lsb.queues Structure
Each queue definition begins with the line Begin Queue and ends with the line
End Queue. The queue name must be specified; all other parameters are optional.
ADMINISTRATORS
Syntax
ADMINISTRATORS=
user_name | user_group ...
Description
List of queue administrators.
Queue administrators can perform operations on any user’s job in the queue, as well as
on the queue itself.
Default
Undefined (you must be a cluster administrator to operate on this queue)
BACKFILL
Syntax
BACKFILL=Y
| N
Description
If Y, enables backfill scheduling for the queue.
A possible conflict exists if BACKFILL and PREEMPTION are specified together. A
backfill queue cannot be preemptable. Therefore, if BACKFILL is enabled, do not also
specify PREEMPTION=PREEMPTABLE.
BACKFILL is required for interruptible backfill queues
(INTERRUPTIBLE_BACKFILL=seconds).
Default Undefined (no backfilling)
CHKPNT
Syntax
CHKPNT=
chkpnt_dir [chkpnt_period]
Description
Enables automatic checkpointing for the queue.
The checkpoint directory is the directory where the checkpoint files are created. Specify
an absolute path or a path relative to CWD, do not use environment variables.
Specify the optional checkpoint period in minutes.
Job-level checkpoint parameters override queue-level checkpoint parameters.
Only running members of a chunk job can be checkpointed.
To make a MultiCluster job checkpointable, both submission and execution queues must
enable checkpointing, and the execution queue setting determines the checkpoint
directory. Checkpointing is not supported if a job runs on a leased host.
Default
Undefined
CHUNK_JOB_SIZE
Syntax
CHUNK_JOB_SIZE=
integer
Description
Chunk jobs only. Enables job chunking and specifies the maximum number of jobs
allowed to be dispatched together in a chunk. Specify a positive integer greater than 1.
The ideal candidates for job chunking are jobs that have the same host and resource
requirements and typically take 1 to 2 minutes to run.
