fut-ff is a Futhark program designed to be compiled to OpenCL code and run on a GPU. Its
goal is to implement generic finite field operations, but it has only been indirectly (through use in
neptune-triton) stress-tested with the arithmetic field of the
BLS12-381 curve. Further work is needed to refine, optimize, and
provide exhaustive coverage for a general-purpose implementation. What has been implemented suffices for correct
Poseidon hashing as provided by neptune and verified by GPU tests there.
Initial design and algorithm details were partially based on (the source which has now become) ff-cl-gen.
fut-ff was written by porcuquine.
