[petsc-dev] PetscSF vs VecScatter

[Blaise A Bourdin]

Hi,

What is PETSc’s vision for VecScatter and PetscSF?

It seems that the only thing that prevents PetscSF from completely replacing VecScatter right now is that it does not support operations (ADD_VALUES, INSERT_VALUES). Is this an inherent restriction to SF that will force it to coexists with VecScatter, or is there a plan to add support for operations and gradually replace VecScatter with PetscSF?

Regards,
Blaise
