[petsc-users] Preconditioners memory use

[Jarunan Panyasantisuk]

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
