-pc_jacobi_type <diagonal,rowmax,rowsum> | - approach for forming the preconditioner Many br | |
-pc_jacobi_abs | - use the absolute value of the diagonal entry Many br |
Many br
Notes: By using KSPSetPCSide(ksp,PC_SYMMETRIC) or -ksp_pc_side symmetric Many brcan scale each side of the matrix by the square root of the diagonal entries. Many br
Zero entries along the diagonal are replaced with the value 1.0 Many br
See PCPBJACOBI for a point-block Jacobi preconditioner Many br
