I would have guessed the opposite. On bad hardware, Gerbicz should catch more errors than Jacobi (key word is catch; the actual number of bad iterations should be roughly equal either way), but also...

I don't think a double (53-bit mantissa) is enough precision for that number, and even a long double on x86 (which I believe gives you the 80-bit x87 extended-precision float, with a 64-bit mantissa)...

AFAIK gwnum and Prime95/mprime have the same license. I don't see a license file in the gwnum source folder, but both LLR and OpenPFGW (which both link gwnum) reference similar terms.

Yes. The gwnum license requires any 100M-digit Mersenne primes found with gwnum to be credited to GIMPS and fall under their prize rules, even if the library is linked into a program other than...

In order to distribute a GMP-ECM + gwnum binary, the whole thing would need to be licensable under the GPL. The Mersenne prime prize distribution rules in the gwnum license (even though completely...

It is highly unlikely you're ever going to get GMP to build on MSVC. Looking at the source, it's highly dependent on GNU build tools (autotools, m4, GNU Assembler), with which MSVC just isn't...

There's also the issue of licensing. gwnum's license is incompatible with the GPL (per the FSF's definition, it isn't even free, but that's irrelevant here). People have been known to link gwnum into...
