OK, page updated.
Many thanks to all for your help ! Note : I don't specify merges for sequences that end on a prime number, like 29^50. Because anyway, all the sequences that end merge with another one towards the end, as Happy5214 says in post #613 !

In actual progress news, I'm finished with 21^82 and 21^84, and those are released. Last fiddled with by Happy5214 on 20201009 at 11:11

Using the tune function of yafu on my i3 results in a siqs/gnfs crossover at C104 for that laptop. On my i7, the yafu crossover is C106.

The table elements for base 72 through exponent 88 are complete (although the table is not shown due to corrupted sequences within the db).
For all of the corrupted sequences, index 1 and beyond has been entered into the db, so when the initial terms are fixed all will be available as normal. In the meantime, for anyone maintaining a local set of .elfs for their study, I have attached a correct set of the corrupted sequences.

For CADO vs siqs, my cutoff is 93 digits. CADO is over twice as fast as yafu by 99 digits. Doesn't help windows users, alas.

Yafu siqs is very fast / fine tuned. Except for very old versions and CPU, the cutoffs were always around 100 digits, a bit over. I also get 103..106 depending on what else the computer does.

Similar work can be done for factmsieve/GGNFS, particularly on the relationswanted values that trigger the first filtering run. I haven't run factmsieve in quite a while, but I think the stock settings filter a whole bunch of times, stalling sieving quite a bit. Edit I've never run GGNFS controlled by Yafu, so I can't comment on its efficiency. My best CADO C100 timing is a tick under 6 minutes wallclock time, on a singlesocket Xeon 12x2.5Ghz. On an haswelli7 (6x3.3ghz), I have 9.5 minutes for C101 on CADO. On C93, I have 226 sec on CADO, 229 sec on siqs (both 12threaded on 12 cores). EDIT: As noted in the abovereferenced thread, Skylakeyafu using AVX512 is much faster, with a crossover to CADO around 9798 digits. Last fiddled with by VBCurtis on 20201009 at 18:34

Yafu siqs on 93 digit semiprime (p47*p47) on 10 cores, 10 threads, ~84k relations needed, 166 seconds.
NFS on the same number is about Last fiddled with by LaurV on 20201009 at 18:50
