Charm++ parallel programming system

["Kale, Laxmikant V" <kale AT cs.uiuc.edu>]

Do you want to run it as an application on a single multicore computer (e.g. 
desktop?) or a cluster?
If it is a cluster, you are already talking about separate processes anyway. 

For multicore, it is possible to dig deeper into the system (i.e. in 
COnverseInit) to the point where the Charm++ main function is called, and try 
to interface Qt code there.. But I'd think its going to be a bit messy. You 
can of course do a separate pthread within the same process.
