BarOrder
Barrier ordering algorithm
| Type: | int | |
|---|---|---|
| Default value: | -1 | |
| Minimum value: | -1 | |
| Maximum value: | 1 |
Chooses the barrier sparse matrix fill-reducing algorithm. A value of 0 chooses Approximate Minimum Degree ordering, while a value of 1 chooses Nested Dissection ordering. The default value of -1 chooses automatically. You should only modify this parameter if you notice that the barrier ordering phase is consuming a significant fraction of the overall barrier runtime.
Note: Barrier only
