S561 is tested to n=6175 there is 7027 sequences remaining.
I'm amazed how prime this conjecture is. Now srsieve2 is set to sieve, untill it takes about 18 seconds per factor. This should be around p=240G

It did not work, it seems that it starts from p=0 and then researches all those factors I had already found and tested below ~p=31.5G  I must add, that I used the p flag and yet it took up more and more memory and kept writing p=0 nanM (or something similar). My GPU is 7 years old, so it might not be suited

It looks like this and continues indeffinently, with use of more and more RAM:

Can you post your abcd file (7z format) or send via email? I will take a look.

Hmm. When i was testing srsieve2cl on my GPU i had to raise "maxfactordensity". Try raising it to 25000 with M 25000 and run it again. It *should* give you an warning if the density is to low (which is normaly set to 10).

For now avoid using W with srsieve2cl. By default it will use W0 and G1. It will use the CPU for testing until p > 1e6 then switch to the GPU.
