Resumen:
MPI for Python provides bindings of the Message Passing Interface(MPI) standard for the Python programming language and allows anyPython program to exploit multiple processors. In its first release,MPI for Python was constructed on top of the MPI-1 specificationdefining an object oriented interface that closely followed the MPI-2C++ bindings, and provided support for communications of generalPython objects. In the latest release, this package is improved toenable direct blocking/nonblocking communication of numeric arrays,and to support almost all MPI-2 features. Improvements incommunication performance have been tested in a Beowulf classcluster. Results showed a negligible overhead in comparison tocompiled C code. MPI for Python is open source and available fordownload on the web (http://mpi4py.scipy.org/)
