VALТребование файлов было не в логах, а в окне консоли, где море текста, там даже не сам yafu требовал, а винда ругнулась на отсутствие файла ("..." не является выполнимой командой или как-то так). В логах yafu при этом и было пусто.
Удобнее разбираться на том числе
n+8, там за час-полтора yafu нагеренит задание для gnfs и потом уже можно просто его снова запускать и смотреть что будет, времени ведь уже не тратится. Во всяком случае у меня кроме распаковки двух файлов ничего более не потребовалось и запускал просто сам yafu повтором той же команды.
HuzGiven that the gnfs-win64-ivybridge-asm64.zip file is dated 2013, it is obvious that somewhere there is a repository with the ability to select this particular build option, it is unlikely that in 2016 these options were suddenly removed from the sources ( and even if they were removed, they would remain in history).
Perhaps these options are worked out only under windows, but I can’t help here.
Of the available options, I would suggest trying AMD Opteron / Athlon64 (k8) - this is at least x64, and Opteron did not seem to support anything that is not in the i9-9900 (well, except for a few of its specific AMD64 commands,), but here I'm not sure by 100%. If it doesn’t work out (it won’t start or crashes by errors), then a good option is Intel 64-bit-capable Xeon / Pentium - again because of x64, I don’t remember Intel architectures with x64 support and without support for at least SSE3 (in Opteron it has end of 2004). The Intel Pentium M version is worse, it does not support either x64 or SSE3, probably Intel Pentium 4 with SSE3 will be better. I see no other way out than to take and try, digging into the sources is most likely more difficult and longer.
Я, например, уже экспериментировал: брал только паттерны, где квадрат простого выбрасывался только с первого или с последнего места. Это 1/6 всех паттернов. И все 8 находок в таблице именно из таких паттернов. Обратите внимание на то, что каждое из плохих чисел — степень двойки.

Т.е. отсутствие квадрата скорее характерно для поиска по строкам, видимо для этого диапазона чисел (1e34-1e38) заметно более вероятны много простых в первой степени чем хотя бы одно простое в квадрате. Но низкая вероятность не отменяет факта наличия. Если Вам неважно пропустить подходящую 14-ку, то да, можно и потребовать отсутствия квадрата, особенно если это ускорит счёт (1/6 паттернов это прекрасно).
