MPI map

Documentation

This package uses mpi4py and dill to spawn processes and execute them.

Installation

You need to have an MPI back-end installed on your machine and add the right path on the $LD_LIBRARY_PATH, so that mpi4py can link to it. You should install mpi4py manually by

$ pip install mpi4py

When everything is set, you can install the mpi_map using:

$ pip install mpi_map
