My bad. 30.7 cannot read a 30.8 save file. Try your save file and "Pminus1=N/A,1,2,5903,1,200000999,200000999" with 30.8.

Oh, that did finish the P1, but it didn't report a factor. Could it be that the save file already knows the 8 factors?

I just tried the same line with the other exponents in my previous list and they all report 'complete' with no mention of any factors. Below results.txt (both B1 ending in triple zero and ending in triple 9 (with no known factors). I have kept the save files of these exponents from after the run with the 100% complete reporting bug as well as the ones after the run with no known factors.

Here are some P1 files if someone wants to take them higher B1 at some point. I was just doing random tests of v30.8:
P1files.zip I was using Pminus1BestB2=0 in prime.txt choosing my own B1/B2 limits, that is why I did not change the 66 bits factored to. Code:
1567 B1=50*10^{9} B2=10^{16} Pminus1=1,2,1567,1,50000000000,10000000000000000,"29257873823,488519841428152561,31523570928926921025805379993" 1583 B1=30*10^{9} B2=10^{16} Pminus1=1,2,1583,1,30000000000,10000000000000000,"3167,189961,8589359,43817441" 10303 B1=25*10^{9} No stage2 Pminus1=1,2,10303,1,25000000000,25000000000,66 32911 B1=5*10^{9} B2=10^{14} Pminus1=1,2,32911,1,5000000000,100000000000000,66 33091 B1=5*10^{9} B2=10^{14} Pminus1=1,2,33091,1,5000000000,100000000000000,66 33151 B1=5*10^{9} B2=10^{14} Pminus1=N/A,1,2,33151,1,5000000000,100000000000000,66 33161 B1=5*10^{9} B2=10^{14} Pminus1=N/A,1,2,33161,1,5000000000,100000000000000,66 33587 B1=5*10^{9} B2=10^{14} Pminus1=N/A,1,2,33587,1,5000000000,100000000000000,66 41927 B1=4*10^{9} B2=10^{14} Pminus1=N/A,1,2,41927,1,4000000000,100000000000000,66 44549 B1=2*10^{9} B2=10^{14} Pminus1=N/A,1,2,44549,1,2000000000,100000000000000,66 48119 B1=3*10^{9} B2=10^{14} Pminus1=N/A,1,2,48119,1,3000000000,100000000000000,66 49871 B1=10^{9} B2=10^{14} Pminus1=N/A,1,2,49871,1,1000000000,100000000000000,66 Last fiddled with by ATH on 20211216 at 23:46

One small suggestion could you make the Factor Probability column on the exponent page a link to the prob calculator with the values of that row filled in? I think it might be cleanest if you style it so the link color is black (unless hovered over)

Stage 2 needs about the same time, but you'd better decrease it to 1/6 because it can't run in parallel. so average is one exponent per week. Last fiddled with by Zhangrc on 20211217 at 00:36

Do the save files prior to the 100% reporting find known factors when the B1 bound is increased by 999?

I'm currently looking at the 40k range. I count 82 exponents from 40k41k. I'll probably attempt to take them to B1=10^9 in anticipation of better optimized multithreaded stage 2. Below an example of what probabilities I'm expecting (I'm rounding TLevel up from estimates on mersenne.ca);
No stage 2: https://www.mersenne.ca/prob.php?exp...&b1=1000000000 Stage 2 with B2=B1x800k: https://www.mersenne.ca/prob.php?exp...0&b2=8.0E%2B14 With previous posts in mind, this seems like a good range to throw my hat at! I might consider going higher than B1=10^9, but for now I'd like to start saving up lots of good B1only save files. I'm eager to hear if there are other things to consider when P1'ing in this range! From my due diligence, I assume Ryan Propper has probably not done as extensive ECM as they've done in the 5k range. https://www.mersenne.ca/userfactors/ecm/45930/exponent

I only have save files for the exponents in question from either when 100% reporting finished on its own, or I stopped the worker still reporting 100% (thus dumping progress to the save file of said exponents.) Unless you mean other exponents that I took to a certain B1, prior to when I was told how to make Prime95 do only B1 (as in; it was simply skipping stage 2 for those save files) Last fiddled with by lisanderke on 20211217 at 00:40
