ssacct

Displays accounting statistics about finished LSF session scheduler jobs.

Synopsis

ssacct [-l] job_ID [task_ID | "task_ID[index]"]
ssacct [-l] "job_ID [index]" [task_ID | "task_ID[index]"]
ssacct [-l] -f log_file [job_ID [task_ID | "task_ID[index]"]]
ssacct [-l] -f log_file ["job_ID [index]" [task_ID | "task_ID[index]"]]
ssacct [-h] | [-V]

Description

By default, displays accounting statistics for all finished jobs that are submitted by the user who used the command.

Options

-l
Long format. Displays extra accounting statistics.
-f log_file
Searches the specified job log file for accounting statistics. Specify either an absolute or relative path.
By default, the ssacct command searches for accounting files in directory that is defined by the SSCHED_ACCT_DIR parameter in the lsb.params file. Use this option to parse a specific file in a different location. You can specify a log file name, or a job ID, or both a log file and a job ID. The following commands are correct:
ssacct -f log_file job_ID
ssacct -f log_file
ssacct job_ID

The specified file path can contain up to 4094 characters for UNIX, or up to 255 characters for Windows.

job_ID | "job_ID[index]"
Displays information about the specified jobs or job arrays.
task_ID | "task_ID[index]"
Displays information about the specified tasks or task arrays.
-h
Prints command usage to stderr and exits.
-V
Prints LSF session scheduler release version to stderr and exits.

Output: default format

Statistics on all tasks in the session. The following fields are displayed:

  • Total number of done tasks
  • Total CPU time in seconds used
  • Average CPU time in seconds used
  • Maximum CPU time in seconds of a task
  • Minimum CPU time in seconds of a task
  • Total wait time in seconds
  • Average wait time in seconds
  • Maximum wait time in seconds
  • Minimum wait time in seconds
  • Average turnaround time (seconds/task)
  • Maximum turnaround time (seconds/task)
  • Minimum turnaround time (seconds/task)
  • Average hog factor of a job (CPU time/turnaround time)
  • Maximum hog factor of a task (CPU time/turnaround time)
  • Minimum hog factor of a task (CPU time/turnaround time)

The total, average, minimum, and maximum statistics are on all specified tasks.

The wait time is the elapsed time from job submission to job dispatch.

The turnaround time is the elapsed time from job submission to job completion.

The hog factor is the amount of CPU time that is consumed by a job, divided by its turnaround time.

Output: long format with the -l option

In addition to the fields displayed by default in the SUMMARY output, the -l option displays the following fields:

CPU_T
CPU time in seconds used by the task.
WAIT
Wall clock time in seconds between when the task was submitted to the LSF session scheduler and when it was dispatched to an execution host.
TURNAROUND
Wall clock time in seconds between when the task was submitted to the LSF session scheduler and when it completed running.
STATUS
Status that indicates the job was either successfully completed (done) or exited (exit)
HOG_FACTOR
Average hog factor, equal to CPU time/turnaround time.
