HCCL_ENTRY_LOG_ENABLE

Description

• 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.

The default value is 0.

export HCCL_ENTRY_LOG_ENABLE=1

Restrictions

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