[petsc-dev] external preconditioner availablilty for PETSc

[Park, Heeho]

Hi PETSc developers,

I’m writing my proposal for my dissertation research at UIUC that will study on effectiveness of preconditioners for anisothermal, multiphase porous media flow calculations in parallel using PFLOTRAN. I know the link below lists preconditioners but from your experience, which preconditioning packages provide reliable and efficient PILUT, AMG, SA-AMG preconditioners for PETSc and do you have other preconditioner recommendations?
I used hypre PILUT, but the performance and the linear iteration count to solve a matrix is worse than ILU(0) which is not what I expected.
