If you're wondering why 130396 is still lounging around at 108 digits, it is mainly because of big composites (well, big relative to 108 digits). Some sequences don't get many, even with a slow driver like 2*3. In only about 100 lines since reaching 100 digits, it's had a c105, a c104, a c102, a c101, two c99s (three if ECM doesn't crack the one it's on now), and two c96s.

Even worse, they're really packing it in - I seem to be getting one every 6 or 7 lines right now.

A stark contrast to 10212, which didn't have the fastest of drivers but didn't reach a c>100 until it was at about 115 digits. I hope there's a gap soon (and a driver escape).

Anyone have an idea how unlcuky that is (or have I just not noticed the ones that hit eight c105s before reaching c110 with a driver)?

+400 @11e6 curves.

bsquared · 2009-07-21, 13:52

2000 curves at 43M done.

In doing so, you "gatesed" the workers (remember that occasion)...

..but these curves are real, so it doesn't matter.

I remember someone reporting false curves under that name, yeah

. But does reporting work affect the workers behavior?

Yes. Once the DB sees that enough work has been reported, it takes the number out of the VHL queue. I don't see any problem with what just happened. 2000 curves at B1=43e6 should eliminate or greatly reduce the need for ~1250 more curves at B1=3e6 (what the DB would have run had it continued).

Huh, didn't know that.... learn something every day! Thanks.

I can make up for those lost DB curves tonight with another couple thousand at 43M.

Me thinks we should start poly searching after those are done.

I suggest ~8000 curves at 43M. Poly search can be started even now, but sieving should wait till the full t50 ECM.

Greebley · 2009-07-21, 15:56

My 15 attempts at 110M all failed. Not that this is significant compared to the rest but I thought I would report it anyway.

Wouldn't it be more efficient to finish all ECM, then do all poly search, then all sieving, then all filtering, instead of letting them overlap?
