Team sieve #43: C164 from 4788:i5194  FINISHED
Tracking Aliquot Sequence 4788 index 5194.
Code:
# sieve with ggnfs lasieve4I14e on the a side from 30M to 114M # aq4788:5194 n: 56336747150380626438276754902488766416020903744837900647138061605999767753078104418680167689142175489355492712257458624526631830323402854770850021959017408855080521 # size 5.496e016, alpha 7.363, combined = 7.985e013 rroots = 3 skew: 111313596.81 c0: 2904896119859058264406991009861093144150400 c1: 64638219915023936469554866040149272 c2: 3017144413645332474429006886 c3: 20234230792711171585 c4: 171065306604 c5: 432 Y0: 167132767303944628800670041934723 Y1: 262569407971517 rlim: 60000000 alim: 60000000 lpbr: 31 lpba: 31 mfbr: 62 mfba: 62 rlambda: 2.6 alambda: 2.6 Postprocessing by: ??? Run the siever using the following command: Code:
gnfslasieve4I14e a 4788_5194.poly o <output_file_name> f <start_of_range> c <length_of_range> (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., 42M = 42000000) 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 4788_42M.rels as signifying the starting point. The output files can be placed at any of the file sharing services: DropBox, RapidShare, SendSpace, etc. To start things off I'll take 3038M.

There was a slight improvement to get a 30bit job using 3LP but it needed the 15e siever. This would have removed NFS@H from the mix should they decide to jump in. Last fiddled with by RichD on 20140110 at 01:05 Reason: add "would have"

I have never done this before, but I would like to have a go.
I have no idea how long this is going to take so is 1M a good start? If so then I'll take 3839M Edit: Ok I'm guessing I'm doing something wrong. I'm starting with: gnfslasieve4I14e a 4788_5194.poly o 4788_5194_38_39.txt f 38000000 c 1000000 v After that it outputs: Warning: lowering FB_bound to 37999999. FBsize 2320767+0 (deg 5), 3562113+0 (deg 1) And then it crashes. Maybe my version is too old? The date stamp is from 2009 (Found a zip file on my system with svn version 374). If so, where can I get a newer version? This version is the one used by Yafu btw. Last fiddled with by Wick on 20140110 at 09:39

Ok I have it working I think.
Downloading new version of ggnfs and reordering the parameters made it work (I think) output: Code:
gnfslasieve4I14e o 4788_5194_38_39.txt f 38000000 c 1000000 v a 4788_5194.poly gnfslasieve4I14e (with asm64): L1_BITS=15, SVN $Revision$ Warning: lowering FB_bound to 37999999. FBsize 2320767+0 (deg 5), 3562113+0 (deg 1) total yield: 189, q=38000107 (0.06913 sec/rel; ETA 33h36m)

I take all the rest. And I will finish the algebra.

It is done. The driver changed into 2^{5} · 3^{2}, only to come back two iterations later.
The size is now 188, the cofactor is c178 and it is ~t50'd. If there's still interest in this sequence, go on with more 110e6 curves.
