hi,
why only to 70/71 bit ?
what gpu do you have ?

you need a nvidia gpu (a turing card would be nice because of the high speed)

mfaktc v0.21
the extra version for wagstaff
if you are using windows
mfaktc-win-64.Wagstaff.exe
if you are using linux
you have to compile it by yourself

Are you doing a quick PRP on all co-factors of Wagstaff numbers you found a factor for?

Me? No. Factordb? Yes.

Basically after submitting the factors to factodb, I also assign the cofactor to PRP worker. Then later on (maybe after a day or two), I go back and check for PRPs. Most of the time, if a PRP appears, it will be a false positive (side effect of base 2 numbers), but once in a while you hit paydirt.
