Block Jacobi with ILU as the solver on each block. Each block corresponds
to an MPI process by default. So it is completely parallel it is just not a
true ILU. I the limit of one equation per processor it is just
"Local" as in serial?

I think SuperLU has a parallel
Hi Mark,
Yes it doesn't seem to be usable. Unfortunately we're aiming to do 3D so
direct solvers are not a viable solution and PETSc' ILU is not parallel
and we can't use HYPRE (complex arithmetic)

Fixed in the branch barry/fix-fortran-petscfileviewersetname soon to be
fixed in maint and then the next patch release of PETSc.
Thanks for the report

OK, DMComposite might be your best
Thank you very much for your reply.
My equation is a neutron diffusion equation with eigenvalues, which is why
I use DMConposite because there is a single non-physical field variable,
eigenvalue. I am not very familiar with FieldSplit. I can understand it
first.
It seems not the problem of
DMComposite is not very mature, the last time I checked and I don't of
anyone having worked on it recently, and it is probably not what you want
anyway. FieldSplit is most likely what you want.
What are your equations and discretization? eg, Stokes with cell centered
pressure? There are probably
12 matches
