Queries or removes information about the energy policy tag from the mbatchd daemon, which is saved in the energy-aware scheduling database. Used with energy policy, or energy aware scheduling feature.


bentags [-o cpu_frequency | -o time | -o energy] [-u user | -u all] [energy_tag...]
bentags -r [-u user | -u all] [energy_tag...]
bentags [-h | -V]


The energy policy tag is the unique identifier of a job’s energy data, used to identify the predicted energy usage, predicted run time of the job, and the job performance degradation. The energy policy tag name is specified by using esub.eas. When you submit a job, make sure that the energy policy tag name is unique for each of your jobs.

The bentags command displays all the energy tag names that are generated by the user. When you remove an energy tag, specify the tag name or user name. If you specify the user name, all tags that belong to that user are removed. Only an LSF administrator and root can remove another user’s energy policy tags.


Provides extended help information.
Displays the name of the command, release number, service level, service level date, and lowest level of the operating system to run this release.
-o cpu_frequency | time | energy
Sort the energy tag’s data by cpu_frequency / time / energy, in descending order. Default is to sort by CPU frequency. cpu_frequency matches to CPU_FREQ, time matches to EST_RUNTIME, and energy matches to EST_USAGE.
Remove energy policy tag. This option must be followed by the –u option or an energy tag name.
-u user_name... | -u all
Displays only the energy policy tags that are submitted by the specified user. The keyword all specifies all users. To specify a Windows user account, include the domain name in uppercase letters and use a single backslash (DOMAIN_NAME\user_name) in a Windows command line or a double backslash (DOMAIN_NAME\\user_name) in a UNIX command line.
Display the data of a specific tag name.

Output: Energy tag data

Energy Tag Name
The energy tag name.
Job ID
The identifier of the job that generated the data.
The user who generated the data.
Default Frequency
The CPU frequency that is used when the energy tag is generated.
Node's Energy Use
The direct current (DC) energy consumption per node of the job at the default frequency.
The execution time of the job at the default frequency.
The CPU frequency.
The job’s estimated DC energy consumption per host, at this frequency.
The percentage of variation in DC energy that is consumed at this frequency. A negative value indicates the percentage of energy savings and a positive value indicates percentage of additional energy consumed.
The estimated run time of the job at this frequency.
The percentage of performance variation at this frequency. A negative value indicates the performance improvement and a positive value indicates the performance degradation.
The power, measured in watts (W).

Example: Remove UserA.long_running_job energy policy tag from database

Use bentags -r UserA.long_running_job to remove UserA’s long_running_job energy policy tag from the database.
bentags -r UserA.long_running_job
The energy policy tag <UserA.long_running_job> is removed.

Example: Remove all energy policy tags for UserA

Use bentags -r -u UserA to remove all of UserA’s energy policy tags from the database.
bentags -r  -u UserA
The energy policy tag <UserA.long_running_job> is removed.
The energy policy tag <UserA.short_running_job> is removed.
The energy policy tag <UserA.medium_running_job> is removed.
