Title: Re: endlos Post by: lycium on December 19, 2006, 11:46:57 PM 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 ;D Title: Re: endlos Post by: matera on December 20, 2006, 03:36:57 AM Nice :D
eek - I haven't made a fractal outside of Windwoes yet, shame on me! (I plead busy-ness plus laziness) Title: Re: endlos Post by: dentaku on December 20, 2006, 10:34:14 PM 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 ;D Yup, I already had a alpha version with a thread pool. 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. ;) Title: Re: endlos Post by: Nahee_Enterprises on December 22, 2006, 09:24:03 AM Greetings M. Hilpert (dentaku), and Welcome to this Forum. :)
An interesting application you have made available. Will be following its progress as you develop it. Title: Re: endlos Post by: dentaku2 on January 15, 2007, 01:20:56 AM (http://sourceforge.net/dbimage.php?id=106636)
