You are correct, the value of the exponent does in fact matter. But for n<50K and maybe n<100K for base 3, I would think that PFGW is the fastest alternative, simply because the input/output read/write of the .ini file takes too long as the ini file grows due to the growing number of primed k's. But as always, just like with multithreading and everything else that is somewhat system dependant, test locally and figure out what actually is most optimal program to use. And yes, one of the reason PFGW is used for starting up bases is among other features, the reason that PFGW writes once a minute (Thanks Mark for clearing that) in stead of several times a second, when doing very small tests

I was doing small base 3 tests (n=25K50K). I did not know there was much time difference between the two. Anyway I still prefer LLR because I am stopping the programs frequently to do other stuff and I don't want to have to worry about whether the program will "lose" the knowledge that previous primes were found.

I use srsieve2 to reformat the output as ascending k then ascending n. It makes it a lot easier to work with the input file and it allows one to compute a better estimate as to when processing of the file will be completed.

Here is the next batch of R66 primes. All k thru 44451283 are tested to n=25000.

Primes in that group already found prime for n=10K11K: 15 Unique k's found prime for k=17.578M44.4515M n=11K25K: 9175 R66 previously remaining at n=25K: 95114 Primes found for k=17.578M44.4515M n=11K25K: 9175 R66 k's now remaining: 85939 Attached are the 15 k's that were found prime for n=11K25K that already had a prime for n=10K11K. I'm hoping that will help you save some time in your remaining searches. Last fiddled with by gd_barnes on 20200508 at 00:52

See the attachment to the previous post. They were in a fairly narrow krange of k=36.5M38.6M so you probably missed removing them in one file or something like that.

You are correct. They were all in primes_14.log. None were in any of the other 9 files I submitted.

S81 k=2036, the test limit should be 1.5M instead of 1M
