Regarding your suggestion, I have made a draft article here:
http://www.scipy.org/Dynetrekk/f2py_OpenMP_draft
The text is rather minimal so far, but the example does work, and a speedup close to 4 is demonstrated on a 4-core intel machine. I would be interested to hear any comments whether this is understandable reading, and test results on other OS-es and compilers. Also, I guess someone familiar with other compilers might be able to port the example. I would be interested in the Portland Group compiler example myself, as I have not managed to get this one working.

Hope this is useful for someone,
Paul.
