Infiniband Cluster with no Infiniband on Head Node

    Question

  • Hi,

    My customer just purchased a set of Infiniband equipment, but they forgot to include Infiniband HBA for Head node. From my understanding it seems that we will need Infiniband on Head node in order to follow the network topology with application network.

    Could we make the application use Infiniband WITHOUT the Infiniband HBA on Head node?

  • Hi Somsak,

    While it's entirely possible to configure your network outside of the 'generic' network configuration settings, it's definitely recommended that you wire up with 'supported' topologies simply because it is easier to monitor and detect failures when your head node has access to the same cluster networks as your compute nodes.
