To follow up on the part of the question about using GPUs to do
arithmetic to implement DFA transitions.

It can "easily" be done.  The base ideas can be found in the Wu Mamber
string search algorithm.  You treat states like (usually one-hot) bits
in a fixed length (usually one word) bit vector.  Your transition
function then simply maps bit vectors to bit vectors.  You can do that
as a SIMD instruction, thus it is suitable for a GPU to execute.
