GEGL Perf tools - plan

Hi,

Sorry for my silence! Normally if I don't have anything to say, I don't say it ;-)

I'm currently doing a survey of the existing tools and their capabilities. You can follow this on my site: http://sites.google.com/site/computerresearcher/profiling-tools

It's a bit patchy, but I expect to improve it as I go along.

PLAN

1. Do survey of current data collection tools (oprofile, valgrind etc etc) and select which ones to use
2. Put the data from these tools into a database 3. Creating a set of typical perf analysis scenarios (i.e. integration/regression tests)
4. Use the data to create reports and/or gui for elaborating reports. (web and/or fat-client)

I will come back to you when the survey is ready in order to get feedback on the choice of tools.

This is the moment to let me know for anyone who wants me to include a certain tool in the survey.

I'm currently at:

- gprof, sprof - valgrind (cachegrind, callgrind)
- ltrace, ptrace
- oprofile

Regards,

Henrik

GEGL itself contains built in instrumentation that allows breaking down the time spent in pixel format conversions (babl) as well as the different nodes of a composition. The small sample gallery at the website used to be part of an automatic regression testing facility operated by OSDL called crucible which did nightly builds and performance/rendering regressions. See http://www.gegl.org/gallery/clones.txt for examples of how this infrastructure breaks down processing time.

Hi,

Sysprof seems to be missing from that list

Nice to hear you are making good progress anyway!

AFAIK sysprof has a subset of the oprofile functionality, is very poorly documented and supports only x86 CPUs. This is why I don't plan on evaluating it.
