I'll do 330340M. (PS: My website/aliquot pages are now on a dedicated server, and so should be less temperamental than the last week. )
Edit: FWIW, here's the script I used to run this job: Code:
#! /bin/bash siever="15e" start=330000000 # qrange start len=10000000 # qrange length cores=4 affin="2 4 8" # Hex, one entry for all but one core (see `man taskset`) a="1" # Hex affin for the last core (not necessarily literally last) diff=$(($len/$cores)) echo "diff: $diff" echo "affin: $a; start: $start" nice n 19 taskset $a ./gnfslasieve4I$siever snfs v R o rels$a.dat r f $start c $diff & let start+=$diff for a in $affin; do # Loops over each spaceseparated substring of $affin echo "affin: $a; start: $start" nice n 19 taskset $a ./gnfslasieve4I$siever snfs v R o rels$a.dat r f $start c $diff 2> $(($start/1000)).t & start=$(($start+$diff)) done If you had 8 cores, you might do something like Code:
affin="1 2 4 8 10 40 80" # Hex, one entry for all but one core (see `man taskset`) a="20" # Hex affin for the last core (not necessarily literally last) Last fiddled with by Dubslow on 20121202 at 10:14

Err, 330340 includes the range that em99010pepe is running: maybe 334 would be a better place to start?
I should finish 360385 in the next couple of days, which might even bring enough relations to finish the job; if not, I'll take 340360.

fivemack, I didn't reserve 330334 so it is free.

360385 finished at 1102 this morning; it didn't give enough relations for a matrix. So I'm starting 340360 now. It'll probably take almost until Christmas (I'm doing a few C159 GNFS jobs for aliquot sequences in parallel); I hope dubslow will have finished 330340 by then.

Won't be done by Christmas
With 330360 merged in, I do get a matrix.
However, it's a Godzillasaurus of the matrix world, with 45.2 million cycles and an expected runtime of 1100 walltime hours on 24 CPUs. So I'll sieve 8095, which should take about 250 walltime hours on 24 CPUs (but I'll use 48) and see how much smaller that makes the matrix. Could I interest anyone else in doing 6080 ?

Thanks to Dubslow for providing 14621712 relations.
I sieved 6070 and 8095, Dubslow sieved 7080. The result was about 51.6 million relations, of which 28.7 million survived uniqification. Code:
driver@tractor:/scratch/M929.l$ grep cycles msieve.log Sun Dec 23 22:23:57 2012 found 45398613 cycles, need 45251317 Sun Dec 23 22:24:40 2012 weight of 45251317 cycles is about 3167856145 (70.01/cycle) Sat Jan 19 09:43:21 2013 found 38739067 cycles, need 38550605 Sat Jan 19 09:43:54 2013 weight of 38550605 cycles is about 2698848446 (70.01/cycle) I'm not sure that really counts as success. It would have advanced the time to completion only very marginally if I'd run on all 48 cores and not performed five quite large linear algebra jobs for NFS@home in the interim. I've started the linear algebra and anticipate results before the end of February.
