I'll expect even more CPU power running NFS@Home Challenge Part 2. 16e and 16e V5 wu's availability are safe, I don't say the same for the 14e and 15e ones. Expected daily points of 3-4M.

You have been warned....lol

More 14e Lattice Sieve wu's are needed. Greg, you need to have a 14e buffer like the one you have for the 16e wu's. There's a French cruncher with 180 computers ( i5-2400) with only 4GB of memory each that only runs the 14e and 15e wu's.

Isn't there away to create the wu's offline the server?! People could help you out.

PS( Sorry for spamming your email address and post a lot here about the challenge/wu queue, etc)

Hey [URL="http://www.mersenneforum.org/member.php?u=3"]Xyzzy[/URL],

As the second part of the NFS@Home challenge is going on the 14e wu's are being done at a daily rate of Q range of 153M. This means that daily almost (50 %) of a 31-bits LP task is being sieved or 80% of one 30-bits LP task sieved daily.
You sold your machines at the wrong time...lol
Tremendous CPU power in the house.

If, by some weird chance, the world does not end, we will just queue the work up. It will get done eventually.

How much memory and time is needed for a 30-bit LP job?

[QUOTE=henryzz;322069]How much memory and time is needed for a 30-bit LP job?[/QUOTE]

4GB. Time depends on the final size of the matrix and on the processor used (nº of cores).

I can do a 30-bit on my 4 GB Q6600 if necessary then.

With your machine you can easily do 313549_37_minus1 and 413588356833933793_13_minus1. Both are 29-bit LP tasks. These two are almost sieved, one more day and talk to Greg to give you access to the server.

Look at Est. Pending Rels column, if it gets below 600000 you can start the post-processing phase.

[QUOTE=henryzz;322069]How much memory and time is needed for a 30-bit LP job?[/QUOTE]

Obviously depends on the hardware you have to throw at it. Two to three days on four threads of i7-class, about 4G memory. Fifteen hours on 24 cores K10/1900 MPI, rather more memory. Five to six days on four threads of Q6600.

31-bit LP jobs are 40 to 60 hours on 24 cores K10/1900 MPI.

Do you need a hand with any of the 31-bit LA jobs?
