Sorry for the delay @martinmestre! Can you say a bit more about how you are using the `MultiPool`, and what kind of machine you are running on? When I test...

Agreed! I would definitely welcome that, but just ask for some examples / documentation. Thanks!

👋 Hey @avivajpeyi It looks like you are running on a mac or linux machine - if on Mac, can you try: ``` sysctl -n hw.ncpu ``` Or if on...

OK a few more tests. First off, let's see which version of MPI your shell finds first: ``` $ which -a mpiexec ``` Just because `mpiexec` is running with a...

AFAIK this is restricted to 1 node (like multiprocessing) - I don't think joblib has a standard MPI backend right now.

I tried following the tests in `mpi4py`, but still couldn't get it working for this project. See, e.g., https://github.com/mpi4py/mpi4py/blob/master/conf/coverage.sh

That would be nice to have! Do you want to try implementing? It may take me some time to get to this.

Hi @IncubatorShokuhou - Unfortunately it looks like it may be an issue with your MPI or mpi4py installation. I tried running this script on my laptop (Mac, openmpi installed via...
