I have verified all PRPs for x <= 14000. The range for 14000 < x <= 20000 has about 1.5 million terms in it. I will be starting on that soon.

The problem is a piece of algebraic factor code that is outputting the message should only be used if c = +1 or -1. I'll fix as soon as I can.

proth20 can only be used for k*2^n+1. In other words b = 2 and c = +1. Hopefully Yves will extend that to other bases and c = -1 in the near future.

My experience is that it is slower than pfgw,...

If k is so large that you cannot build Legendre tables, then srsieve2 is probably faster. The Legendre logic fully coded and tested in srsieve2.

You can use the same cache for each instance of sr2sieve that is sieving the same k, b, c, and n range, but different p range.

For goals 2 thru 5 it doesn't state the number of bases at the start of the year so it is impossible to know how much work has been done compared to what is left.

If using sr2sieve with a k in that range, make sure that you generate the Legendre tables. That should give it a nice speed boost.

You would have to test with proth20 to see how well is works. Then you would have to run some of the same tests with llr to see which one is faster.

It ran out of memory. Use -X to reduce the number of terms per chunk.

Since n is so large, you are much better off running without -x than using pfgw with the output file.
