Hello,


first of all, I would like to thank you from the great work you have done=20
on f2py. It  is of prime interest for me and the software I currently=20
developping.
However, it has a limitative behavior that I can't solve or bypass. I hope=20
you could help me...

I use f2py to build a python-API to a huge F90 scientific software.
The tests I a am running now produce good results and I really want to=20
propose this API to my users.


--------------------- Description ---------------------

But for the needs of the end-users, I need to create multiple instances of=20
the program in the same python script (allowing sensitivity studies for=20
example).

The expected behavior could be :

>> import program as program1       # I know this can't be the final=20
solution, but I found it useful
>> import program as program2       # to write it like that (--> to=20
improve understanding)

>> program1.init( 10 )
>> program2.init( 1000 )

>> program1.run()
>> program2.run()

where program1 and program2 defines 2 different instances from the same=20
.so file.


--------------------- Investigation ---------------------

I found a thread on your mailing list (from 2003 !) which seems to deal=20
with this ( thread =3D " [f2py] multiple instances of same pyd file " ).
But I understand from it that no good solution had been identified (I may=20
be wrong). I'm wondering if, 8 years after, some new developpement (on=20
f2py or Python itself) could help doing this.


Thank you in advance if you can help me. I can give more information if=20
needed.

Regards,

C=E9dric TAVE.
