The list of GFN n=13 primes is now updated with the finds from August (up to b=80M).

Cheers

Heavy rain in an hour & 50mph winds overnight.

Hatton down the batches


Was it just me, or did 'Aileen' not amount to much? At least here in the NW it seemed to be not much wetter or windier than it has been for the last couple of weeks!

some humor


Are you sure, I thought everyone around here was pretty straight-laced?

I used to work with a lot of Chinese folks when I was at IBM. To make our lives easier, they would often take an English word to use in place of their first name. I don't think "Magic Wang" had any idea why we found him so amusing!

Congrats to Van on the find (and also to all the others who crunched the WUs leading up to this one)!

I was wondering only today about you. A 400 mile drive and the mind wandered even more than usual. Hope the new job is going well.


Well almost certainly better to attempt a 400 mile drive yesterday rather than on the bank holiday Monday! Things are going well so far since the move, although between the new job and renewed attack on my PhD studies I have little time and energy to spare. Am remaining (relatively) sane by racking up the miles in training for some long-ish races later in the year.

Also I saw that AVX512 should be on mainstream and server CPUs later this year. How much will that improve LLR runtime?

AVX-512 is here now in Skylake-X. It will make exactly zero difference in the short term as we need software to be updated to use it. In theory it could offer doubling of performance per clock, but apparently the few things that actually use it really heats things up, so it might not be that simple. There is also talk that ram bandwidth limiting may be more of a problem than ever.


I understand George Woltman has access to a Xeon Phi KNL which also has AVX-512, so I think gwnum support (and by extension LLR) are on the way, but no idea when it will be ready.
