CM_CHIEF_IP

Description

In the TensorFlow distributed training or inference scenario, you can choose not to use the ranktable file. Instead, you can use the environment variables CM_CHIEF_IP, CM_CHIEF_PORT, CM_CHIEF_DEVICE, CM_WORKER_SIZE, and CM_WORKER_IP to automatically generate resource information and initialize the collective communication component.

The CM_CHIEF_IP environment variable is used to configure the listening host IP address of the master node.

The value is a character string in IPv4 or IPv6 format.

Example

export CM_CHIEF_IP=192.168.1.1

Restrictions

This environment variable cannot be used together with RANK_TABLE_FILE, RANK_ID, or RANK_SIZE.
