Taking 12p11_253 in a day or so when the sieving is finished

[QUOTE=fivemack;518111]Taking 12m5_253 in a day or so when the sieving is finished[/QUOTE]

Speaking of finishing sieving, what exactly is going on with 12m5_253? I'm used to seeing work units not quite add up for a while, but by the end of the job they usually get accounted for, with maybe one or two going missing (e.g. see 105__363_5m1, which seems to be short by one).

But 12m5_253 has over 500 work units that seem to have disappeared. Does anyone know how the server's accounting works, and what may have gone wrong here? Given the high duplicate rate I've been seeing for recent jobs, that missing work could really matter for this number.

Three hours on 10 cores Xeon Silver 4114 VBITS=256 for 4.02M matrix at density 136 (not 138) - it took longer to run the filtering on a rather busy machine than to solve the matrix.

is an absurd level of oversieving for numbers which are this easy, the clique removal is taking half as long as the whole linear algebra job.

I re-calculated the estimated yield and came up with similar numbers as NFS@home posted. I must have made a math error along the way. Yes, it was well over-sieved.

I am happy if I can solve a 31-bit job in under a week using my Sandy Bridge core-i5 boxes. Or 32-bit jobs in under 2.5 weeks. I would like to upgrade to xxxDECA-core system but I'm not that familiar with liquid cooled systems.

I used liquid cooling on my i9-7940X for a while, but basically it's not integrated enough with the motherboard to make sense (that is, if the liquid cooling fails you don't get anything resembling useful alerts in system logs, you just see a temperature increase and mysterious power-downs); I've switched to a Noctua NH-U9S now and it's been fine for a year.

I am very confused - my post [url]https://mersenneforum.org/showpost.php?p=518111&postcount=379[/url] says I'm taking 12p11_253, but your quote of it [url]https://mersenneforum.org/showpost.php?p=518146&postcount=380[/url] says 12m5_253. I am half inclined to take 12m5_253 too, and half inclined to see your post as a reservation of 12m5_253 in rather peculiar form. Please advise.
