[QUOTE=debrouxl;435231]C188_132_125 has terrible yield: after sieving most of the 20M-120M range, the recommended ending Q is currently 1487M, which is [i]way[/i] too high.
32-bit LPs are usually alright for 15e on a number of that size, but qlim = alim = 26800000 is an order of magnitude too low. I failed to detect that when pasting the ready-made polynomial. I guess we should terminate sieving for that number, and create a new entry with the fixed polynomial ?[/QUOTE]

Good catch - looks like a typo for 268000000 (round number just less than 2^28). Yes: terminate sieving, delete the job and start a new one. Bother.

I originally suggested the value of alim=268M, so I'll own the error. What should it be? Models I've seen suggest ~362M, but I think you guys are implying it should much higher.

Is this due to 3 lp vs 2? Or something else?

No, the problem is that alim was typoed as 26.8 million, which is clearly too low! 268M is about right (just below a power of two is good because of the internal architecture of the siever)

Understood. Well, this gets better as it was my typo that Lionel used for the 15e job. :max: Sorry for the wasted cycles everyone.

A few more candidates
 

Just in time for the upcoming decathlon. Polys attached.

Trying to hit the sweet spot for 15e: I have a 182-digit composite (HCN) that would be SNFS-271, so it's right on the edge between GNFS and SNFS. It's received a full t55. How much additional ECM would you like to see before it can be queued?

Given the state of the queue I'd happily queue that number without further ECM.

Okay, the number is 6^347+5^347. Polynomial below. Sorry, I don't know typical parameters for numbers at this difficulty.

OK, parameter selection running overnight and I'll queue it in the morning.

Will also do parameter selection on Gimarel's polynomials at [url]http://mersenneforum.org/showpost.php?p=435354&postcount=631[/url] and queue the best one

6+5.347 queued

14e management page should be updated because a lot has been done for more than a week without being reflected on the page. Thank you all.
