[QUOTE=jrk;272404]I posted a poly for this composite earlier in this thread. On August 21.[/QUOTE]Oh.....sorry, I missed it (it has been >30 days after all; I probably saw it but forgot it by now.)

Then, as to the question by debrouxl, do we have enough ECM yet?

That's about half as much ECM as we needed, but if people are willing to sieve already then it's probably OK.

I have just queued some curves @110M too.

600@11e7, no factor.

[QUOTE=Andi47;272929]600@11e7, no factor.[/QUOTE]+200 curves at 110M.

Sorry, I stopped after a couple of days so I could concentrate on a c144 for one of my sequences....

Hmmm.... ECM anyone? If I do the remaining ~4000 curves @11e7 alone, it will take me at least a month or so.

I think you have already wasted longer on ECM than it will take to do the sieving; it'll be about six thousand hours on a 64-bit Linux system, so two weeks on three hex-cores. My machines are busy or I would do it myself.

[QUOTE=henryzz;275248]I have reached the sqrts without a problem. Reducing the memory speed didn't improve things. Should I be altering the settings for the nb(not certain I have access on my rubbish motherboard)? It is a Q6600 in case you haven't realized.
Fortunately Prime95 stability is what I am worried about not msieve stability.

Factors should hopefully be available when I come back from uni today.[/QUOTE]
I have the factors:
prp58 factor: 6154716799577446885023090856129309198086450129268256055737
prp104 factor: 27073317568454671115447910049600122939037137794629195952679986797162648298087899683780597042901407700459

The filtering and postprocessing log is attached. After the first error cost me the first 25% I stopped and restarted creating a checkpoint 2-3 times a day(~8%). Only the one of the restarts had an error on the second attempt and it had somehow created a checkpoint just before.

[QUOTE=fivemack;275506]No factors after 10000@3e7; another 10000@3e7 is running, but I think it's nearing time to start sieving.[/QUOTE]

That's close to a t50. In addition to these, I've done nearly 2/3 of t55 (4857 curves at 26e7). I agree that it's time to sieve.

Ugh. ABORT!
