HCCL_ENTRY_LOG_ENABLE

Description

Controls whether to print the runtime logs of the communication operator in real time.

  • 1: Print the runtime logs of the communication operator in real time. Specifically, a runtime log is printed each time the communication operator is called.
  • 0: Do not print the runtime logs of the communication operator.

The default value is 0.

The default path for storing HCCL runtime logs is $HOME/ascend/log/run/plog/plog-PID_*.log. For details about logs, see Log Reference.

Example

export HCCL_ENTRY_LOG_ENABLE=1

Constraints

This environment variable is used only in the single collective communication operator calling scenario.
