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

[Debao Shao]

Hi, Matt:

1, I tried both "PetscLogAllBegin()" & "PetscLogBegin()", but both of them don't print log summary.
2, I disabled MPI(--with-mpi=0), will MPI_COMM_SELF have difference to PETSC_COMM_WORLD?

Thanks,
Debao

DA,

I intend to use "PetscLogPrintSummary" to dump log summary, but don't get it.
The usage is:
    PetscInitialize(0, 0, 0, 0);
    PetscLogAllBegin();
    ...
    PetscLogPrintSummary(MPI_COMM_SELF, PETSC_NULL);
PetscFinalize();

You only need PetscLogBegin(), and you should use PETSC_COMM_WORLD.

My libpetsc.a is built by
1, ./config/configure.py --with-mpi=0 --with-debugging=1 -with-log=1 -with-info=1 --with-x=0;
2, make all

Thanks,
Debao
