LSF Version 7.3 - Platform LSF Configuration Reference
lsb.params
The lsb.params file defines general parameters used by the LSF system. This file contains only one section, named
Parameters. mbatchd uses lsb.params for initialization. The file is optional. If not present, the LSF-defined defaults
are assumed.
Some of the parameters that can be defined in lsb.params control timing within the system. The default settings
provide good throughput for long-running batch jobs while adding a minimum of processing overhead in the batch
daemons.
This file is installed by default in LSB_CONFDIR/cluster_name/configdir.
Changing lsb.params configuration
After making any changes to lsb.params, run badmin reconfig to reconfigure
mbatchd.
Parameters section
This section and all the keywords in this section are optional. If keywords are not present, the
default values are assumed.
Parameters set at installation
The following parameter values are set at installation for the purpose of testing a new cluster:
Begin Parameters
DEFAULT_QUEUE = normal #default job queue name
MBD_SLEEP_TIME = 20 #mbatchd scheduling interval (60 secs is default)
SBD_SLEEP_TIME = 15 #sbatchd scheduling interval (30 secs is default)
JOB_ACCEPT_INTERVAL = 1 #interval for any host to accept a job
#(default is 1 (one-fold of MBD_SLEEP_TIME))
ENABLE_EVENT_STREAM = y #enable streaming of lsbatch system events
End Parameters
With this configuration, jobs submitted to the LSF system will be started on server hosts
quickly. If this configuration is not suitable for your production use, you should either remove
the parameters to take the default values, or adjust them as needed.
For example, to avoid having jobs start when host load is high, increase
JOB_ACCEPT_INTERVAL so that the job scheduling interval is longer to give hosts more
time to adjust load indices after accepting jobs.
In production use, you should define DEFAULT_QUEUE to the normal queue,
MBD_SLEEP_TIME to 60 seconds (the default), and SBD_SLEEP_TIME to 30 seconds (the
default).
ABS_RUNLIMIT
Syntax
ABS_RUNLIMIT=y | Y
Description
If set, absolute (wall-clock) run time is used instead of normalized run time for all jobs
submitted with the following values:
•
Run time limit specified by the -W option of bsub
