Benchmark expression broadcast
==============================

.. literalinclude:: bench.py

This example uses the ``boost`` decorator, so the Python file needs to be
transpiled by Transonic and the accelerator files need to be compiled. You can
for example run from the directory ``doc/examples/bench_proj_perp``::

    make clean
    make
    python bench.py

The last command gives something like::

    Transonic 0.4.1
    Pythran 0.9.3post1
    Numba 0.46.0
    Cython 0.29.13

    broadcast                        : 1.000 * norm
    norm = 1.55e-04 s
    broadcast_numba                  : 0.462 * norm
    broadcast_loops_numba            : 0.433 * norm
    broadcast_pythran                : 0.270 * norm
    broadcast_loops_pythran          : 0.408 * norm

For the solution with loops, the 2 backends are equally good.

For Pythran, it is even faster with the high level implementation!
