Recommended bases and efforts
Below are some recommended bases for testing.

I don't know if it will help you now but attached is a file of the 176 k's remaining at n=2500 for R96. I am now showing the # of k's remaining for each of the new bases in the 1st post at n=2500 with the exception of R108, R192, and S192 that I'm not quite done with yet. I'll attach them to the 1st post as I finish them. Gary Last fiddled with by gd_barnes on 20100325 at 02:57

1. Add an additional file to the zip on my machine. 2. Edit the post to delete the previous attachment and add the new one. Last fiddled with by gd_barnes on 20100325 at 03:39

Well, I guess what I was thinking is if the zip file was on the largish side it would be a pain to have to upload it again each time...though I do suppose the forum's attachment size limit keeps that in check somewhat.

I'll keep that in mind for future reference since it would be slightly easier for the person who needs the info. to have them in separate files and it shouldn't be any more hassle to do it that way. Thanks for the tip.

Tell you whatI'll reserve R181, R182, S140, and S187 to start with, if you don't mind sieving all that. (Note that they wouldn't have to be done all at once; I imagine even one core of your i7 sieving would be enough to keep up with my quad doing PRP if you do them one at a time and send them to me as they're ready.) That should clean up all remaining unreserved bases <200 with one k remaining at 50K, and then all unreserved Sierp. bases < 250 with 2 k's remaining at 25K. Note that in all cases, I'd be stopping at n=100K: that means 50K100K for R181 and R182, and 25K100K for S140 and S187. Last fiddled with by gd_barnes on 20100904 at 04:33 Reason: update status

Thanks for the list. That might be a good list for others to work from also. Concentrating on bases <= 250 is good because all bases <= 250 with CK <= 10K have been or are currently being searched to n=25K. So it's virtually set in stone that there will be no more bases <= 250 with 1 or 2 k's remaining barring some miracle unknown superheavyweight base with CK > 10K that manages to prime all of its k's except 1 or 2. That seems virtually impossible. BTW, I'll make a SWAG estimate at about 12 CPU weeks avg. on these for each k for n=50K100K. So a quad could likely blow through them in 24 days each (for n=50K100K on the 1k bases; add about 20% for each k for n=25K100K). I think the 2 k's that I did for S218 for n=50K100K took about 8 and 9 CPU days respectively. I ran them on one core each. Gary Last fiddled with by gd_barnes on 20100506 at 19:36

Max,
For consistency, I added all 2k & 3k bases <= 250 that are at n<=100K. If you are going to search some 2k & 3k bases that are at 25K to 100K, then we may as well have a list of all of them that are at n<=100K. All of the others were either at 40K or 50K. I also corrected your S133 from 25K to 40K, which prompted the additions. The one that is "most behind" where it should be vs. its neighbors with a similar # of k's remaining is the 2 k's on S72, which are at n=40K. BTW, all of the 1k & 2k bases that you've reserved are already recommended in this thread. These types of bases are the ones that it would be nice to have pushed higher.

I received a sieve file from Mathew for S49 sieved to P=500G. It is now posted on the web pages.

Great! Completion of this and a few other reservations will complete all bases on both sides <=200 with CK<20K to n=25K. I think that will be a significant milestone. Many bases with CK=10K20K have been a large amount of work to get to n=25K. To all, I've added a link to our 1st post in this thread to the posting that contains all bases <= 250 that have either 2 or 3 k's remaining at n<=50K. See it directly below all of the recommended bases. Max originated the post and we are working together to keep it updated. With all 1k bases <= 200 now nearly complete to n=100K, that will be a good place to look for work. Perhaps we'll end up with a few more 1k (or proven) bases. :) Another place to look would be in the 1k thread to extend all of those bases 200250 to n=100K. Gary
