180 Platform LSF Command Reference
Options related to command names and job names can contain up to 4094
characters for UNIX and Linux, or up to 255 characters for Windows.
Options for the following resource usage limits are specified in KB:
◆ Core limit (-C)
◆ Memory limit (-M)
◆ Stack limit (-S)
◆ Swap limit (-v)
Use LSF_UNIT_FOR_LIMITS in
lsf.conf to specify a larger unit for the limit
(MB, GB, TB, PB, or EB).
If fairshare is defined and you belong to multiple user groups, the job is scheduled
under the user group that allows the quickest dispatch.
The job is not checkpointable.
bsub automatically selects an appropriate queue. If you defined a default queue list
by setting LSB_DEFAULTQUEUE environment variable, the queue is selected
from your list. If LSB_DEFAULTQUEUE is not defined, the queue is selected from
the system default queue list specified by the LSF administrator with the
DEFAULT_QUEUE parameter in
lsb.params.
LSF tries to obtain resource requirement information for the job from the remote
task list that is maintained by the load sharing library. If the job is not listed in the
remote task list, the default resource requirement is to run the job on a host or hosts
that are of the same host type as the submission host.
bsub assumes only one processor is requested.
bsub does not start a login shell but runs the job file under the execution
environment from which the job was submitted.
The input file for the batch job is
/dev/null (no input).
bsub sends mail to you when the job is done. The default destination is defined by
LSB_MAILTO in
lsf.conf. The mail message includes the job report, the job
output (if any), and the error message (if any).
bsub charges the job to the default project. The default project is the project you
define by setting the environment variable LSB_DEFAULTPROJECT. If you do not
set LSB_DEFAULTPROJECT, the default project is the project specified by the LSF
administrator with DEFAULT_PROJECT parameter in
lsb.params. If
DEFAULT_PROJECT is not defined, then LSF uses
default as the default project
name.
Options
-B Sends mail to you when the job is dispatched and begins execution.
-H Holds the job in the PSUSP state when the job is submitted. The job is not
scheduled until you tell the system to resume the job (see
bresume(1)).
-I | -Ip | -Is Submits a batch interactive job. A new job cannot be submitted until the interactive
job is completed or terminated.
Sends the job’s standard output (or standard error) to the terminal. Does not send
mail to you when the job is done unless you specify the
-N option.
