[petsc-users] no profile printed by "PetscLogPrintSummary"

Thanks Barry for the suggestion.
I reviewed code before, which show "-log_summary" option will trigger
1, "PetscLogBegin" in "PetscSetHelpVersionFunctions";
2, "PetscLogPrintSummary(PETSC_COMM_WORLD,0)" in "PetscFinalize".
So, I tried the following code:
PetscInitialize(0, 0, 0, 0);
PetscLogBegin();
...
PetscLogPrintSummary(PETSC_COMM_WORLD, 0);
PetscFinalize();
But, don't get the log summary, then I asked the question to see if I missed something.
Thanks,
Debao

1) switch to petsc 3.2
2) be proactive. It may seem easier to send email with a question but in fact that takes time for people to respond and figure out what you are asking. Looking at the code will be faster. See the instructions for searching through source code in
the users manual http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/docs/manual.pdf page 174 Then you can search the PETSc source for -log_summary and track what function it actually calls to print the summary information. The answer of "how" is always in the PETSc source code. (Sometimes "why" we did something a particular way cannot be found in the source).

These don't print the summary, they tell PETSc to start logging it.
