https://github.com/fluiddyn/transonic can accelerate Python/Numpy code and run on accelerators

👋 Transonic developer here. Transonic can target Pythran, Cython and Numba. Since Numba is already present in the benchmark, it's best to target the other two.

P.S.: Very cool project, btw. I came across over this on OpenBenchmarking.
