I found that the range 15.20M to 15.22M has no P-1 done. If you want, I can run P-1 in that range.

Mike and I are working through the entire 15.2M range.
We've so far completed about 25-40% of the ranges you mentioned.
We expect to finish in about 3 or 4 days.

Chris put his entire GPU72 team to help 15.5M.
They are also only a few days from finishing.

The ranges that actually seem to need help are 8.1, 8.7 and 15.6.
They have the least remaining but they are working solo.
I was going to help there if required after 15.2M .... or you could offer.
If I/we can arrange to do so without getting in each others way.

Regardless, it appears the last factor should be found within less than a week.

Thanks

5 ranges, less than 50 factors to go, from which 23 in 15M2.

As it seems, all will be finished tonight except for the 15.2, so my suggestion is to let Wayne work the 15.2 alone, so he will be busy for a month or two and won't bother us with other projects... :razz:

Joking apart, congrats guys, you all did a wonderful job!

According to [url]https://mersenne.ca[/url], there is a new factor for 8.1 and 8.7 per day and a new factor for 15.6 in 2 days. This means that these ranges should be finished in about one week. So no help appears to be needed there.

[QUOTE=linament;598047]I'd like to join the game. Could I reserve 8.7 for P-1? I may do some TF, but not sure my GPU will keep up. So, if anyone else feels the urge, TF is welcome.[/QUOTE]

If I am reading it right you are focusing on certain sub-sub ranges that are still over 200 Factors.
So do you mind if I P-1 in ranges already below 200...i.e. say 8.73M?

Thanks

 linament 2022-04-12 04:44

Sure, 8.73M. 8.77M or 8.79M are ones I wasn't planning on working. I don't know what it is going to take to get 8.78M under 200 since I have done P-1 on all of them to at least 8000000 for B1.

One option is another TF level.
Statistically even with all the P-1 there's a decent chance it would find the last 7 factors.

No no that is not right...sorry.
At least 7 factors in all of 8.7M. Might be only 1 or 2 in 8.78M.

So the best choices are even deeper P1 or ECM. If you kept the P1 save files you don't have to start from zero.

This should be the last week.

All 1M ranges are now under 20,000 Factors; the last to fall was 15M today.
The 5 remaining ranges of interest are all under 20 factors to go.

29 total factors remaining 15, 6, 3, 3, 2 to be exact.

 petrw1 2022-04-14 05:19

@firejuggler: do have any issue if I grab some 15.6M assignments to help finish it?

24 hours later and we are down to 19 factors remaining in 5 ranges; all needing less than 10 more factors:9,4,3,2,1

All times are UTC. The time now is 07:16.
