Can someone share the linux 64 binary of msieve and the rest of the necessary files? Thank you in advance, Carlos.

I would like to test W_2_766 but I need someone to send me the linux version of msieve.

That would be kind: would you mind going for 240M relations? I have plenty of aliquot-sequence numbers to keep the cores busy, and whilst the 210M relations do make a matrix, it's a 17.1M matrix and would take probably ten days.

(I think 240M relations is probably a sensible target in general for these 260-difficulty SNFS)

[/code][/QUOTE]Curious. That's three successive p72 factors.

fivemack, If you want I can do L1247 for you and you can get the credit as well. I use the server from the lab so free electricity.

Carlos: Thanks for your offer, but there's no need. Let the server idle for a while.

On considering cycles to be of equal value
 

I'm being inconsistent with myself.

One thing that I've become really sure of, in doing quite large numbers of factorisations with moderately significant resources, is that the circumstances in which it's worth doing more sieving to make the matrix smaller are rare. Particularly rare if you regard watt-hours as the currency to work in, and even more particularly rare if you regard third parties' watt-hours as worth more than yours.

For example, for 2+947, I spent a month on 56 threads, 700W of equipment in order to make the linear algebra take two weeks less using 12 threads on 200W equipment.

So, if you haven't already pushed more jobs for L1247, don't. It'll take longer even in wall-clock than the time saved, and much longer in terms of coal burned (or, I suppose, water through the Jirau dam). I'll run with the matrix as it is.

Taking GC_9_242 for over the weekend

I've been noticing the fact you use only three cores of your i7/2600. Is it faster than using 4 or you are using one for other job?

[QUOTE=Nooby;372186]Where can I download sieved relations and help with postprocessing?[/QUOTE]

I am going to send you a PM with the email address of Greg Childers. Although a few of us have access to the data for the post-processing jobs I think it is better to ask it directly to Greg. Also on that email tell him the specs of your machines. For the moment you will need at least a 8GB machine for the lasieved integers and 12GB for the lasievee ones. Finally you better don't have bandwidth limitation because each lasieved integer is a download of ~7GB and 13 GB for the lasievee ones.

If I use three cores, then it still makes progress over the weekend even if firefox has stuck at 100% CPU; using -t 4 and then having another job eat one core is a lot slower

Always check this forum for the post-processing reservations and progress.
For 16e jobs you need a cluster (500 cores, 512GB of memory, etc) so concentrate on 14e and 15e ones.

You are correct. Needs at least more 20M raw relations.

GC_12_214 is still being sieved, with ~20M raw relations to be returned yet. I've reserved it for you nevertheless.
GC_5_330 is ready for post-processing.

You are going to fly with your new system.

:bounce: I hope so! I've also got a shiny new [URL="http://www.newegg.com/Product/Product.aspx?Item=N82E16820147248"]SSD[/URL] so I should be able to read and write relations much faster.

I think I have that exact same SSD. It is unbelievable the difference in speed it makes!

[QUOTE=pinhodecarlos;372813]You are going to fly with your new system.[/QUOTE]

Fly indeed. Linear algebra is underway, with an ETA for the whole thing of ~29 hours (currently 27.7% complete with ~21h to go). I set target_density=110, and got a 7.1M matrix.

Just saw on the web page that "Ben Meekins" is recently listed as going to post-process this number.

I've already started linear algebra on this number. If possible, Ben should be informed so that he does not duplicate this work (or inform me if I should abort my run). FWIW, I should finish and report the factors by Saturday morning (i.e. ~2014-05-10 11:00:00 GMT).

Email sent to Lionel and Greg. Keep running GW_4_383, you reserved first.

EDIT: PM sent to Ben Meekins.

Tim, keep going. Received the PM from Ben and I think the moderators just got you real name wrong....lol Ben is not running nothing.

Hi. I didn't reserve GW_4_383 (or I'm getting WAY older and more forgetful than I realize). Tim, it's all yours.

-Ben

Sorry, I mixed up the real names of Mini-Geek and you :smile:
Fixed.

Ok, no harm done. Thanks for getting that straightened out. :smile:

Yeah, no worries. Maybe I'll be back to actually reserve some soon :)

And one much simpler task (SNFS):

C208_133_43

43*(43^22)^6 + 133*(133^7)^6 = 16248239480 * C208

[QUOTE=XYYXF;373225]Still hope :)[/QUOTE]

They're only C168. The sieving time would be about 1000 real-time hours running eight threads on a quad-core Haswell, which is comparable to the amount of time the 18000 ECM curves took. Run them locally.

The SNFS difficulty 220 would take less than two weeks on a quad-core Haswell.

These jobs are too small to be worth distributing.
