[QUOTE=fivemack;483746]Looks like a missing space in the polynomial file has caused the .ini file not to be constructed. Resubmitted.[/QUOTE]

Odd that space but thank you for correcting it.

[QUOTE=swellman;470027]Houston, we have a problem. Acting on Fivemack’s expert advice, I finally got the above procedure to work on my Win 7 box (via Cygwin) and it chewed on the file for less than 10 minutes. The uncompressed “dirty” file was 72Gb, the new clean data file was 2.4 Gb. Feeding it into msieve revealed barely 20M relations residing in the data file, and filtering quickly terminated. :max:

Either I need something else in my egrep syntax, or that data file is in bad shape.

Where to go from here?[/QUOTE]

You need the -a parameter on egrep, otherwise it will stop as soon as it notices obviously non-textual data in the file and the output will end simply 'binary file msieve.dat matches'. Discovered that just now when filtering 3366.2180

C195_3366_2180 progress
 
[code]
weight of 64591916 cycles is about 4521521435 (70.00/cycle)

:busy:

I've thrown it back for another two hundred million raw relations

Reserving 134^73+73^134 C177 cofactor (corrected run) on 15e

C191 from Phi_5(largest_factor(Phi_23(1009))) update
 
Filtering with TD=120, 110 and 100 failed (I might have been a bit too optimistic)
But TD=90 produced a very do-able matrix:
[code]linear algebra completed 298470 of 13431670 dimensions (2.2%, ETA 125h42m)[/code]So it should be done in about a week.

Would someone advise the file name for this number?
