New sieve files as of 20150415
Sieve files for k*2^n1
Here are the latest sieve files for 4 < k < 10000 and n < 12M. pmin and pmax give a range of what's been completed. We kindly ask that srsieve AND psieve be credited with any primes found with these sieve files. Those are the two sieve programs used in the sieve. Should anyone wish to credit the effort (PrimeGrid) that is perfectly fine, but certainly NOT required. Active Sieves rsp7M_20150415.abcd  (144,383,287 terms) p~87P Suspended Sieves rsp1M_20110731.abcd  (145,973,485 terms) p=100P

There are still numerous (differences of) squares in these files and other higher trivial powers.
There always have been, and after quite a few discussion, they are still there. Take for example k=9 (566 squares in rsp5M file), k=81 (369 squares in rsp5M file), k=27 (790 cubes in rsp5M file), and so on. I can send you cleaned up files  contact me by email, ok? I can send you (temporary) dropbox links. Thank you for the hosting for so many years.

Serge and I are in touch by email about this. At some future point soon I'll get those candidates removed and repost fixed files. I'm most definitely not a math genius and wouldn't have thought about stuff like this. Apparently nobody else at PrimeGrid ever did either.

Granted, the problem only concerns people with a few selected k values.
For example, P.Benson for k=9 or L.Soule for k=243. Or the PrimeGrid's k=27. The bulk of the 4998k ABCD file is unaffected and as they say, "the average temperature of all patients in the hospital is almost normal". Some patients, though, are fairly cold (up to 57% of the candidates can be removed from future testing.) The attached perl script can be run on the full ABCD, or anyone's local PFGW or NPG files. Use it like follows: Step 1. The script is attached (below). It produces the real algebraic.txt file. 7za x so my.7z  ./dump_algebraic.pl > algebraic.txt or ./dump_algebraic.pl my.abcd > algebraic.txt Step 2. use awk '{print "3333333333333333333333  "$3}' algebraic.txt > algebraicForSrfile.txt Step 3. srfile a k algebraicForSrfile.txt my.abcd Step 4. rm algebraicForSrfile.txt , so that no one laughs their socks off when they find it one day. srfile has a "feature"  when a factor is numeric and larger than what it can handle, it accepts it and removes the candidate without questioning or complaining! If you were to use 3 instead of 3333333333333333333333, it would dutifully report that "3 does not divide <###>" and would have removed nothing.

JimB,
Since a lot of RPS work is for k<300, could you (or someone else) post a separate link that only has the sieve files for k<300 instead of k<10000? It would cut down on the download time and file opening time by quite a lot.

Jim does us a favor by posting the link; if you think a k<300 file is a good plan, how about posting it for us (at least the first time)?

New sieve files, new download location, k < 300 sieves now available
Sieve files for k*2^n1
Here are the latest sieve files for 4 < k < 10000 and n < 12M. pmin and pmax give a range of what's been completed. We kindly ask that srsieve AND psieve be credited with any primes found with these sieve files. Those are the two sieve programs used in the sieve. Should anyone wish to credit the effort (PrimeGrid) that is perfectly fine, but certainly NOT required. Please note the new file locations. Comcast is discontinuing free hosting, so these files are now hosted on PrimeGrid. The main url for these files is now http://www.primegrid.com/sieving/rsp. Because it was requested and especially since PrimeGrid has to pay for outgoing bandwidth, subsets of all the sieves for k < 300 are now available.

I forgot to edit the rsp1M6M k < 300 item counts, they're around 4.2M for rsp1M3M and 4M for rsp4M6M
