The following parameters need to be modified based on the actual training environment:
-`board_id`: current running environment. Set this parameter to `0x0000` for x86, and to `0x0020` for ARM.
-`server_num`: number of hosts.
-`server_count`: number of hosts.
-`server_id`: IP address of the local host.
-`device_num`, `para_plane_nic_num`, and `instance_count`: number of devices.
-`rank_id`: logical sequence number of a device, which starts from 0.
-`device_id`: physical sequence number of a device, that is, the actual sequence number of the device on the corresponding host.
-`device_ip`: IP address of the integrated NIC. You can run the `cat /etc/hccn.conf` command on the current host. The key value of `address_x` is the IP address of the NIC.
-`para_plane_nic_name`: name of the corresponding NIC.
-`rank_id`: logical sequence number of a device, which starts from 0.
