durham University)
