[quote=schickel;171122]I'll put it in to run some curves @ 43e6, but I don't know how long before my heavy duty worker contacts my server (2 hour contact interval); my light duty worker connects at a 15 minute interval....[/quote]
Are you sure it needs anything at 43e6? I was thinking that the worker's default of a full t40 would be plenty (considering that it was enough for a c132).

I will start a poly search for this c131.

jrk 2009-04-28 04:12

Shall we make this another team factoring run?

Best poly found so far for c131 (still searching):

Well, considering that our earlier C132 only would have taken about 4-5 days, tops, on a reasonably-modern quad-core, a team sieve on a C131 may well end up oversieving it so humongously that we have a hard time doing the postprocessing. :smile: Thus, it would be ideal if an individual is interested in doing all of the sieving on this. However, if nobody's interested in going it alone, then of course a team sieve is still workable (though this time we'd have to be especially careful not to oversieve too much). I can volunteer for the postprocessing again if nobody else is particularly keen on doing it. :smile:

The t40 is still nowhere near completion because someone clicked "Stop" on it to make progress on another number.

Thats the reason i don't run my workers anymore

[QUOTE=smh;171257]Thats the reason i don't run my workers anymore[/QUOTE]
I understand you so well. A queue is a queue is a queue. Unless some rowdy comes and says "Me first". ( I plead guilty, but only once or twice, after waiting two days for my number). While the thing that new jobs get priority is a good thing at low levels, one should not be able to influence the queue for the B1=250000 and 1000000 level. Definitely deserves fixing. H.

I did P-1 with B1=1e9, B2=1e14, no factor. I started P+1 with the same B1 and B2 bounds (3 runs)

P+1 done, no factor found.

[QUOTE=hhh;171262]A queue is a queue is a queue.[/QUOTE]

Yes, but....

In the database, any new "very high ECM" factorization is queued first (So it's NOT a queue, as in a normal queue, newly arrived persons or things are queued on the LAST position). So if the DB's "queue" a number will have to wait *forever* if the "queue" keeps growing. This increases the temptation to click the "run now" button - and IMHO this needs to be fixed.

I would suggest to:

either queue any new number to at the *end* of the queue as soon as it has been "prepared for very high ecm" (i.e. p+/-1'ed, IIRC)

or run *only* the 25 digits level (i.e. 200 curves at B1=5e4), and THEN put it at the *end* of the queue.

In this case, for example a composite which is queued in 4th position WILL be ECMed as soon as the first three composites are done, and not at [URL="http://en.wikipedia.org/wiki/Saint_Glinglin"]St. Glinglin's day[/URL].
