I tried Ernst's Mlucas on the DS20, and it wanted to use 384k for M38.
I'm just trying MacLucasUNIX now, and it's done 2

I guess gcc would look "ordinary". Unfortunately linux uses the NT
We ran the DC for M38 on a DS20/500. Using Ernst's code we were getting .18
s/i, but I don't remember the FFT size. I want to say 384K? Ernst?
Cheers,

You can't test M33219281 with a 1024k FFT, you'll need a 2048k fft :(
