[petsc-users] ILU MPI

[Oliver Browne]

Hi,

Could someone explain if there is any difference in these two approaches 
when it comes to MPI. When using ILU and running with;

-sub_pc_type ilu -sub_pc_factor_levels 1 -sub_ksp_type preonly

or using the external package hypre;

-pc_type hypre -pc_hypre_type euclid -pc_hypre_euclid_levels k

Thanks

Ollie
