I finally have it posted!!!

Thanks to Mikkyo!


This code is working about 25% faster than the normal G5 optimized code. At top speed, this code is pushing 3500 MIPS in the average sized FFT. This puts it in line with the FFTW 3 library. Lastly, this is pushing the temperature on my CPU up near 150 degree F. Run this version at the disadvantage of a little more noise coming from your computer.

Bo-ya-ca-sha.

Any update on the G4 client?

It is probably the more in demand client as not many people have G5s.

I will post a G4 version within the next 24 hours. Probably tonight though. I'll post here.

The G4 version is seeing a 50% drop in time per work unit. The memory architecture is not as advanced at the G5.... Thus using altivec for the G4 will produce much larger advances. SWEET!
