1 | Fortran90 (array syntax) very attractive to handle equations which are naturally written in Tensor (multi-dimensional) form |
2 | 12 independent field values defined on a mesh with black holes excised -- non trivial dynamic irregularity as holes rotate and spiral into each other in interesting domain |
3 | Irregular dynamic mesh is not so natural in (parallel) Fortran 90 and one needs technology (including distributed data structures like DAGH) to support adaptive finite difference codes. |
4 | Separate Holes are simulated till Merger |
5 | 0.7 |
6 | 6.9 |
7 | 13.2 |
