[QUOTE=Miszka;512314]Today I found my largest composite factor 19147642464835832222111776488276027610060674573088897824886038321359 (223.5 bits - 68 digits) =82139596673583394582617549419848961 * 233110987151874257840851425095119 for the number of [URL="https://www.mersenne.org/report_exponent/?exp_lo=3146833&exp_hi=&full=1"]M3146833[/URL].[/QUOTE]

Can someone point me to a link of how to calculate the probability of P-1 finding a factor, as well as the GhZ-Day calculation for P-1? If I could figure out how to make a script to identify exponents < 40M which have similarly high likelihood of factors found/GhZ-Day, I might have to throw my home computers on them...

*this is actually pretty out-of-date and needs to be reworked, you may or may not find anything useful there.

Wow, nice one, 158 bits, prime! Congrats!

P-1 found a factor in stage #1, B1=685000.
UID: Jwb52z/Clay, M91131653 has a factor: 169246433448198777407647199 (P-1, B1=685000)

87.129 bits.

320000-360000 range has been completed. 711 exponents were processed and 56 new factors were found. Now i am starting work on 360000-400000 range.


Also I found my first small P-1 factor
P-1 found a factor in stage #2, B1=100000000, B2=2000000000, E=12.
M287939 has a factor: 27265853414344474964957059537 (P-1, B1=100000000, B2=2000000000, E=12)

Impressive

[QUOTE=newalex;510937](...) with a major goal to complete all unfactored <500000 to 30-digits level.[/QUOTE]

I´m gonna help you out with the remaining exponents in the 200k range.

Still, I´ll be much slower than you. Your rig is FAST, man!

yes, these two Xeon Scalable processors are awesome. Each core processes about 350 curves per day for B1=250k in this range.
I appreciate your help. Together we will make it done faster. I plan to work up to 500k first so 200k range is all your for 2-3 months.

My Kaby Lake @3GHz completes ~285/day per core for the same range.

Will be a bit more as soon as the 200k starts. 2 - 3 months will certainly be enough to complete the range.
