I use python for my algorithm which uses only one core and I need more processing speed.

I have i7 6700K CPU with 8 cores. How to convert them to one core to have a total performance of 8 cores?

Multiprocessing and multithreading python modules don't fit in my case.

Effectively, what you are asking, is how to take advantage of a multicore architecture without parallelizing code yourself. There are no ideal solutions for that, most likely, you will have to parallelize the code yourself manually; otherwise, you are bound to use a single core.

Nevertheless, there are a couple of things one can take advantage of:

  1. If your algorithm happens to use other modules that already do the parallelization on their own, you might have to simply ensure the parallelization is used.
  2. Look into some now-available semi-automatic parallelization modules, like Pydron.
  3. Look into some area-specific automatic parallelization modules, similar to AutoParallel.
  4. Consider automatic parallelization with @jit using Numba. Numba is pretty powerful but may require you to rewrite a lot of your existing code.

In conclusion, there is stuff to explore, but there is no such thing as turning multiple cores into a more efficient single core.
