[petsc-users] Motivation for default KSP solver and PC

[Luciano Siqueira]

Hi *,

I'm experimenting with different combinations of KSP solvers and PCs and 
I don't know why GMRES/bjacobi are the default choices for CPU and 
GMRES/icc are the default choices for GPU. Does anyone know the reason 
for that?

Thanks,
Luciano.
