Re: threading support in python

Hi, You might want to split your calculation onto different worker-processes. Then you can use POSH [1] to share data and objects. You might even want to go a step further and share the data via Sockets/XML-RPC or something like that. That makes it easy to throw aditional boxes at a specific calc
