Before calling this routine you must have called either PetscLogDefaultBegin() or PetscLogNestedBegin()
If PETSc is configured with --with-logging=0 then this functionality is not available
To view the nested XML format filename.xml first copy ${PETSC_DIR}/share/petsc/xml/performance_xml2html.xsl to the current directory then open filename.xml with your browser. Specific notes for certain browsers
Firefox and Internet explorer - simply open the file
Google Chrome - you must start up Chrome with the option --allow-file-access-from-files
Safari - see http://ccm.net/faq/36342-safari-how-to-enable-local-file-accessor one can use the package http://xmlsoft.org/XSLT/xsltproc2.html to translate the xml file to html and then open it with your browser.
