[QUOTE=bsquared;235091]I'll finish up 77-80. I think we should have plenty of relations for a matrix, the only question is how big it will be. If you post the log file after running the filtering step, we can comment on it then.

I can probably build a binary for you too, if necessary. What platform (windows, linux, 32, 64 bit) are you on?[/QUOTE]

Windows 7 64 bit. Please compile it with large blocks, TD=80.

I've put the exe on my [URL="http://sites.google.com/site/bbuhrow/home/factorization-code-links"]webpage[/URL].

Also, here is some more data
[URL="http://www.sendspace.com/file/xg2xv0"]77-79M[/URL]: 2871211 relations

Thank you. Do you think we should increase target density to 100 for this case?

I don't know... I've been out of the running-giant-postprocessing-step game for too long to know what the tradeoffs and breakpoints are.

Let's wait for Batalov or Greg's reply. They are the experts. Anyway, I just need one more day or less to finish a RPS range to start post-processing this integer.

Sounds good. I can get the last 1M range done by tomorrow morning (roughly 18hrs from now).

Great! By tomorrow at this time we should have the post-processing running.

Let's see what kind of matrix we get.

ETA will reduce as soon as I get home and overclock the CPU from 3.4 GHz (stable for LLR) to 3.7 GHz (stable for msieve).

ETA now is 141 hours. Expect factors on 08 Nov 10.
