NVIDIA online tool can help you configure clusters based on FAT Tree with two levels of switch systems.
The SM is used to discover and configure all the InfiniBand fabric devices to enable traffic flow between those devices. To enable Subnet Manager: Enable Subnet Manager (disabled by default). Run: switch (config) # ib smnode my-sm enable (Optional) Set the priority for the Subnet Manager....
These counters can be found in /sys/class/infiniband/[INTERFACE]/ports/[PORT NUMBER]/counters, e.g. /sys/class/infiniband/mlx5_19/ports/1/counters. The counters of interest are:port_rcv_data - receive bytes port_xmit_data - transmit bytes port_rcv_packets - receive packets port_xmit_...
