I'm assuming it is still GNFS but GPU backed. For reference, check this out: > cuda-sieve is an experimental, standalone CUDA implementation of the lattice-sieving relation-collection pipeline used by the Number Field Sieve. It builds factor bases, sieves both sides of a special-q lattice, performs trial division and GPU cofactorisation, and emits relations for msieve. https://github.com/kyleaskine/cuda-sieve https://github.com/kyleaskine/cuda-sieve
