S428 k=8, up to n=1M sieved to 3e13 (or 30T). This means deep sieved. Finding a factor actually went much slower that the cllr went, at that depth. So, either my cllr is too fast, or my sr1sieve is too slow (read: I am doing something wrong, with the speeds I get I would stop somewhere at 15T-18T or so), but I still followed what people suggested, to go to 30T.

Additional in the zip, there is a double check of S428, as high as it could go during the sieving process in a parallel core, which I used for speed comparison (about n=180k), which may be needed by Gary or not.

Manual edit can be done on the sieve file to split the range, and eventually sieve the higher range higher (pun intended).

There is also a "sandbox" folder where I tried - without success - to find a reasonable prime for k=2 and k=4. Strange or not, there is no other prime to (about) n=110k (see the files), beside of the trivial known primes.

The file can be deleted by a mod, to save my quota of uploading space, when it was taken by the interesting parts (for Boinc and by Gary for DCs).

I may have goofed the sieve-depth estimate! If the file is 500k to 1M, the time per factor should be about twice as long as the time to LLR a 500k candidate. This accounts for the longer testing times as you proceed toward 1M. If the file goes lower than 500k, the usual heuristic is to find LLR time for a candidate about 2/3rds of the way through the file, and sieve until factor time matches that LLR time; so, if you have 100k to 1M, you'd measure LLR for a candidate around 700k. These estimates assume the same machine will sieve and LLR.

Sorry if my previous guesses caused you to oversieve- just think of the time you saved the BOINCers!

It wasn't any sort of complaint. This is how we learn. I was only wondering if my method is the right one or not, or if I was using the right tools. I also sieved 200k-300k strictly, and I could get about ~55M pps (primes per second) while all the range to 1M gave me about ~43M pps. So I let it run with all range. Also, these times were with P95 stopped. When P95 runs, they get to about a bit more than half. This can be seen in the result files where occasional stop/run of other programs (including p95) makes the testing time per each n to jump to double or to half. Somewhere in the middle of the DC result file there is a test for a n=200k for speed comparison, I let it there and added a comment, hope this does not make the automatic parser dizzy.

I received another batch of sieve files from Ian. This time specifically for n=25K-100K. There are now links to all of them on the pages. They are as follows:

Code:
R225
R442
R445
R451
R943
S225
S442
S445
S451
S943

Another batch received from Ian again. This time for n=50K-100K. There are links to all of them on the pages. They are as follows:

Code:
R52
R147
R168
R192
R262
R270
R292
R393
R477
S95
S105
S108
S143
S147
S247
S955 (50K-75K)
S1027
Because it has so mank k's remaining, S955 is only sieved for n=50K-75K.

Quite a few of these bases have a lot fewer k's remaining than a lot of bases searched to n=25K and so would be considered higher priority. Only two of the bases are > 500 so most of them should be fairly easy, especially for BOINC, to search for n=50K-100K.

wow, a big thx to Iain, thats a lot for the future. I will add soon some of these 50-100k ranges :)
