If you stop it, you can safely restart it with

nice -19 ./msieve -s L1378.dat -l L1378.log -i L1378.ini -nf L1378.fb -ncr -nc3 -t 4 -v

Or you can wait 90 hours. :smile:

We ran:

[FONT="Courier New"]nice -19 ./msieve -s L1378.dat -l L1378.log -i L1378.ini -nf L1378.fb -nc -t 9 -v[/FONT][/QUOTE]

Just adding the r to -nc will work fine.

[FONT="Courier New"]nice -19 ./msieve -s L1378.dat -l L1378.log -i L1378.ini -nf L1378.fb -ncr -t 4 -v[/FONT]

-nc1 will do just filtering (building the matrix from the rels)
-nc2 will do the matrix
-nc3 will do the part after the matrix
-nc will do all of them
-ncr will resume a matrix

-ncr will do the sqrt as well.

Those virtual cores are getting in the way of progress it seems.

Coping with senility

It's [URL="http://www.imdb.com/title/tt0763029/quotes"]Simpsons[/URL] (Season 4, Episode 16). I even had that as the avatar signature. Aw wait, and then I didn't. Anyway, try the angagramatic aligner:

Really? If so, that differs from the MPI version.

[QUOTE=pinhodecarlos;309133]Can we prove mathematically what is the optimal number of unique relations to build a matrix for a certain number in function of G/SNFS difficulty without spending too much of effort on sieving?[/QUOTE]
I can envision the Feynman defense here.
[B]Theorem[/B]: There exists a distance from which a female looks most [URL="http://en.wikipedia.org/wiki/Physical_attractiveness"]attractive[/URL].
[B]Proof[/B]: At d=0, we cannot see anything so the attractiveness = 0.
At d=∞, it's too far to see anything so the attractiveness = 0.
At 0<d<∞, the attractiveness is a positive smooth function.

P.S. I should quote Wikipedia more often.
No sooner than I quoted the article (but no later than a minute after), it has been vandalized:

[QUOTE]Lionel is The Boss.[/QUOTE]We're going to assume it is okay. If it isn't then we are just out a little CPU time. Sleep eludes us and we need something constructive to do.

Apologies in advance if we are stepping on anyone's toes. We can stop the jobs at any time, no problem.
