Default Should MM31 be added to the search?

I strongly need your opinion.

Aketilander just pointed out that E.W.Mayer worked on MM31 up to 1015, and showed his will to take it to 86 bits.

1 - I can't test mmff because of lacking of a new-generation GPU: is the program ready to work on MM31?
2 - Do you think that the new double Mersenne number shoud be added to the reservations list?

Thanks in advance for your opinion.

Luigi

Thank you Luigi. I am using mfaktc for the TF as I do in Operation Billion Digits so there is no need to modify mmff. If more persons would like to work on MM31 I would be more then willing to share the work. If I can reserve it up to ^86 I would be more then happy though since the work is already in progress.

MM31 doesn't work at the moment in mmff, it says:
"WARNING: exponents < 1000000 are not supported!"

which is wrong since MM31 = M2147483647 > 1000000.

IIRC, mfaktc has some limitations to go high on k (was it 93 bits?),, nd is bit-level driven instead of k-driven...

Has Oliver (TheJudger) worked on a version that permits to choose k ranges?

I think 95 bits: mfaktc Limits

... but I never think we'll reach that high!?

That was just an evaluation. I'm more concerned about giving k ranges to mfaktc.

mfaktc's limit is 2^92 factors.

Oliver is not working on k ranges. It would probably be easier to yank the relevant kernels out of mfaktc and add them to mmff.

I see...

Well, I will wait until mmff is mature for production use, then I will kindly ask if you (or someone around here) is going to take the challenge... or explain to me where and how to work I still have little knowledge of CUDA programming, but I'm eager to learn.

Meanwhile, the website will be ready to delivery whatever double Mersenne with p prime.
