77 hours on 7 threads E5-2650v2 for a 13.1M matrix. Log attached and at [url]http://pastebin.com/ftSGyXDq[/url]

(fx: bites bullet; grimaces)

Taking C193_143_93. Anticipating it will take a couple of months.

[QUOTE=fivemack;455020]The last 33-bit job I did took nine weeks on a 32GB i7/5820K, which has two more cores and a significantly better memory subsystem, and is in a water-cooled desktop machine that ran unattended 24/7. It used more than 20GB of memory for the nine weeks.

I think probably you'd be biting off more than you can chew.[/QUOTE]

How long would you expect these to take on the Knight's Landing system?

[QUOTE=swellman;454831]I'll take C172_327668647153_19 once sieving is complete.[/QUOTE]

C250_51119
 

Would it be possible to run some additional sieving on C250_51119? I'm struggling to get the matrix to build. Than you.

Another 25% queued up for C250_51119; should be a nice small matrix when that's done.

Thank you!

There's some odd data corruption going on with C193_143_93; if I just use gunzip then it stops after 1126400417 decompressed bytes with

[code]
gzip: C193_143_93.dat.gz: invalid compressed data--crc error

gzip: C193_143_93.dat.gz: invalid compressed data--length error
[/code]

Thankfully gzrecover exists; the result from it is quite full of corrupt patches, but
[code]
egrep -a -e "^[0-9-]+,[0-9]+:[0-9a-fA-F,:]+$" msieve.dat > msieve.dat.clean
[/code]

cleans it up a bit. I don't think it can be getting damaged in transmission - I'm downloading over https, after all. Should be able to proceed regardless, it looks as if there are a billion clean relations there.
