As of right now there's still about 4 million in the queue, but they're almost all above 4G, just over 100k left in the 3M range and they should be processed within a couple hours. The bulk factors page may still show a large queue count for a few more days but the impact on everyone's submitted work should be just about past. At least, submitted results should now always be processed within 2-3 hours (probably faster, but I don't want to make too many promises I can't monitor).

Sub-4G factor queue remains empty, the remaining backlog is just above 4G where it won't affect anyone. And I have just cleared out the nonfactor backlog so everything should be pretty much back to normal now. I'll devise a separate queue system for the really-bulk factors once I get back online. Which I'm currently not. After 7.5 days. Amazing.

Wow. I'm back online?! :w00t:

Of course, now that I can see what's going on, I see there are some things that desperately need fixing, so I've taken mersenne.ca down temporarily (less than an hour I hope) while I urgently fix something I broke 2 weeks ago but didn't discover till now, that's causing major slowdowns and broken pages (probably also contributed to the slower-than-it-should-be processing of the factor queue).

I'll put it back online just as soon as I can.

edit: I've put the site back online, just be aware that TF history will be largely missing from site reports for the next day or so as I work around my oops. The data is there, I just need to work on it a bit before you can see it again.

All the major chaos that I'm aware of should now be resolved.

The factor queue is holding steady at under 1 million. I will reduce that if possible, but even if it stays there (or grows) don't worry, I've made adjustments so that larger factors are processed first, and since the mass influx of new factors are all smaller than 55-bit, that means all the "normal" TF results (which are 67-bit or larger) will be processed first. You should always see your results processed within 30 minutes (probably less) from time of submission now.

Thanks for everyone's patience.

Hello everyone, I figured I may as well reveal myself as the factoring maniac that's been hopefully not causing too much headache lately. I've been coordinating with James mostly in PM since I started doing this bulk work. As he's mentioned already, my goal is to TF the full range 1-10G to 55bits, without stopping for found factors. And yes, TJAOI's efforts have been a source of inspiration for this project idea, but also to serve as a general double check which has proven useful already.

I recently downloaded the exports of all factors from mersenne.ca and implemented a filter on my side so that I will no longer submit factors which are already in the db. This cuts down my submissions to the queue by about 5x, or 20% of what they were just days ago. Between that and recent improvements from James, the queue is rapidly returning to 0 again.

In case anyone is curious about my setup, I have 5 different computers working on various ranges, using a specialized PARI script for most of the work. My biggest beasty which I recently upgraded is a dual socket Xeon E5-2697 v2 with 24C/48T and all threads devoted to trial factoring. The other computers are various 4-6 year old boxes which are mostly doing PrimeNet DC tasks, and using the spare hyperthreads on this TF project. I have a few bash scripts to tie it all together, and I wrote the known-factor-filtering program using C++/GMP.

It looks like I've found about 7-8 million new factors so far, with a few thousand of those actually being first time factors on an exponent which were missed one way or another the first time around. A rough estimate is that it should take me another 5-6 months to fully complete this project at my current rates. I also estimate that there should be about 40 million new factors by the end of it :smile:

It appears that the page [URL]https://www.mersenne.ca/manyfactors.php[/URL] does not show the number of Mersenne numbers with 4 factors known.

[QUOTE=alpertron;520951]It appears that the page [URL]https://www.mersenne.ca/manyfactors.php[/URL] does not show the number of Mersenne numbers with 4 factors known.[/QUOTE]No, I removed the 4-factor list a few weeks ago, with all these new factors piling in recently the list was becoming very large. Exponents with 5 known factors are already more than 100k, you can extrapolate that progression to how many 4-factor exponents there would be.

[QUOTE=hansl;520913]Between that and recent improvements from James, the queue is rapidly returning to 0 again.[/QUOTE]It's been a real fight with your "big beasty" vs my little server trying to record the factors faster than you find them, but I think I'm finally victorious! The queue is down to zero! Well, approximately zero; inevitably more factors come in during a processing run, but the queue size should be hovering somewhere around 10k now.

Yeah I had it working on 2G range, but after you asked me to work on >4G, I switched it to 5G range. One side effect of that is that it goes through them ~2.5x faster! (each 2*k*p+1 covers proportionally more of the bit range). Anyways I should be done with the 5G range in a few more days, after which I'll reassign it to lower ranges again, which should slow it down a bit. I'll keep my slower machines on the highest ranges.

Just a rough estimate for comparison... I measured run times here and there between 1G and 4.2G, and getting all the factors up to 64 bits ([C]StopAfterFactor=0[/C]) should take about a year on mfaktc and a single RTX 2080. But of course this would still leave everything above that 32-bit limit untouched.

And you found factors for 3260 exponents that previously didn't have any recorded (mostly due to some data errors I've since fixed). Of course, the higher ranges will complete quicker and so your overall rate will likely slow down a bit (I'm not complaining :wink:), but not bad for a month's work!
