looks like a nice system, in particular the windowing  from a quick look at the code, it seems you're doing a uniform split of the image for each thread; for better load balancing you could (statically) interleave the segments or implement a thread pool - this could matter a lot with highly inhomogeneous workloads and/or many cores (in my apps that's always made a pretty big difference, like 15%). btw, 55 degrees, isn't that getting a little hot?! btwbtw, cool name  |

Nice  eek - I haven't made a fractal outside of Windwoes yet, shame on me! (I plead busy-ness plus laziness) |

But it didn't help on performance on my machine. I also get a faster visual feedback if I use more threads than cores are available. I run a 64 Bit Ubuntu Linux on an AMD X2 3800+ EE. 55 Degrees is the absolut maximum I ever had - just to mention: I always have BOINC running in the background. And during my search for a good screenshot pic, I disabled cool&quiet and it bumped up from 42 degrees.  |

I got this one by playing with a Julia fractal (demo "Julia Island" of endlos) but with a negative exponent and a basic color function:  |
