I was wondering why it's not possible for 321 to be sieved the same way PPS is via a GPU? Just curious. Thanks in advance.

It could certainly be done. You would just need to change the parameters passed to the sieve program.

But the GPU is not very efficient when sieving a single K, so it would run very slowly. Only some tasks work well on a GPU. Sieving a single K, or a small number of individual Ks like you would do with the conjectures (ESP/PSP/SoB/TRP/SR5) just isn't a good fit for a GPU.
