Threading in Python

[S.Mohideen]

Python is praised about - me too. But at one instance it fails. It fails to
behave as a true multi-threaded application. That means utilizing all the
CPUs parallely in the SMP efficiently stays as a dream for a Python
Programmer.

Discussion threads say its due to GIL - global interpreter lock. But nobody
has mentioned any alternative to that apart from suggestions like "Code it
in C" and POSH (http://poshmodule.sf.net). Is there any other way we can
make Python programs really multithreaded in real sense.

There are two ways. You can use processes, or you can use IronPython.

Or you could try Parallel Python: http://www.parallelpython.com/

"a python module which provides mechanism for parallel execution of
python code on SMP and clusters"

Also,

MYMPI: http://peloton.sdsc.edu/~tkaiser/mympi/
PyMPI: http://sourceforge.net/projects/pympi
PyPar: http://datamining.anu.edu.au/~ole/pypar/
parallel: http://cheeseshop.python.org/pypi/parallel/0.2.3

Hopefully something here is of use to you
