I've started running a script to add algebraic factors where they exist to factordb. I'm currently working from 88 to 90 digits. Which should thin down the junk a bit.
But this is getting rather annoying. Chris

This is what frustrates me away from providing my external elves. Currently, I'm hitting back pretty hard with a bunch of systems running from 70dd(+10) upwards. I'm showing a rate of a little over 6k/hr factored. I also have a couple Colab sessions working the same region.
In addition, I've got some RPi's and a separate Colab session working in the 40dd range to see what that does.

Actually, it looks like for >69dd, we've caught back up to yesterday.
Am I treading on your algebraic factor work, Chris?

It's gone to >1M <70 digit composites!

I have been running in the 40dd and 50dd to find where my C2D laptop won't bust the hourly limits. It seems these number all have at least 1012 or more factors!

That explains why my Colab sessions weren't factoring 100%. I didn't look into why, but either YAFU wasn't returning factors less than 5 or 6 digits in size or my Python code wasn't retrieving them.

Thank you! Because of what you posted, I revisited my RPi's that are only doing ECM. They had been registering <50% success in factoring, which seemed odd. I was starting the ECM runs with B1=11e2 and stopping with 11e5. I changed my start B1 to 11e1 and now I'm showing better than 90% success with composites at 10 digits + 100 (offset).

No, I've stopped that (there don't seem to be any left in this range).
Looking at a few in the 70+ digit range most of them seem to be from factordb running ECM against a large number and finding a composite factor (the product of most/all of the small factors). Just click "More information" and see what it says it's a factor of. It's probably true for the under 70 digit range as well. I'm currently adding algebraic factors to numbers with status unknown. At present they nearly all seem to have algebraic factors. Just look at http://factordb.com/listtype.php?t=2 And I think the limits have been raised recently. Which is just as well given my 1 PC working from 70 to 79 digits seems to be factoring about 1 number per second! Chris

If you have GP installed try something like:
Code:
echo 'factor($n,10^5)'  gp f q Chris

Well, I've given up for now! I can't make my "farm" machines keep running for some reason. They all start out fine, but then spew junk after a few iterations. I guess the overwhelming small factors are somehow wrecking something. . .
I have the RPi's working in the 79dd+10 range, but nothing else. No Colab instances, either.
