Making a 4K Fractal Movie with Fractal eXtreme
Four years ago I created a HD fractal movie because I wanted to see how quickly Fractal eXtreme could calculate the same movie that Orson Wang had posted to youtube. My version of his movie was antialiased and 720p and … Continue reading
Out of Order Benefits
A few months ago I wrote about some experiments to see how fast modern CPUs are at doing highprecision math such as is used in cryptography and highprecision fractal calculations. I recently read an article that claimed that outoforder processors … Continue reading

Fractal eXtreme, now cheaper
As an experiment Fractal eXtreme is now just $9.95. The latest version has a few bug fixes and performance improvements, is a free update to all existing users, and is cheap like borscht.
Fractal and Crypto Performance
There was some recent interest in what type of computer would run Fractal eXtreme’s deep zoom calculations fastest (and cheapest) so I wrote a benchmarking tool that isolates the inner calculations for more accurate measurements and arranged to have it … Continue reading

Fractal eXtreme New Version–Better Zoom Movies
While working on the Really Deep Fractal Zoom Movie – Much Faster project (240 times faster!) several updates were made to Fractal eXtreme in order to improve the creating of zoom movies. These improvements are now available as part of … Continue reading

Really Deep Fractal Zoom Movie – Much Faster
A few weeks ago while browsing YouTube for Fractal movies I came across a video that claimed to be (as of its post date of January 26, 2010) the deepest zoom movie on YouTube. The video was of an interesting … Continue reading

Faster Fractals Again
I was calculating a long fractal zoom movie with Fractal eXtreme when I noticed that one of the phases seemed to be taking too long on my fourcore eightthread processor. A bit of investigation showed that this phase was effectively … Continue reading

Then and Now–Performance Improvements
In a recent post I made an offhand comment that in one fractal calculation scenario my new laptop is about 37,500 times faster than my old Amiga 1000. I suspected that in other fractal calculation scenarios the improvement is much … Continue reading

Faster Fractals Through Better Scheduling
Performance improvements can come from many directions including better algorithms or microoptimized inner loops. In this case I got a worthwhile speedup by working better with the Windows thread scheduler.

Faster Fractals Through Algebra
I’ve been working on Fractal eXtreme onandoff for years, and an important (and fun) part of working on it is optimizing the calculation of the Mandelbrot set, especially the highprecision math routines that allow deepzooming. After working on this over … Continue reading
