Dear all, I use ruby with garnet network to run parsec benchmark. The 
simulation goes smoothly without any error, except that some warnings are 
printed on the screen, as the last few lines below: "warning: add_child('cls'): 
child 'credit_links0 credit_links1' already has parent". Is this a matter 
needed to resolve? Or, I can just leave it alone, and what's the cause of these 
warnings? Thanks in advance. 
BTW, I only use stable version.
