The best profiler for linux is oprofile, but it is a pain to figure out. I've forgotten how to use it by now, though I left a bit of a bread crumb trail (~bigler/manta/trunk/arachne-opt/opstuff.history). I've been meaning to try and get a tutorial up.

As far as benchmarking goes, see BenchHelper in trunk/StandAlone/manta.cc. There are also other examples of how to do this.

The best thing for benchmarking is this:

bin/manta -nodisplaybench ...

It will run manta with no display and do a benchmark of 100 frames after a 10 frame warmup (see manta.cc).

Hello peoples,
anyone know how to get the displayed frame rate to be an average over some set time in make_scene? Or perhaps a function I can make that is called every frame so I can do it myself? As the framerate gets higher it gets more spastic. I also need a decent profiler if anyone can recommend one for linux. I don't have an intel mac so shark is out of the question. I've heard vtune (sounds like a music player to me) is good but have been unable to get a license for it. Support for parallelism is a plus.
thanks for any help,
Carson
