We are buying a new cluster with 8-code nodes and infiniband, and have a 
choice between 10 Gbit/s and 20 Gbit/s transfer rates between nodes. I do 
not immediately see the need for 20GBit/s between nodes, but thought it 
might be worthwhile to ask for the experts' opinions regarding this? 

Is there any foreseeable advantage of having 20 Gbit/s connections as 
opposed to 10 Gbit/s? 

Thank you for the advice,

-Himanshu
