Honestly I don't fully understand and can't spend the brain power on it at the moment. If you want to take a crack at writing the code per your algorithm, then go for it. I think you have the best...

It took me a while, but I believe I see where you are going with this. Obviously as the range of n increases, so does the benefit.

ave_mulmod modifies the contents ymm4-ymm7, thus you cannot call it two times in a row and expect the result to be a*b*b mod p. You would have to call ave_set_16b or avx_set_1b after the first...

I don't know how to do bit operations with floating point values. What is the specific math you are trying to accomplish? Maybe there is a different way to get the desired result.

To be clear, the framework only has code for AVX2, not AVX512. I don't have a CPU that supports AVX512, so I cannot write or test code for it.
