Run the siever using the following command: Code: gnfs-lasieve4I15e -a 3366_2098.poly -o -f -c  Add the -v switch if you want to see status updates every few seconds. (I like to watch the progress.) In case a restart is needed in the range, add the -R switch. (All range numbers must be full decimal representations. i.e., 21M = 21000000) Since ggnfs is single thread, multiple copies need to be run at the same time to utilize multiple cores. Be sure to use a different output_file_name for each range. Something like 3408_22M as signifying the starting point. The output files can be placed at any of the file sharing services: DropBox, RapidShare, SendSpace, etc. This is a nice poly. Expect yields greater than 4:1 in some regions. To start things off I'll take 14-18M.

I can do the post-processing.

Half of my machines segfaulted out of the sieving. I think everything is cleaned up, but you might want to test them separately. They have been run through remdups4 and show as 4521249 and 4522756 unique, respectively. remdups4 showed a total of 90445 duplicates. I'll run 22M-24M.

Wow, that is fast!
I'm not even at the half way point.

Since I seem to be going along well, I'll run 24M-26M. How many relations are we shooting for? I seem to work it out to about 93M relations needed for a c165. But, I only see about 58M coming from the range we're working. Am I that far off?

I was thinking mid-50's for total rels. We might be able to build a matrix after Q=26M but I added an extra one for good measure. (It may not be needed.)

I'm at 72% with 4.8:1 yield.

You're right EdH. Since the last few were a 29-bit problem I was thinking 29-bit. This is a 30-bit problem so we need nearly twice as many. Maybe a little over 100M to be safe. My mistake.

Edit: So we have to go to Q=40 or 42M (or more?).
Another week and a half. :)

There's a mistake with the first link....

I got the second one, though....

 2013-11-17, 14:59 #11 EdH     "Ed Hall" Dec 2009 Adirondack Mtns 2·7·239 Posts Sorry about that! The correct link should be: http://www.sendspace.com/file/uep62s I will repost all the (hopefully correct) links in my next set of rels...
