| Most Sn transport codes are designed around one of these nestings, which is an inflexibility that leads to software engineering compromises when porting to new architectures and programming paradigms. | ||
|
|
||
| Early research has found that the problem dimensions (zones, groups, directions, scattering order) and the scaling (number of threads and MPI tasks), can make a profound difference in the performance of each of these nestings. | ||
| To our knowledge, this is a capability unique to Kripke, and should provide key insight into how data-layout affects Sn solver performance. |

@rchen20 We need details in the code modification section on what may be changed, and what should stay the same. If I am not mistaken, the data ordering (GDZ) needs to stay the same,. while the execution policy can be changed and optimizations like loop tiling are allowed.
