[petsc-users] Enquiry regarding log summary results

Hi,

I'm doing a log summary for my 3d cfd code. I have some questions:

1. if I'm solving 3 linear equations using ksp, is the result given in 
the log summary the total of the 3 linear eqns' performance? How can I 
get the performance for each individual eqn?

2. If I run my code for 10 time steps, does the log summary gives the 
total or avg performance/ratio?

3. Besides PETSc, I'm also using HYPRE's native geometric MG (Struct) to 
solve my Cartesian's grid CFD poisson eqn. Is there any way I can use 
PETSc's log summary to get HYPRE's performance? If I use boomerAMG thru 
PETSc, can I get its performance?

Yours sincerely,
