Charm++ parallel programming system

[Astrophysics Computer Manager <Star AT uclan.ac.uk>]

Hi Everybody,

my name is Markus Hartmann and I am a PhD student at the University of 
Central Lancashire. I am using Nbody simulations to study the formation of 
central massive objects and I would like to start using ChaNGa which needs 
the charm++ environment. 
I am trying to use ChaNGa on my MacBookPro since the new MacBooks have a 
small GPU. Is there any possibility to build charm++  so that I can use the 
CUDA compiler? There is no version available like 
multicore-darwin-x86_64-cuda or net-darwin-x86_64-cuda. 
I have not found any explanation how I could build a version by my own. Is 
there any way doing this?

Thank you very much for your help!

Regards
Markus Hartmann
