lsb.queues Structure
Platform LSF Reference
424
Description
Time periods during which jobs in the queue are allowed to run.
When the window closes, LSF suspends jobs running in the queue and stops dispatching
jobs from the queue. When the window reopens, LSF resumes the suspended jobs and
begins dispatching additional jobs.
Default
Undefined (queue is always active)
RUNLIMIT
Syntax
RUNLIMIT=
[default_limit] maximum_limit
where default_limit and maximum_limit are:
[hour
:]minute[/host_name | /host_model]
Description
The maximum run limit and optionally the default run limit. The name of a host or host
model specifies the run time normalization host to use.
By default, jobs that are in the RUN state for longer than the specified maximum run
limit are killed by LSF. You can optionally provide your own termination job action to
override this default.
Jobs submitted with a job-level run limit (
bsub -W) that is less than the maximum run
limit are killed when their job-level run limit is reached. Jobs submitted with a run limit
greater than the maximum run limit are rejected by the queue.
If a default run limit is specified, jobs submitted to the queue without a job-level run
limit are killed when the default run limit is reached. The default run limit is used with
backfill scheduling of parallel jobs.
If you specify only one limit, it is the maximum, or hard, run limit. If you specify two
limits, the first one is the default, or soft, run limit, and the second one is the maximum
run limit. The number of minutes may be greater than 59. Therefore, three and a half
hours can be specified either as 3:30, or 210.
The run limit is in the form of [hour
:]minute. The minutes can be specified as a number
greater than 59. For example, three and a half hours can either be specified as 3:30, or
210.
The run limit you specify is the normalized run time. This is done so that the job does
approximately the same amount of processing, even if it is sent to host with a faster or
slower CPU. Whenever a normalized run time is given, the actual time on the execution
host is the specified time multiplied by the CPU factor of the normalization host then
divided by the CPU factor of the execution host.
If ABS_RUNLIMIT=Y is defined in
lsb.params, the run time limit is not normalized
by the host CPU factor. Absolute wall-clock run time is used for all jobs submitted to a
queue with a run limit configured.
Optionally, you can supply a host name or a host model name defined in LSF. You must
insert ‘
/’ between the run limit and the host name or model name. (See lsinfo(1) to
get host model information.)
