Power Fractal is a numerically-intensive parallel graphics application that computes a Mandelbrot-like fractal and displays processor performance statistics. This app uses the AltiVec, SSE, and multiple processors (MP) for its computations and uses UCLA AppleSeed's MacMPI library for communication between parallel processors. To run it on a Mac cluster, use Pooch. This code will also compute correctly on single processor machines and non-G4's.

What's New

Version 1.4.1: Newly reoptimized SSE code and fractal presets for the new 8-Core Mac Pro, where it can achieve over 80 GigaFlops. Thanks xlr8yourmac!

Requirements
PPC / Intel, Mac OS X 10.4 or later.

A great app to explore the beauty behind the Mandelbrot set. It really kicks on the PowerMac 2 x 2.5 GHz ... nearly 16,000 Mflops!

Feature requests:
- Zoom via rectangle selection.
- Pan the view by (say) holding down a key and dragging the mouse ala Photoshop.

My G4 shutdown when I tried to open Altivec Fractal. Guess my machine is no good.

I wanted to check whether the altivec enabler was functioning for the G4 upgrade in my Powermac.

The mac (system profile etc) doesn't give accurate information on the upgrade, so it's hard to know what's actually going on.

Your program was concise, easy to use and answered the question.

Thank you

i tested both my g4 867 powerbook and my g4 400 powerbook. results were consistent after multiple tests with and without altivec, and showed that on each computer altivec provided 4 times better performance when activated. this is good to know. good program, reliable.
