If you have actually found a new EVEN perfect number, you've also found a new Mersenne prime, and will become famous (and possibly win money).

Has any effort been made to update the credit formula? What would (or could) it look like today? And would it be best to prioritize work that either tests or factors exponents at the wavefront?

Okay. So your setup is:

1. You have a 130-digit semiprime, and

If that's the case, you can use...

All this talk of fuzz testing weird/nonstandard inputs to GMP-ECM (including kriesel's essays) should be moved to another thread. This thread is about factoring M1277.

One question: mprime does a bunch of internal error checking (Jacobi / gw_square_carefully / etc) to be resilient to hardware errors. Is that done here?

This is pretty awesome. An open source ECPP implementation that is fast, pure C, and highly scalable with MPI.

Can't wait to see how this gets extended and improved. Hats off to Andreas!
