1) Message boards : General discussion : an idea for speeding up LLR testing (Message 150965)
Posted 83 days ago by Pavel Atnashev
Not to mention twofold increase in cache and memory bandwidth requirements.

The first rule: one should keep FFT size as small as possible.

SoB challenge! ♥️

Also, DC task is protected by Gerbicz check too.
4) Message boards : Number crunching : Effect of single vs dual rank on task duration (Message 145717)
Posted 324 days ago by Pavel Atnashev
Some of my setups are quad channel dual rank. That's the best for things like P-1 sieving.

I have tested a lot of different configurations, and double rank is definitely better than single rank when a task requires main memory access. Of course, fitting everything in L3 cache is the best, but when you need memory, go for double rank.

Done.

It was very much due, a fun thing, though - primes tend to come in pairs or in close alinesness - so if those that crunched at the time prior to this prime, continue their effort, we might in fact see 2 conjecture primes for a base 2 conjecture in 2020 :)

Yeah, I thought about prime pairs too. It's kind of a superstition, but if someone feels lucky, now is the time to try find another one. I've moved to ESP.

Thanks!
10) Message boards : Number crunching : Which conjecture most likely to find a prime? (Message 144262)

Yes, but with a linear coefficient.
