I think encouraging the upgrade is a good idea regardless.

I'm ambivalent about DCes being done as LL or PRP+CERT. Cost is about the same. LL-DC provides feedback on the original computer which...

Please PM or email to me the prime.txt and local.txt files.

Is hours-per-day you expect to run mprime set to something other than 24?
If so, set it to 24 and try again.

Running 4 workers is fine. In Test/Workers, have each worker use just one CPU core.

Note that running 4 PRP tests at a time will quadruple the amount of temporary disk space the program uses. At...

There is no way to convert the assignment on the server, but it will accept a PRP result from your computer.

P-1 bounds are a balancing act. As first stage processing of B1 becomes more efficient, the optimal B2/B1 ratio decreases. If B1 processing were to drop to zero cost, no stage 2 would make sense. ...

The Wh4 code is not really used anymore. Over time it loosely relates to gwnum FFT library version number. The middle letter gets bumped when there are major changes to the FFT code.

Blame it on PRP proofs. Before, exponents were in one of a several tables. Now, while waiting for a proof to be uploaded the exponent is in none of those tables. It will get patched up someday.

Right now we are getting about 19 bits per double (19/64 = 29.7% efficiency)

I did enough work to prove to myself it was feasible and, at the time,...
