Default M929 progress: Sure, drinking kills brain cells - but only the slow ones!

$ wc -l M929.s/snfs.lasieve-1.* | tail -n1

I expect the factorisation of this number to cost me about ten gigajoules (around $400) and take until Christmas.

Pilot was Steven Wright, movie was So I Married An Axe Murderer. Excellent stuff. I'm going to have to have some friends over and watch that now.

But seriously, Tom, are we there yet?

Oh wait, that didn't come out right... I meant, would you need some help sieving? I'd put my 2 percents, and there's probably another dozen guys who would.

Which 5% of the special-q range would you like me to start on?

Siever 15e, -r. I'm seeing CPU times of about 1.5 seconds per Q, though my CPUs whilst copious are slow. Test-sieving suggests that Q=100M-450M ought to be about right.

How about I throw Q=450M downwards open to reservations? You should be able to manage about 5MQ per week running eight threads on an SNB, memory use is 1G virt / 600M real per siever.

Can we start a team sieve on this number with the proper reservation table on the first post?
I want to help but I need some help under linux.
First I need the location of the 64-bit version of Siever 15e and a brief explanation on how to run it under linux (flags, etc). Thank you.

Carlos

Edit. Another thing I remember I need some help, is it possible to start the siever on the startup of linux as on windows? Probably the flags are different. Anyway, I'm trying to search my doubts on the forum.

I am using gnfs-lasieve4I15e 64-bit linux version as compiled by batalov, but I can't find a link to it on the forum at the moment: 'gnfs-lasieve4I15e' is apparently a stopword and unsearchable :( if a red person has the link please update this post to be correct rather than whiny

Example command line is

Code:
gnfs-lasieve4I15e snfs -r -f 123400000 -c 100000 2> 1234.t &
which writes to file snfs.lasieve-1.123400000-123500000. If your computer crashes, do
Code:
gnfs-lasieve4I15e snfs -R -o snfs.lasieve-1.123400000-123500000 -r -f 123400000 -c 100000 2>> 1234.t &
and it should pick up where it left off.

Always use this. It'll correctly handle starting vs resuming.

Is this the right one?

SB: No way - erase it immediately. Its hovercraft is full of eels. I'll build a newest-svn static binary at the oldest kernel machine I will find so that it hopefully would be compatible with most computers.
