I just wanted to draw the attention of NumPy devs to Mark Florisson's
It is 'minivect', a tool to use for compiling array expressions (think
(as a concept) a shared backend between Cython, Theano, numba, though
it's only used in Cython currently).
His M. Sc. thesis, "Techniques for Static and Dynamic Compilation
of Array Expressions", is up here:
As you can see he even beats Intel Fortran for some array layouts, and
in general have comparable performance with it. The benchmarks are
mostly for two-operand operations, i.e. operations where NumPy semantics
would be OK.
IMO, if anybody ever wants to revamp NumPy's computation abilities and
get that 2-3x speedup (e.g., make it multi-threaded), this is a very
good place to start.
