Hi,
We have a computational cluster which is consisting of 8 HP Proliant ML370G5 with 32GB ram. Each node has a Melanox single port infiniband DDR HCA card (20Gbit/s) and connected each other through a Voltaire ISR9024D-M DDR infiniband switch. Now we want to increase the bandwidth to 40GBit/s adding second infiniband cards to each node. I want to ask if this is possible, if yes how? Do I have to make a infiniband-bonding configuration or openmpi is already able to use the second card with doubling the bandwidth? Is there some one who employed such configurations?? Thanks.
