D4rkCrypto commented 4 months ago

Yes, PhantomFHE has been tested and verified on RTX 30 and 40 series.

Thank you very much for your reply. Why is the GPU utilization so low when I use an RTX30 series GPU?

D4rkCrypto commented 3 months ago

Probably caused by small parameters, also HE operations cannot fully occupy GPU. You can try large parameters like $n = 2^16$ and the corresponding longest modulus chain, to see if the GPU utilization is still low.

Ok, thanks for your reply, I'll try it
