Thanks Nadya ,

I have a specific question for you. instead of using an outdate roll of 
NVIDIA and CUDA via the roll in link you mentioned, why won't I install 
the latest NVIDIA driver on nodes using skeleton. As for CUDA , I just 
need to install it on the master and  share it to the nodes thought nfs 
export.  Is there anything wrong doing it that way or do I miss something ?

Thanks for any help

Chris
