Observations of colliding neutron stars play an + important role in nuclear astrophysics today.

SpECTRE's goal is to achieve more accurate + solutions for challenging relativistic astrophysics problems such as + core-collapse supernovae and binary neutron star mergers. The + robustness of the discontinuous Galerkin method allows for the use + of high-resolution shock capturing methods in regions where + (relativistic) shocks are found, while exploiting high-order + accuracy in smooth regions. A task-based parallelism model allows + efficient use of the largest supercomputers for problems with a + heterogeneous workload over disparate spatial and temporal scales. + We argue that the locality and algorithmic structure of + discontinuous Galerkin methods will exhibit good scalability within + a task-based parallelism framework. We demonstrate the code on a + wide variety of challenging benchmark problems in (non)-relativistic + (magneto)-hydrodynamics. We demonstrate the code's scalability + including its strong scaling on the NCSA Blue Waters supercomputer + up to the machine's full capacity of 22,380 nodes + using 671,400 threads. +---
