How to install multiprocessing
- Download and install ActivePython
- Open Command Prompt
pypm install multiprocessing
multiprocessing is a back port of the Python 2.6/3.0 multiprocessing package. The multiprocessing package itself is a renamed and updated version of R Oudkerk's pyprocessing package. This standalone variant is intended to be compatible with Python 2.4 and 2.5, and will draw it's fixes/improvements from python-trunk.
This package would not be possible if not for the contributions of not only the current maintainers but all of the contributors to the original pyprocessing package listed here
The multiprocessing package monkey patches several aspects of the threading module to make it forward compatible with Python 2.6. The patches are non-intrusive and don't change existing functions. See multiprocessing.patch for detailed informations.
Please refer to http://www.python.org/doc/2.6/library/multiprocessing.html for more information about the multiprocessing package.
