Interesting, I'm glad Ernst added that feature. If necessary, I have access to a dual hex Ivy Bridge server with 128 GB ECC RAM for testing. Not quite as many cores as a Xeon Phi 7250, but higher...

It isn't reflecting on mersenne.ca yet, but I factored 3321928171 to 91 bits with no factor. Anyone with a Radeon VII Pro who is willing to crunch a P-1 and PRP test is good to go! :smile:

I would as well! I'm considering a dual boot into Arch Linux to use it on my 3060 Ti in the meantime.

That would be nice. I also have a 3060 Ti (MSI) but the window closes as soon as I open it. It worked fine on a GTX 1080.

Perhaps I should say fully factored...to the optimal 91 bit depth! :smile: A factor would at least avoid the arduous P-1 and PRP tests, but those will also be an interesting challenge.

I went ahead and took the liberty of reserving that exponent to 91 bits. It's a comparatively slow 100 days on my GTX 1080, but it will be good to have an exponent fully factored. I will check my...

Interestingly, according to the following link, factoring to 91 bits would require over 150K GHz-days of computation, while a LL test requires only 91K:
