I think there may be a worthwhile modification of my suggestion merging Zhangrc's suggestion and mine. After posting a [BADLY FLAWED] suggestion above is perhaps fixable?

Ahh, I see my error. I was comparing 3^Mp-1 to 2^n-1 instead of 3^(2^n-1).

About the trial factoring to GPU72 depth, I don't have a way to TF the exponent to that depth. I tried setting it up on my computers and failed miserably. Is there a thread to make TF requests for...

Possible extension to P-1 Stage 2

I know lots of these ideas come along, and I am getting more comfortable with the math involved with Stage 2 as I write this, so please forgive me if I missed something.

From what I understand,...

I was making a suggestion for stage 2, where just one additional prime at a time is being tested (as far as I understand it). In fact a value of B1=10^6 has approximately 72000 prime factors, so 18.4...

To piggyback on this idea, could we also go the other way? Could we use a saved value of B1 and also a small power of 3 times one of the last few iterations of the PRP test do a quick 2nd B1 test?...

How many tests are saved with those bounds? I set the number of tests saved to 1, 2, and 1.1 just to experiment and I can't reproduce those bounds.

Should I re-do PM1?

I am working on a 100M digit exponent and I noticed that the P-1 test has been done with bounds B1=100000, B2=1000000. Even on a low-ram PC, I blow these bounds out of the water. In terms of saving a...

I have a laptop with a really good proc and 32 gigs of ram I can copy/paste the exponent into. Is there a benefit to using a video card or anything like that to do P-1 on the exponent?

New warning, didn't appear way back in the day

I just switched p95 v30.3 to run two threads instead of one to see if it would get a better throughput. Is it normal to get the following warning ONLY when running two threads and not one?
