Hi Johannes,
So I finally got oprofile to work (FYI its what the AMD Codeanalyst thing is based one, actually links to) with:
opcontrol --i pd -p library
with the non-striped pd binary.
So here is the results:
CPU: AMD64 processors, speed 2003.16 MHz (estimated) Counted CPU_CLK_UNHALTED events (Cycles outside of halt state) with a unit mask of 0x00 (No unit mask) count 100000 CPU_CLK_UNHALT...| samples| %| ------------------ 4693599 100.000 pd CPU_CLK_UNHALT...| samples| %| ------------------ 2671578 56.9196 libGLcore.so.1.0.7664 1129198 24.0583 Gem.pd_linux 256682 5.4688 libc-2.3.6.so 247330 5.2695 libfreetype.so.6.3.5 212402 4.5254 pd 127621 2.7190 libGL.so.1.0.7664 38593 0.8222 libX11.so.6.2 5956 0.1269 zero 2353 0.0501 libpthread-2.3.6.so 1093 0.0233 libGLU.so.1.3 793 0.0169 comport.pd_linux
So clearly its the nvidia driver sucking up all the CPU.
So I downloaded 8756 and I'm going to try that, though I have to recompile my kernel since I've gone up to gcc 4 since compiling the driver and kernel, and they both have to match...
So onto kernel compilation...
Johannes, what kernel/nvidia driver/gcc are you using?
I'll be at 2.6.16,gcc4,nvidia 8756 if I get this line of thought to work.

Hi Chris,
I'm downloading "codeanalyst" TMTMTMTM now.
also googling on why oprofile may not be seeing my gem symbols.. (oprofile is also mentioned on the AMD site)
blechmann, help!

Hey all,
we'll I've narrowed down the issue to lots of pix_buffer writing, but I can't be sure without getting the profiling to work. No matter what I do oprofile just shows me pd symbols, not the gem ones.
Did you try the AMD profiler? It is pretty easy to use and profiles all running processes on the machine. It will even read the source code and point out which lines of code took time in the sample. The GUI isn't Apple level of slick but it will show useful info. _______________________________________________ GEM-dev mailing list GEM-dev@iem.at http://lists.puredata.info/listinfo/gem-dev
