Re: [Pypar-developers] pypar: receiving without specifying source?

[Ole N. <ole...@gm...>]

By the way

The recently contributed pypar_balancer.py from Felix Richter implements a
general master-slave framework and you can see how pypar.any_source is used
in conjunction with status.source.

You can see that code at

http://pypar.svn.sourceforge.net/viewvc/pypar/source/pypar_balancer.py?view=markup

Cheers
Ole
