    How to configure two HCAs in a compute node?



      I am trying to install 2 Connect-X3 HCAs in a compute node. Each HCA was inserted to corresponding PCIe slot of a CPU and I have installed Ubuntu 16.04 LTS.

      Ubuntu detects the HCAs and I can see them with sudo lspci | grep "Mellanox".

      I am doing this because I would like to install 4 Xeon Phi co-processor to the node and each Phi will be linked to respective HCA of the same CPU. Each Phi needs an IP in the cluster.

      For example,

      HCA1 ib0, Phi_0, Phi_1

      HCA2 ib0, Phi_2, Phi_3

      I will install MLNX_OFED_LINUX-3.4- on the node, so what is the best practice to achieve such configuration?

      My experience with phi installation on Ubuntu 16.04 is successful.

      How to setup 4 Xeon Phi 7120P in a single node via Infiniband?

      Thank you,
