Thanks for the update. I have "released" that range from curation.

12.1, 12.3 and 12.6 are most in need or more TF.

But up to firejuggler

A recommendation for all users. Concentrate your P-1 efforts on larger exponents. 30.8 has some exciting P-1 developments coming. The smaller the exponent, the more P-1 will benefit from the new code.

I'll rush an emergency pre-beta to this group as soon as I can.

How low is "low"?
With 1 exception we are down to 29.8M.
Most of the effort is in the 2x.xM ranges.

Not sure if you want B1/B2 as well. If not feel free to modify.

Wavefront:
Pminus1=N/A,1,2,26899799,-1,1000000,30000000
Pminus1=N/A,1,2,26899981,-1,1000000,30000000

Smaller:
Pminus1=N/A,1,2,9100033,-1,1000000,30000000
Pminus1=N/A,1,2,9100051,-1,1000000,30000000

I just achieved 1 of my long term wishes, had Team_Inspector successfully certified 1 of my PRPs -> M2271301.

I believe this will bring me some future lucks.

Ok, so I will do P-1 on the 12.0M range. It will take a couple of weeks, I guess. Could you please "release" the range for me?
As for TF, I won´t be doing any in the twok ranges. My GPU is simply too slow. I´ve run several TF tests to 73 bits in the 12.9 M range, supposing no one was working there. Not a lot, and no factor found, but if Anon is reading this will probably wish to remove those work units from the worktodo file to avoid duplication.

Certs are something that the server randomly assigns. Except for the ones that George posts in the Strategic DC thread, you can't self-assign certs. I have done over 700 certs in the last year. So, it is no big deal that I happened to get assigned yours. I haven't touched the machine that did for about a week. It runs all by itself.

 2021-11-24, 04:31 #924 SethTro     "Seth" Apr 2019 19×23 Posts With James's help (thanks for everything). I rigged up a P-1 calculator in python and tried to optimize TF vs P-1. I use a similiar methodology to what Wayne does. If anyone is curious my code is at twok_hard.py but it needs extra data and setup. It also makes a bunch of assumptions (all exponents have the same existing B1/B2, TF success of 1/ (bits + 5), ...) that I might refine. I think it should still be a reasonable estimate of how much work is left for each range Code: [17000000,17100000] 156 needed, current TF 2155 x 72 Existing P-1 for interval greater than B1=100000, B2=2025000 => 2.0% Last P-1 2155 x 9.6% @ B1=20405627 B2=413213953 0 GPU(72) + 74390.0 CPU | GHz-Days/factor GPU: 0.0 CPU: 476.9 | 0.0x GPU/CPU Factors/Tests 0.0/0 TF + 156.0/2155 P-1 @ B1=20405627 B2=413213953 Existing P-1 for interval greater than B1=100000, B2=2025000 => 1.8% Last P-1 2155 x 8.0% @ B1=11808812 B2=239128445 60443 GPU(73) + 43049.8 CPU | GHz-Days/factor GPU: 2159.7 CPU: 336.3 | 1.4x GPU/CPU Factors/Tests 28.0/2155 TF + 128.0/2155 P-1 @ B1=11808812 B2=239128445 Existing P-1 for interval greater than B1=100000, B2=2025000 => 1.6% Last P-1 2155 x 6.3% @ B1=5694836 B2=115320430 181329 GPU(74) + 20760.9 CPU | GHz-Days/factor GPU: 3260.4 CPU: 206.8 | 8.7x GPU/CPU Factors/Tests 55.6/4310 TF + 100.4/2155 P-1 @ B1=5694836 B2=115320430 Existing P-1 for interval greater than B1=100000, B2=2025000 => 1.4% Last P-1 2155 x 5.0% @ B1=3295622 B2=66736360 423100 GPU(75) + 12014.4 CPU | GHz-Days/factor GPU: 5104.1 CPU: 164.3 | 35.2x GPU/CPU Factors/Tests 82.9/6465 TF + 73.1/2155 P-1 @ B1=3295622 B2=66736360 Existing P-1 for interval greater than B1=100000, B2=2025000 => 1.2% Last P-1 2155 x 3.5% @ B1=1324436 B2=26819846 906644 GPU(76) + 4828.3 CPU | GHz-Days/factor GPU: 8254.9 CPU: 104.6 | 187.8x GPU/CPU Factors/Tests 109.8/8620 TF + 46.2/2155 P-1 @ B1=1324436 B2=26819846 Existing P-1 for interval greater than B1=100000, B2=2025000 => 1.1% Last P-1 2155 x 2.0% @ B1=369626 B2=7484926 1873731 GPU(77) + 1347.5 CPU | GHz-Days/factor GPU: 13733.4 CPU: 68.9 | 1390.5x GPU/CPU Factors/Tests 136.4/10775 TF + 19.6/2155 P-1 @ B1=369626 B2=7484926 3314264 GPU(1605 x 78) + 0 CPU | 156/12380 TF Each block stands for completing another bitlevel of TF. Starting with no additional TF and going up to completing TF 2^77 If we do no additional TF we'll need P-1 bounds around B1=20M, B2=413M to get 156 factors from 2155 P-1 tests If we do one more bit level of TF it takes 60,400 GHz-Days (of GPU time) and we expect to find 28 factors BUT now we can do B1=12M, B2=239M with ~8% success to find the remaining 128 factors. This takes 43,000 GHz-Days (of CPU time). At the extreme we can do 3 Million GHz-Days of TF (all 2134 exponents to 2^77 + ~1605 to 2^78) It looks like the most reasonable strategy is going to be TF to 75 or 76 for this range. Depending on the actual P-1 data. I think the worst range is 29.8M Code: [29800000,29900000] 91 needed, current TF 2090 x 75 For M29,800,009 2.1% P-1: B1=208981 B2=4179626 Last P-1 2090 x 6.7% @ B1=8264681 B2=165293637 0 GPU(75) + 53097.1 CPU | GHz-Days/factor GPU: 0.0 CPU: 583.5 | 0.0x GPU/CPU Factors/Tests 0.0/0 TF + 91.0/2090 P-1 @ B1=8264681 B2=165293637 For M29,800,009 2.1% P-1: B1=268337 B2=5366746 Last P-1 2090 x 5.3% @ B1=4264749 B2=85294990 267864 GPU(76) + 27399.2 CPU | GHz-Days/factor GPU: 10253.2 CPU: 422.3 | 9.8x GPU/CPU Factors/Tests 26.1/2090 TF + 64.9/2090 P-1 @ B1=4264749 B2=85294990 For M29,800,009 2.1% P-1: B1=344552 B2=6891038 Last P-1 2090 x 4.0% @ B1=2200700 B2=44014007 803592 GPU(77) + 14138.6 CPU | GHz-Days/factor GPU: 15475.3 CPU: 361.9 | 56.8x GPU/CPU Factors/Tests 51.9/4180 TF + 39.1/2090 P-1 @ B1=2200700 B2=44014007 For M29,800,009 2.1% P-1: B1=442413 B2=8848268 1875049 GPU(78) + 5466.6 CPU | GHz-Days/factor GPU: 24220.7 CPU: 402.4 | 343.0x GPU/CPU Factors/Tests 77.4/6270 TF + 13.6/1305 P-1 @ B1=1362729.1842528547 B2=27254583.685057092 1875049 GPU(2090 x 79) + 0 CPU | 91/6270 TF
