[petsc-users] Weighted Jacobi

[Timothée Nicolas]

Hi all,

Is weighted Jacobi available as a preconditioner ? I can't find it in the
list of preconditioners. If not, what is the rationale between this choice
? It is pretty straightforward to code, so if it is not available I can do
it without problem I guess, but I am just wondering. In the matrix-free
case where SOR is not available by default, it may be better than pure
Jacobi, and much easier to parallelize than SOR.

Best

Timothee
