python3-mpi4py - 3.1.6-1 main

MPI for Python (mpi4py) provides bindings of the Message Passing
Interface (MPI) standard for the Python programming language,
allowing any Python program to exploit multiple processors.
.
mpi4py is constructed on top of the MPI-1/MPI-2 specification
and provides an object oriented interface which closely follows MPI-2
C++ bindings. It supports point-to-point (sends, receives) and
collective (broadcasts, scatters, gathers) communications of any
picklable Python object as well as optimized communications of Python
object exposing the single-segment buffer interface (NumPy arrays,
builtin bytes/string/array objects).
