150@11e6, no factor

bchaffin 2010-11-23 02:08

I ran 2350@3e6, 4480@11e6, and ~2000@43e6 with no luck. I just killed polyfind and started sieving.

c143 is done and in the DB, and the next term fell quickly with ecm. It decreased both times, still with 2^6. Next up is another c138...

are you sieving or still running curves?

Still running curves. Just finished 904@1e6 and 2350@3e6, running some @11e6 now.

I'm running polyfind in parallel but so far it hasn't found a single one so it will be a while before I can start sieving.

running 1500 curves a 11e6,will be done in 12 hours.

Just finished 4490 @ 11e6, and about 150 @ 43e6. Polyfind is making some progress (48 found so far) so I'll probably give it another 4-5 hours (until bedtime) and then start sieving if nobody cracks it with ecm first.

Yeah, I did ~850 @ 43M before cutting it off and starting the sieving. Up to about 18M relations now, so hopefully it will be done some time this afternoon/evening.

The c138 is done, along with four more terms that fell pretty quickly (one with a 45-digit ecm factor, that was nice). The last few terms have grown quickly with 2^7 * 7.

Unfortunately the next term has a c167. I've done 74@11k, 214@50k, 430@250k, 904@1M, 2350@3M, and 4480@11M. I've also run polyfind for ~12 hours, with nothing found so far.

For now I'll leave polyfind running and continue on to some curves @43M, but obviously if gnfs is required this is beyond me.
