Sieve special_q on -a side from 20M to 66M using siever 14e. (A nice task for RSALS?...)

(I'll continue poly selection for awhile until sieving starts)

I'll offer to post-process it in case sieve goes to RSALS.

Pointed my cores to schickel's ecmserver. Before starting with this number I found a factor for the previous work the server was handling. I don't know if it is related to Aliquot search. Frank, please check your logs.

Andi47 2011-02-19 11:34

p-1: B1=1e9, B2=1e14, no factor

Edit: Just in case that someone wants to extend this bounds, the savefile reads:

[code]METHOD=P-1; B1=1000000000; N=75932340428877011727618708726905558562515248304152927449065726063130564403655850880406162753916607273084882142223225126840338325892660195804478997023817401; X=0x1f016dc25c94263f9e81480e52c5320b9dce0c152c830d2897a626e79aed125e9a00693ef39a0a8937d6021480e57875d54d9d20e4de31de6a2c558244c4545a0;

Yeah, RSALS was born to factor C154-C155 semiprimes, and we have lots of clients at the moment, so we could easily do it entirely.

But as usual, we don't want to stomp on individuals' toes. There's even more room for other participants this time than the previous sequence 4788 sieving which RSALS ended up doing entirely, since the number is noticeably shorter :smile:
One thing that other participants can provide, while RSALS cannot, is ranges without holes: the "long tail" effect of small scattered holes easily persists for 3-5 days.

em99010pepe 2011-02-19 18:03

~1006 B1=43e6 curves but Frank will tell us the right number...

bchaffin 2011-02-19 18:23

I'm up to:
4300 @ 40M
2125 @ 43M
800 @ 100M

Including previous posts, I think that puts us at nearly 9500 curves at 40-43M, plus 800 more at 100M.

I've now found a couple polys, the best of which is
# norm 4.025205e-15 alpha -7.671371 e 2.488e-12 rroots 3
Is it about time to start gnfs?

unconnected 2011-02-19 18:42

Small effort from me: 1000@43e6 and 500@11e7.

Andi47 2011-02-19 19:13

~420@43, no factor. Same with 3*p-1 at B1=1e9, B2=1e14
