[petsc-dev] getting on with the nested timers

[Klaij, Christiaan]

Matt,

I guess you meant to send this link:

http://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/Viewer/PetscViewerPushFormat.html

If so, it doesn't say anything on XML either. But after some
trial and error I found the format to
be "PETSC_VIEWER_ASCII_XML", so problem solved.

Summarizing the problem from a user perspective:

1) The manual page of PetscLogView mentions PetscViewerASCIIOpen,
which mentions PetscViewerPushFormat, I should have figured that
out by myself, sorry.

2) The manual page of PetscLogView mentions PetscLogNestedBegin,
which doesn't have a manual entry.

3) The manual page of PetscViewerPushFormat doesn't mention the
format PETSC_VIEWER_ASCII_XML, although it is available.

Barry,

I'm still trying to use petsc's nested logging with our code. I
have it working for 3.8.3 with the command line option, for
example:

mpirun -n 3 ./refresco -log_view :performance.xml:ascii_xml

This gives the expected performance.xml file. How to get the same
without command line options? So far I have:

CALL PetscLogDefaultBegin(ierr)
...
CALL PetscViewerASCIIOpen(MPI_COMM_WORLD,'performance.xml',viewer,ierr)
CALL PetscLogView(viewer,ierr)

which gives the regular log in the performance.xml file.

I guess I should replace PetscLogDefaultBegin by
PetscLogNestedBegin as stated in the manual page of PetscLogView.

But there's no manual page for PetscLogNestedBegin and I didn't
find anything like PetscViewerASCIIOpenXML either.

http://www.mcs.anl.gov/petsc/petsc-master/docs/manualpages/Profiling/PetscLogView.html

You need to push the ASCII_XML format before viewing.

  Thanks,

     Matt
