| -pc_sor_symmetric | - Activates symmetric version | |
| -pc_sor_backward | - Activates backward version | |
| -pc_sor_forward | - Activates forward version | |
| -pc_sor_local_forward | - Activates local forward version | |
| -pc_sor_local_symmetric | - Activates local symmetric version (default version) | |
| -pc_sor_local_backward | - Activates local backward version | |
| -pc_sor_omega <omega> | - Sets omega | |
| -pc_sor_its <its> | - Sets number of iterations (default 1) | |
| -pc_sor_lits <lits> | - Sets number of local iterations (default 1) |
Notes: Only implemented for the AIJ and SeqBAIJ matrix formats. Not a true parallel SOR, in parallel this implementation corresponds to block Jacobi with SOR on each block.
For SeqBAIJ matrices this implements point-block SOR, but the omega, its, lits options are not supported.
