[QUOTE=debrouxl;284774]That's what I used for 1049_67_minus1 (marginally easier than 1061_67_minus1), and it took less than 15h to produce ~2.43M cycles and manipulate them :wink:[/QUOTE]

But I am using a slower processor, probably it will take 48 hours.

Did you (or a script) run with -ncr instead of -nc2?

Nope, -nc. Now it is running. LA ETA of 62 hours!

Mathew, 698419_37_minus1 and 1051_71_minus1 are available to post-process as 479_79_minus1 (28 bits task) but I think the latter still needs more relations.

pinhodecarlos 2012-01-06 11:43

1061_67_minus1 can be moved to to the "postprocessing" state
LA ETA for 1061_67_minus1 is now 21 hours but for 1021_79_minus1 is 69 hours.

pinhodecarlos 2012-01-07 13:55

Taking 479_79_minus1.

[QUOTE=pinhodecarlos;285247]Taking 479_79_minus1.[/QUOTE]

Still needs more relations. I think relations should be increased up to 40M.

frmky 2012-01-07 20:54

[QUOTE=frmky;284461]Worse than that, the gz file is corrupt. I only got 98.5 million valid unique relations from it before the error. gzrecover unfortunately didn't help.[/QUOTE]

I finally had time to take another look at this. Modifying gzrecover to reject extended ascii output and with judicious use of split and tail to avoid zlib segfaults on malformed data, I extracted 157M unique relations from the file. I've started filtering now.

Yay, that was enough.
