I think the next calculation maybe need CUDA GPU to calculate with massive number calculate (maybe style like brute force calculate)
maybe you can find cheap coder CUDA on Fiverr
another way fast calculate without GPU is to try using python with multiprocess (multi-core CPU) to replace
of course, it is still slower than using CUDA GPU to calculate
AMD Ryzen Threadripper 3990X 64-Core, 128-Thread cost over $7000 still expensive same cust of hi-end 2GPU)
programmer CUDA will be coded if they interesting in that idea
