Hello,
I'm also unable to use openmp.
I did the following:
File setup.py:
==========================================
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
ext_module = Extension(
"test",
["test.pyx"],
extra_compile_args=['-fopenmp'],
extra_link_args=['-fopenmp'],
)
setup(
name = 'test',
cmdclass = {'build_ext': build_ext},
ext_modules = [ext_module],
)
==========================================
File test.pyx
==========================================
from cython.parallel cimport parallel, prange
def toto(long N):
cdef long i,j,k
cdef long ret = 0
with nogil, parallel():
for i in prange(N, schedule='dynamic'):
ret = i*i
return ret
def titi(long N):
cdef long i,j,k
cdef long ret = 0
for i in xrange(N):
ret = i*i
return ret
==========================================
When loading file setup.py in sage (5.2.beta0), I have the following error
message
==========================================
sage: load ~/tmp/setup2.py
---------------------------------------------------------------------------

Type %exit or %quit to exit IPython (%Exit or %Quit do so unconditionally).

==========================================
Any help to get it working is more than welcome !
Best,
David.
