I have a question regarding f2py: Can it map NumPy arrays to Fortran 95 'dope vectors'? I can find many examples on interfacing Fortran 77 with NumPy, but not Fortran 95. This is of course very different as Fortran 77 are always contiguous, whereas Fortran 95 arrays are not. Thus a Fortran 95 compiler will pass a pointer to a struct referred to as a 'dope vector', which by the way is very similar to a NumPy ndarray. But the ABI for a 'dope vector' is implementation (compiler) dependent. So what does f2py do? Can it use Charm? Sturla Molden
