Dear Petsc List, In case you have an experience about precondtiioners performance tests: Does the preconditioner Block Jacobi generally consume memory more than HYPRE/BoomerAMG? I use GMRES as a solver and -log_summary to print out the performance result. The results of my test case shows that BJACOBI uses more memory than AMG. I thought it is other way round. If you have similar results, please share your experience.
Thank you Jarunan
