That is actually better than expected, you found 29 factors in about 2100 candidates, which is 1 in 72.4, while from the P-1 done, you would expect 1 in about 85 (the chance is about 1 in 71 for 70 to 71 bits, but that if no P-1 done).

That 29 is from 69 to 71, actually.

oh, then it is a bit disappointing, you come about, say, 10-15 factors short

On the other front, as Dylan came with the second factor, I decided to change my priorities and put all GPUs on 11.1M, redid the range he did (it took me about 2-3 hours) and came out with the third factor which he missed, and in this very right moment I am overtaking him. I have the feeling we will get complaints soon... (when he will try to report next work and see that it was not needed, unless he is using the script he posted here around somewhere, and it is unattended, in which case it will take a while till he will realize). We have a proverb in our country, "better than my mom crying, is your mom crying". Let him to be the one wasting resources, and not me

I've started 12.3. Hopefully I get a few more factors in this batch.

I made all candidates not currently being processed available to TF to 70 in the 10M to 20M range. Reb immediately brought all these in "to work" for his swarm. Sweet!!! As I said in my PMs... Let's get this party started! Last fiddled with by chalsall on 2021-08-03 at 21:27 Reason: s/I make/I made/; # This was a manual proccess. Not an automated system. Perhaps I talk too much...
 2021-08-04, 08:16 #636 LaurV Romulan Interpreter     "name field" Jun 2011 Thailand 2·3·5·7·47 Posts I just notified Dylan on PM that he is wasting resources. Hopefully he will read it. It seems he is busy with RL and doesn't read the forum recently, and the incriminated machine continues to report P-1 work behind of me, to lower limits than I used (ex: see here, and here), and it is a pity for those wasted resources and time: he can't find ANY factor using lower bounds, unless my GPU produced crap (which is not excluded, but it is very low probably, as those colab toys all have ECC). Hopefully he will read it and move to some range suggested by Wayne above. In case he wanna stay in the low expo range, there is still a lot of P-1 to be done around (end of 10M, or beginning of 12M). Last fiddled with by LaurV on 2021-08-04 at 08:17
