Hi,
In other prime testing WUs I see an "Is prime?" row in the results table e.g. this esp test.
But genefer doesn't e.g. this WU.
Is there a reason why not?
Thanks,
Peter.

Genefer puts more information in stderr.txt than does LLR. If the same "is [not] prime" information was displayed, it would potentially allow third parties to learn about the existence of a prime before it's ready to be made public. So we don't display that line.

From a practical standpoint, GFN primes are so rare that it's also not necessary. Simply assume that there's always an "XXX is not prime" on every test. If you discover a GFN prime, or are the double checker, I guarantee you will know it. It's a big deal. You'll absolutely, positively see your name on the PrimeGrid home page, and in the notifications tab of the BOINC client. The discover also gets emailed. And there will be more than a little chatter on the forums.

Thanks Michael.
Of course, I pretty much expect every WU to be a non-prime, that's not going to stop me enjoying being a part of this great project. I was just curious.

I've been fortunate enough to find a few primes so I've had a few of those exciting emails.
Cheers,
Peter.
