Default Team sieve #41: C165 from 3366:i2098

Tracking Aliquot Sequence 3366 index 2098.

Poly generated by sashamkrt
Post-processing by: ???

Run the siever using the following command:
Code:
gnfs-lasieve4I15e -a 3366_2098.poly -o <output_file_name> -f <start_of_range> -c <length_of_range>
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'm not sure how much to take. I can do 1M in under a week. Is 2M okay?

If so, I'll take 18M-20M.

20M-22M are on SendSpace:

3366i2098_20M-21M.rels.zip
3366i2098_21M-22M.rels.zip

I had a lot of trouble with this task. 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.

22M-24M are on SendSpace:

3366i2098_22M-23M.rels.zip
3366i2098_23M-24M.rels.zip

They have been run through remdups4 and show as 4440508 and 4432062 unique, respectively. remdups4 showed a total of 81892 duplicates.

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. :)

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...
