<div>Hi,</div>
<div> 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). </div>
<div> 1. What could be the reason?</div>
<div> 2. What is the expected bandwidth?<br> </div>
<div> regards,</div>
