It takes about 8min to solve my problem using the default solver in PETSc 
and 14min using pilut from hypre. But it takes 132min to get the result if 
using the option "-pc_type hypre -pc_hypre_type boomeramg -ksp_type gmres". 
Should I change the default options for amg?
Any suggestions are welcome.
