Python Parallel Programming Cookbook
By :
The Python programming language provides a number of MPI modules to write parallel programs. The most interesting of these is the mpi4py library. It is constructed on top of the MPI-1/2 specifications and provides an object-oriented interface, which closely follows MPI-2 C++ bindings. A C MPI user could use this module without learning a new interface. Therefore, it is widely used as an almost full package of an MPI library in Python.
The main applications of the module, which will be described in this chapter, are:
Point-to-point communication
Collective communication
Topologies
The installation procedure of mpi4py using a Windows machine is, as follows (for other OS, refer to http://mpi4py.scipy.org/docs/usrman/install.html#):
