- The Support Operator Methodology has been extended to 3-D Unstructured
- For standard preconditioners, solution times for SO are slightly
better than MH.
- For the specialized low-order preconditioners, solution times for SO
are slightly worse than MH.
- Vanilla AMG works much better on MH than SO.
- Both methods provide second-order accurate solutions.
Parallel versions of Augustus and Spartan (a multi-group SPN
are being developed.
