The factors appeared thanks to msieve SVN r965, but the invocation was the same for both the faulty msieve SVN r966 runs (different target densities) and the successful msieve SVN r965 run:
[code]ionice -c3 ~/msieve/msieve -i GC_2_757.ini -s GC_2_757.dat.gz -nf GC_2_757.fb -nc target_density=90 -v -t 4[/code]

Tonight, with msieve SVN r967 invoked the same way as before, filtering the original raw dataset for (G)C_2_757 succeeded, discarding 53 composite relations. LA has now successfully started as well, currently at ~0.3% with ~42h ETA, I'll let it run at least until tomorrow morning.

Log is attached. It took right at a week, as expected. The memory usage for most of the LA was around 10.4 GB.

Just a quick note. For Fibonacci and Lucas Factorizations please send an email to Marin Mersennus so he can update the tables (4 are already missing, the ones processed by Thomas Womack).

I think it is time to my a little guide (sticky thread) to whom post-processing guys should send an email with factors after submitting the factors to [URL]http://factordb.com/[/URL].
Something like:

Fibonacci and Lucas Factorizations - Send factors by email to Marin Mersennus at marin dot mersennus at gmail dot com

Cullen and Woodall Factorizations (GCW)- Send factors by email to Paul Leyland at paul at leyland dot vispa dot com

XYYXF Factorizations - Send factors by email to YYY

Aliquot Factorizations - Send factors by email to ZZZ

OddPerfect Factorizations - Send factors by email to William

etc

34.5 hours for 8.6M matrix (target_density=120) on i7/4930K -t6 with svn952

Log at [url]http://pastebin.com/Kk1VtmQ2[/url] ; it took eleven dependencies to get a nontrivial square root

With 455.1 million relations, it was also possible to run target_density=150, which gave an 8.0M matrix. Running it for a couple of hours at -t 6 suggested that a full run would take about 35 hours, which sounds as if we may have gone through the optimum density.

51.5 hours for 7.9M matrix on i7/2600 -t3

I am tempted to take GC_7_292 and GC_3_516, download the current data, and throw 48 cores of Opteron at doing a bit more sieving with 15e and probably 3LP down at Q~100M to get the yield up a bit. I think that's a better use of electricity than continuing sieving with the current amazingly low yields.

debrouxl and frmky, would you be OK with this?

2340.672 should be done Monday evening

No objection from me on the plan you've outlined in your post from yesterday evening, I've reserved GC_7_292 and GC_3_516 for you.
Sieving for GC_3_516 was done up to "only" 340M for now, so we [i]could[/i] probably still get a matrix with 14e alone, without having to sieve to such heights as the current 480M for GC_7_292.

I'll take GC_4_410 if it's available, once sieving is complete.

I'll grab C169_123_109 once sieving is completed.

Eta for GC_4_410 is next Wednesday.
