Sets the hard limit and/or soft limit for the elapsed time for which a job can run. In computing the elapsed time for a job, LoadLeveler considers the start time to be the time the job is dispatched.
If you are running the LoadLeveler Backfill scheduler, either users must set a wall clock limit in their job command file or the administrator must define a wall clock limit value for the class to which a job is assigned. In most cases, this wall clock limit value should not be unlimited. For more information, see Choosing a Scheduler.
The syntax is:
wall_clock_limit = hardlimit,softlimit
An example is:
wall_clock_limit = 5:00,4:30
See Limit Keywords for more information on the values and units you can use with this keyword.
