This is not hijacking, as this is discussing the LL-DC assignment policy (proposed by George) impacted by the new PRP-VDF work.

The main point is even users have no response after a resonable time frame, that doesn't mean they want to contribute their machines for pure DC work either. They may prefer their mprime to be...

That's just a meaning of important update, not means we should call it security update.

It's indeed that there shouldn't be automatically update for this kind of software. But this is an important update that can be seen as necessary security update. Sure, old machines that do other...

No, silence usually means to accept the default option. If the user doesn't response for quite a while(for example, 1 year), that usually means it's Okay for their machine to update to a newer...

I agree with that. And some measures need to be considered to deal with LL first test, like the idea I mentioned.

I agree with that. Most likely MM127 is not prime, thus primes in Catalan-Mersenne sequence end at M127. :smile:

Yes, it's found by trial division. I modified the original mmff (with minor change) to factor this kind of "Mersenne plus two"("Wagstaff Mersenne") number. (WM31, WM61, WM89, WM107, WM127)

MM127+2 has a non-trivial factor

MM127+2 (aka 2^(2^127-1)+1) has a non-trivial factor: 886407410000361345663448535540258622490179142922169401.
It seems either New Mersenne (Wagstaff) conjecture will be false(if MM127 is prime) or...

In my view, the default power should be 10 or even bigger. 10(or dozens of) GB free space is not too much for current PCs or most servers. But for most PCs/servers, it would cost a lot on hardware to...

Tesla T4 is mainly used for trial factorting(really fast). It's a little bit waste to use it for LL/PRP -- it's not very faster than K80/P4. The fastest GPU for LL/PRP is P100, thus mainly used for...

Try the previous version I provided last year. Maybe optimizations in newer gpuowl caused unstable run, or the compiled new binary isn't well itself.
