Works perfectly! The OS is Ubuntu 20.10 (Groovy Gorilla?), and it does not surprise me that it's causing hangups for this, since it also has a recent issue that leaves it unable to compile yafu. Will...

Did what you suggested. Still no dice for srsieve2cl. It seems like most of the other cl sievers work just fine with OpenCL, though I did not make a decimal file for pixsievecl to test with.

Here's the list of candidates. I have been running it under srsieve2 (and, indeed, even with srsieve2cl with no GPU workers) with no issues, so I do think it's a GPU error on my end.

If it's not a prime distance away, it would have to be at least (n+1)^2.

Otherwise, n!+d will be divisible by the smallest prime factor of d, since the smallest prime factor of d will be smaller...

i proved the bern(8766) with ecpp twice.

it'll be a bit before i get the cofactor of bern(8286).

ughhhhhhh.

Got the wrong one. I evidently don't understand how to order candidates in Primo right, so instead I proved 798*Bern(8766)/(487*4657*6468702182951641) (23743 digits).

Currently being verified by...

For 3^n+2, I did srsieve2 -n 1 -N 1000000 -s"27*3^n+2".
For 3^n-2, I did the same but with "27*3^n-2".

Similar results occur for -s"1*3^n+2" and fails to parse -s"3^n+2", as expected.
