In exclusive execution mode, your job runs by itself on a host. It is dispatched only to a host with no other jobs running, and LSF does not send any other jobs to the host until the job completes.

To submit a job in exclusive execution mode, the queue must be configured to allow exclusive jobs.

When the job is dispatched, bhosts(1) reports the host status as closed_Excl, and lsload(1) reports the host status as lockU.

Until your job is complete, the host is not selected by LIM in response to placement requests made by lsplace(1), lsrun(1) or lsgrun(1) or any other load sharing applications.

You can force other batch jobs to run on the host by using the -mhost_name option of brun(1) to explicitly specify the locked host.

You can force LIM to run other interactive jobs on the host by using the -m

host_name option of lsrun(1) or lsgrun(1) to explicitly specify the locked host.

-aesub_application Specifies one or more application-specific esub executables that you want LSF to associate with the job.

The value of -amust correspond to the application name of an actual esub file. For example, to use bsub -a fluent, the file esub.fluent must exist in

LSF_SERVERDIR.

For example, to submit a job that invokes two application-specific esub executables named esub.license and esub.fluent, enter:

bsub -a license fluent my_job

mesub uses the method name license to invoke the esub named

LSF_SERVERDIR/esub.license, and the method name fluent to invoke the esub named LSF_SERVERDIR/esub.fluent.

The name of an application-specific esub program is passed to the master esub. The master esub program (LSF_SERVERDIR/mesub) handles job submission requirements of the application. Application-specific esub programs can specify their own job submission requirements. The value of -ais set in the LSB_SUB_ADDITIONAL option in the LSB_SUB_PARM file used by esub.

If an LSF administrator specifies one or more mandatory esub executables using the parameter LSB_ESUB_METHOD, LSF invokes the mandatory executables first, followed by the executable named esub (without .esub_application in the file name) if it exists in LSF_SERVERDIR, and then any application-specific esub executables (with .esub_application in the file name) specified by -a.esub_application.

The name of the esub program must be a valid file name. It can contain only alphanumeric characters, underscore (_) and hyphen (-).

RESTRICTION: After LSF version 5.1, the value of -a and LSB_ESUB_METHOD must correspond to an actual esub file in LSF_SERVERDIR. For example, to use bsub -a fluent, the file esub.fluent must exist in LSF_SERVERDIR.

-appapplication_profile_name

Submits the job to the specified application profile. You must specify an existing application profile. If the application profile does not exist in lsb.applications, the job is rejected.
