[QUOTE=Prime95;348466]Is that a GIMPS P-1 record?[/QUOTE]
Most likely not. [url]http://www.mersenne.ca/exponent.php?exponentdetails=17504141[/url]
Seems like a good candidate for that title. 148.257 bits, slightly larger 45 digit prime. (It is largest reported between 10M and 100M)

P-1 found a factor in stage #1, B1=755000.
UID: Jwb52z/Clay, M69601027 has a factor: 1404142018250675959530553

332312179 has a factor of 14210518201851118532927. I ran it from 61 to 64 one day in 2009, came back months later, ran it to 66, a month after that ran it to 67, months after that, took it to 70. After some other folks touched it over the years, I worked on it again and found the factor at 73.6 bits.

P-1 found a factor in stage #1, B1=725000.

Not sure if this thread is for this type of work, but I am happy about my 20th factor in this range. If it's not welcome say so and I'll refrain from posting further.

It's definitely welcome here, and so is your effort on these (or any) exponents! The more factors the better, and these are "premium" assignments (can't run mfaktc 0.20 on them, making them pure CPU)

Full of envy :razz:, and channeling my inner RDS: if that was CPU work, then it is a big CPU resources waste... Except if they were done on very (but I mean VERY) old hardware that can't do LL nor DC and neither it has enough RAM to do P-1. Which I don't believe, given the (very) short time it took, two months for 2k assignments, at such low exponent, "mid to top" range CPU was used. Or more small machines, but with just a cheap stick of RAM (novadays) you can use that old hardware more efficient (doing P-1 or factoring aliquots).

From the time spent, you may have a mid-top-range GPU and you used normal mfaktc/o, in which case I congratulate you! (@clocker: please be advised that those are exponents over 1 million, therefore in the range of normal mfaktX programs).

OTOH, if you like to do quite low-expo assignments, you can ask Oliver for the "bcp" version, which can TF expos from 2k to 1M (most of them at 61-62 bits right now). Actually, that would also be a a waste, due to the huge amount of ECM done to such exponents, theoretically they won't have any factors below 150 bits or so (50 decimal digits).

Sorry, I should have been more clear. They can't harness the major boost of GPU sieving is what I should have said. 24 GHD/Day on these vs. 146 GHD/Day for more aptly suited assignments on my 460.
