Team sieve #30: c156 from 283752:i7004
In the spirit of giving everyone something to keep them busy....
283752 is currently being driven by 2^3 * 3. However, 7004 is the 16th line with the driver having the form 2^3 * 3^2; accordingly, there is a 50% chance of an escape on the next line. unconnected reported doing 1.5*t55 worth of ECM work and LaurV performed the poly search. ====================================== Got a poly after about a week. Is it (relatively) good? How good? How long the sieving will take on two cores of a core2 3Gigs? (about) Can that be taken as a "one man job?" Maybe I will give it a try.... Code:
# Sieve with the 14e siever on the algrebraic side starting from 15M # Target is 56M raw relations n: 150334450606011724019777200211010468220565590046299234402254345532711750018652367487259651931850319063498312781804011647293058067263942651704486104870980321 skew: 14230655.24 c0: 520134197785689262516595081751266984241 c1: 809982347485060642501973343231813 c2: 321021768654971361269241683 c3: 4637554577292436357 c4: 1395390947346 c5: 17040 Y0: 1545689251703330366629739901868 Y1: 956597419325010283 rlim: 30000000 alim: 30000000 lpbr: 29 lpba: 29 mfbr: 58 mfba: 58 rlambda: 2.500000 alambda: 2.500000 Code:

Yes that is a good poly. My expected murphy score for a number of this size is about 2.71e12 and your poly is 2.81e12, so that is good. You should use ggnfs siever 14e and sieve on the a side starting from specialq 15M until you have gathered 56M raw relations. Sieving will take about 3 to 4 weeks on your two cores, and the matrix about 2 days using msieve.

OK, so just to double down on everything, how about another team job?

I can do the postprocessing. It would be a good test for my computer now I have sorted the memory problems.

OK, sounds good. I'm in the final stages of a c153; ETA for completing sieving is Monday at the latest. I'll start sieving on this after that..... My c153 is going at ~3.5M rels/day, so I'm not exactly a speed demon.

I guess I'll take 2025M, too.

I'll also offer to do the post processing... if you still want it henryzz, say the word and I'll upload my relations. otherwise, I'll grab schickel's and finish it. Last fiddled with by bsquared on 20111113 at 14:46

And, if possible, I had only just started hitting the 20M+ range, so it might pay to run the 2125M range if you can....
