That was my thought at first, too, especially since IIRC he's 19. It's actually clear that he means primes, on a second reading of his post.

So the size of a "testable" candidate has increased roughly 500-fold in 25 years. It only needs to increase 60-fold from here in order to feasibly run billion-digit tests. Even with Moore's Law slowing down (and is it really?), 60-fold over another 25 years doesn't seem like too farfetched a goal.

One slight oversight there:
Computing clout required goes as exponent³

yeah if I beat the current record for age I might be able to get to 10 if I'm lucky.

I just finished my Prime95 AVX double check and it also reports PRIME! Hopefully one of the non-Prime95 runs will finish soon for extra-extra confirmation.

Hip! Hip!

Nice and speedy, and I assume it is a new record.

It's more than mere 'extra' - it's zeroth-order independent-software confirmation.

And independent hardware, in the case of CuLu

Anyone want to run Glucas on a PowerPC? Or even an ARM?

Batalov · 2013-01-30, 18:46

Glucas will take weeks.
Jeff was (and maybe still is) tempted to run it off-line. Pending availability of an appropriate server... for a month!

Jerry's CUDALucas run should have finished by now.
