Ah, so this is why threadbench has the option of skipping thread value 1024.

I don't think mine has any anomalies, but I'm not sure if I'm reading the threads benchmarking correctly

Those files look ok to me. Try some assigned DC and see if you get matching final residues. And maybe first some shorter runs on known primes with tabulated interim residues.

Laurv you're at least a dozen posts late. What's wrong with a Fermat number of pages?

Nope, not late, there's no page zero, so pages 1 to 256 can be stored in one byte
Nothing wrong with a Fermat prime number of pages, it just didn't cross my mind... I am thinking in binary, more than I am a number theorist.

If you meant pagecount-1, why isn't it there?

There's no known lossless data compression capable of even storing your comment from which that quote comes, in one byte, much less a page or multiple pages of this thread. (I get you meant page numbering, but that's not what you wrote there. And the page numbering is not zero-based.)

But to store the number you can start at 0 if a thread exists only if there is a post.)

Could. But that's not what the forum DOES. And the code to offset count would occupy space.

While examining the CudaLucas source, I noticed that it has the ability to display the relative amount of time spent in the 4 main routines while running a benckmark. Can someone enlighten me how to do thi?. It doesn't seem to be in any documentation.
TIA
