Re: [f2py] control number of OpenMP threads at runtime

I would say it's odd that it is not recognizing the environment
variable. You can always  check that it is visible to fortran via f2py
with getenv http://darbujan.fzu.cz/cgi-bin/info2www?%28g77%29GetEnv+Intrinsic.
You could also look at setting the maximum number of threads via
omplib. If it really isn't visible for some reason, you could always

 use use(OMP_LIB)

and then omp_set_num_threads()
