[petsc-users] gmg vs amg

[Amneet Bhalla]

Hi All,

Is it almost always the case that for structured mesh, geometric multigrid
would be faster than algebraic multigrid solver/preconditioner?
Basically I want to know If I had a choice between pfmg , gamg and
boomeramg for structured grid what should I choose?

Thanks,
