Register nodes from different machines using single command

Hi,

I am using grid 2 for my execution.
I have to open browser on 60 machines. for that I need to register nodes from each machine individually.
So I need to login to each machine and run/register node from each machine.

Is there any way to register nodes from different machine using any single command?
programmatically, is it possible if yes how?

Thanks in advance,
Amol
