1) Message boards : Number crunching : SOB, PSP and ESP at a glance (Message 154972)
Posted 243 days ago by Pavel Atnashev
I also suggest this chart for those trying to understand SoB/PSP/ESP:

It shows current expected number of primes for each k, compared to all other k's.

Looks like I need another ESP.
3) Message boards : General discussion : an idea for speeding up LLR testing (Message 150965)

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.

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.
