We describe basic physics and computational features of Binary Black Collision Grand Challenge
We show a simple finite difference is complicated by
  • Adaptive Mesh refinement
  • Complex inner and outer boundary conditions
  • Need for several algorithms for hyberbolic and elliptic parts of problem
MPI or more generally message passing is not obsolete but rather the only complete solution!
Higher level systems DAGH and especially HPF cannot express full complexity of problem and MPI must fill in the missing parts
HPF2 might be able to express full problem but HPF1 misses many key capabilities
DAGH is more succesful than HPF1 but needs MPI for parts of problem
