You should be able to manually convert the Prime95 save file into a GMPECM save state. IIRC, there should be a HowTo on this somewhere on this forum (by kriesel?). I have done this for the old save file format at least once successfully. GMPECM with OpenMP will be much more performant for stage 2 and multiple cores.

No. You found out what George already told you: Prime95 is not the right software for small Mersennes and large bounds.

I have not tested with known factors, but I guess we could work something out from here.

Recently kruoli previously posted about a manual method for prime95 P1 > gmpecm. What I was looking for was CUDAPm1 > anything reliable. If someone knows of a way, please contact me by PM or post it here. edit: There's a maintained list of some P1 self test candidates with known factors scattered across a wide range of exponents and therefore many fft lengths here "(Not everyone does.)" was about certain folks who start a new thread asking a question that's easily answered by looking in the program documentation, or reference info, or with a quick forum or web search. And who continue to do so after repeatedly drawing flak from both ordinary users and moderators. And often it's the same few who don't bother to do enough independent thinking or testing. Not related to the previous posters in this thread. Last fiddled with by kriesel on 20211119 at 21:15
