With Cython’s prange, we can choose different scheduling approaches. from re import setupįrom distutils.extension import Extension We tell it to inform the C compiler to use -fopenmp as an argument during compilation - to enable OpenMP and to link with the OpenMP libraries. To compile cython_np.pyx we have to modify the setup.py script as shown below. When working in a prange stanza, execution is performed in parallel because we disable the global interpreter lock (GIL) by using the with nogil: to specify the block where the GIL is disabled. CythonĬython has OpenMP support: With Cython, OpenMP can be added by using the prange (parallel range) operator and adding the -fopenmp compiler directive to setup.py. You could easily write C extensions that use multiple threads in Cython, example. You need either multiprocessing ( example) or use C extensions that release GIL during computations e.g., some of numpy functions, example. PS.Due to GIL there is no point to use threads for CPU intensive tasks in CPython. I am available and willing to contribute further detail into the matter.

PIP INSTALL OPENMP UPGRADE

# intelpython is disabled because not signed (apt upgrade gives error message) Should I maybe install something else before the above commands ?Ĭontent of /etc/apt//: $ cat /etc/apt//intelproducts.list I didn't need to pip uninstall numpy because mkl environment is brand new and no numpy is in there.

same with intel-scipy and numpy-mkl (same error message).

pip install intel-numpy (error message follows).

then I tried the following pip install commands.

There are many (see list below) and I am in doubt of what to install.

activated the mkl virtual environment ( pyenv activate mkl), and checked the available packages with pip search mkl and pip search intel.

PIP INSTALL OPENMP UPDATE

I ran apt update and apt upgrade (succesfully).

PIP INSTALL OPENMP CODE

I have registered the intel repositories in `apt`, see the file /etc/apt/intelproducts.list in code section below.

PIP INSTALL OPENMP HOW TO

I NEED CLEAR INSTRUCTIONS HOW TO PROCEED (which packages to install) (Python version of that environment is 3.7.6) I want to install intel-numpy or numpy-mkl (clarification needed!) in a pyenv/virtualenv environment with the `pip install` command. I am trying to make my python3/numpy scripts go faster, by using MKL which supposedly will use many or all processor cores/threads. I am on an Asus notebbok with an i7 8550 processor, OS is Ubuntu 18.04.
