Force FFTsize to be used
Hey,
I'm trying to execute nonPrimeNetwork like this (just as example): Code:
PRP=N/A,1,2,1000000,51,99,0,3,1 PRP=N/A,1,2,1000000,35181,99,0,3,1

You can enforce FFT size.
But you shouldn't  in this case. Bitsize is not the only factor for the FFT size choice. The k and/or c value will affect the FFT size too. (In this case c value is large, 35181.)

The roundoff is really small. Even then you should not decrease FFTsize?
Just out of curiosity: How do you set a specific FFT?

You should use type 5 PRP (the last 5 in the line) unless you are double checking a previous PRP result run with another type. Edit: Nevermind I missed that it was not primenet work. Last fiddled with by ATH on 20171117 at 16:32
