10:Computational Infrastructure
Requirements:
- 2 Black Holes, orbiting each other at first, and then coalescing.
- Require the outer boundary of the cauchy code to be at least 8M away from the inner boundary.
- Require the inner boundaries have sufficient resolution.
Need: A parallel code which uses Adaptive Mesh Refinement.
- At the time of the onset of the BBH grand challenge there was no infrastructure to help us.
- Browne, Parashar developed DAGH (Distributed Adaptive Grid Hierarchies).
