146.5 hours for 16.83M density-136 (138 didn't work) matrix on 7 cores E5-2650v2. Log attached and at [url]https://pastebin.com/Qd4ZDnBu[/url]

[QUOTE=frmky;470028]Looking at it now...

Edit: now download the "clean" version and try again.[/QUOTE]

It works! Downloaded the data file and it was clean, no problems noted. Thank you Greg! Did you find the source of the recent data file corruption problems?

This morning I noted that this 14e/33 msieve job successfully built a matrix from 697M raw relations @TD=70, ETA 2450 hrs. Going to try again at TD=90.

[QUOTE=fivemack;470008]Yes, egrep doesn't work on compressed data. But if you're on a Unix machine, gunzip -c msieve.dat.gz | egrep ... | gzip -c will filter the compressed relations file on the fly and recompress the results as they come out, which ought to save quite a lot of disc space.[/QUOTE]

Just a followup that this worked perfectly, and the matrix is now built and due to be finished in ~80-82 hours.

I'll have a go at LA for Lucas(3795) from the 15e queue.

I see this number is assigned to Greg now; I hadn't downloaded relations yet, so I'll process L5715A from the 14e queue instead.

Took approximately 93 hours on 8 threads of a 4930K at TD=130. Log file is attached. Note that I removed all the bits of the log from when I was having issues with the initial relations file.
