Command Parameters of Hyper MPI 25.1.RC1 and Later Versions

This section describes the command parameters of Hyper MPI 25.1.RC1 and later versions.

Hyper MPI 25.1.RC1 and later versions add new command parameters based on those of Hyper MPI 25.0.0 and later versions.

When using Hyper MPI command parameters to specify algorithms, you can refer to Algorithms for the meaning of specific parameter values.

Parameter

Value

Description

-x UCG_LOG_LEVEL=

  • Type: string
  • Range:
    • fatal: error that causes the program to stop immediately
    • error: error message
    • warn: alarm message
    • info: informational message
    • debug: debug message
    • trace: detailed debug message
NOTE:

Log levels are ordered as: fatal > error > warn > info > debug > trace. The lower the level, the more detailed the log output. For example, if the level is set to warn, the system will output logs at the fatal, error, and warn levels.

  • Default value: warn

(Optional) Specifies the UCG log level.

Example:

-x UCG_LOG_LEVEL=warn

NOTE:

The current release version supports log levels up to info, while the debug version supports log levels up to debug. At the debug level, logs record information such as the peer process and packet length of P2P communication. You can run the module load command to load the debug HMPI.

-x UCX_LOG_LEVEL=

  • Type: string
  • Range:
    • fatal: error that causes the program to stop immediately
    • error: error message
    • warn: alarm message
    • info: informational message
    • debug: debug message
    • trace: detailed debug message
NOTE:

Log levels are ordered as: fatal > error > warn > info > debug > trace. The lower the level, the more detailed the log output. For example, if the level is set to warn, the system will output logs at the fatal, error, and warn levels.

  • Default value: warn

(Optional) Specifies the UCX log level.

Example:

-x UCX_LOG_LEVEL=warn

NOTE:

The current release version supports log levels up to debug, while the debug version supports log levels up to trace. You can run the module load command to load the debug HMPI.
