Cc: petsc-dev@mcs.anl.gov Subject: Re: [petsc-dev] Nested event logging and human friendly output Hi Chris, Indeed, this is exactly the issue. When we investigated this it seemed to work on Barry's system, but it has never worked on mine either. The browsers do not allow hard paths to be used for the xml style sheet. For Chrome there is an extra thing. If you launch Chrome with the flag '--allow-file-access-from-files' it should give the desired result (see here<https://stackoverflow.com/questions/39174013/why-isnt-my-xml-and-xslt-stylesheet-not-loading-in-chrome>). A note in the manual would surely be a good thing.

The xml log has this header in my case: <?xml-stylesheet type="text/xsl" href="/home/cklaij/ReFRESCO/Dev/trunk/Libs/build/petsc-3.8.3-dbg/share/petsc/xml/performance_xml2html.xsl"?> Even though the path is correct, both Firefox and Chrome on linux do not load the stylesheet. I have to 1) copy "performance_xml2html.xsl" to the directory which contains the xml log (a symlink won't do), 2) then edit the header to href="performance_xml2html.xsl". These steps work for Firefox, but not for Chrome (it just shows a blank page). If I remember correctly (Koos?) then this problem was due to some browser safety stuff which can't be avoided. If this is still true and not fixable, we should probably add a note in the manual explaining both steps? Chris dr. ir.

The missing MatAssemblyBegin could be because its time falls under the threshold of 0.01% of the total runtime, in which case it is left out of the tree. I ran the same case, and I got both Begin/End operations, but both at 0% (so probably both dwindling around the 0.01% threshold). The MatAssemblyBegin/MatAssemblyEnd pair are part of the SNESSolve routine, but they are not located within the SNES_Solve log event. This event only registers the time spent in the solve routine in snes->ops->solve. If I set an event around the call to SNESSolve in ex19.c, they do appear within that event. Maybe something to do with MatInterpolate or DMInterpolate? Since the log events have never been used in a nested logging before, it could be that this type of misunderstanding will occur more often whenever a log event is not one-to-one coupled to its routine but to a section within that routine.

The attached patch file should work on commit c03b0cd 2016-07-07 | Merge branch 'stefano_zampini/hypre-ams-zerointerior-feature' What I have found is the following: - There were some issues with the merging of the code into the Petsc code base. I have reviewed the merge and fixed this (mainly the section around depth/maxdepth determination). - There was indeed a fundamental issue, concerning a wrong assumption that the PetscLogEvent id =0 was reserved for the overall 'awake' root event. As it was also used for a normal event, this normal event was mistakenly considered as the root event which caused some trouble. I fixed the code. The issue of the single-event example giving a crash is now resolved as well. - When running snes/examples/tutorial/ex56, I found that a timer in DMPlexDistribute was not properly ended. If fixed this. With regard to the latter I wonder why the 'standard' timer events did not notice the fact that the DMPLEX_Distribute was not closed and that it should count as the event with the longest evaluation time. Could it be that the logging disregards any timers that are still open? I was thinking of including a warning message in the nested timers for any open timers at the time of the log generation, but I haven't done that for now. One thing that is still open is the fact that the nested timers are only considering the timings of the events as far as they are logged in the Main Stage. Timings in other stages are simply ignored. For instance, with the example snes/examples/tutorial/ex56.c, we will only get meaningful nested timing information from the ascii_xml viewer if we set log_stages = PETSC_FALSE on line 13. For now, I see three possible approaches to resolve this: - Tell the users that they should turn off stages in their code if they would like to use the nested timers. Given the fact that the nested timer functionality basically makes the stages obsolete, this could be a future option. - After the Main Stage is pushed in PetscLogInitialize, disable the PetscLogStagePush() and PetscLogStagePop() functionality if the ascii_xml viewer is selected for output. - Adjust the xmllogevent functions to consider the eventPerfInfo array of all stages that are in use. This is however a complex code adjustment which I would not prefer to do, also given the fact that the staging functionality is not relevant for the nested timers. Please let me know what you think of the above. Could you please include the patch in the Petsc code?

So if some function is called from multiple locations in the code, these instances are distinguished. This in contrast with the standard event logger, which only logs the amount of total call time. - It allows the output report to be formatted in XML format. This output can then be viewed in a human-friendly form in a web browser with the use of the XSL Transformation script performance_xml2html.xsl. The html features an nested timings tree that can be expanded and collapsed as desired. This tool has been very useful for us to analyze the code and pinpoint performance bottle necks. We think that it can be useful for others as well, and therefore we are providing the code here for integration in the open source distribution of PETSc. For more information I refer to the included manual. We have also provided a test program and a makefile for convenience. The test program can be run using MPI with for instance 3-6 processes. I apologize for not using the git repo to submit the developed code. I also apologize for not adhering to the PETSc coding standards (or at least not as far as I know), but I hope that it is not too far off.. Apart from the whole capital/underscore standardization stuff one issue may require special attention, namely the (ab)use of the format PETSc_VIEWER_ASCII_IMPL for signaling the XML format in XMLViewer.c. I couldn't find an already existing and better fitting format, but it could be necessary to add a new format here for this purpose. Can you take it up from here and realize the integration of the code in the PETSc distribution?
