Hi,
  I have a configuration consisting of 6 nodes connected through a single IB switch. I am sending data from a single node to all the remaining 5 nodes using IB multicast. I get a bandwidth of not more than 1.5 - 2 Gbps. I was expecting it to be around 10 Gbps( i.e same as point to point b/w). Bandwidth here is defined as (total sent data from the source)/(time for getting completion acks from all the 5 nodes on receiving source data).
  1. What could be the reason?
  2. What is the expected bandwidth?
 
 regards,
-Chev
