I have some basic questions of calling a Fortran model from GAE.

I uploaded a Fortran77 code to an test Environment, and then compiled it to
a .so file using f2py commend. In the following steps, I will need to send
input values which come from user inputs by filling a Django powered form
on a GAE hosted website. What confused me is that:

   1.

   Since I have already uploaded the complied file to PiCloud, do I still
   need to publish the library (function?)? If so, how should I do it (import
   the uploaded library then publish)?
   2.

   How do I execute the function (do the calculation)? For a python
   function, I can use something like:

   "response_val = urlfetch.fetch(url=url_val, method=urlfetch.GET,
   headers=http_headers) output_val =
   json.loads(response_val.content)['result']"

However, there is no "_env=environ_name" model in fetch, so any suggestion?

Thanks in advance and any suggestion is welcomed!
