==== lsb.resources ====
<pre>
# User Define Limits
Begin Limit
NAME = job_exec_resource_limits
USERS = user1 ~user2
SLOTS = 1
MEM = 100
End Limit
</pre>

* Run: '''badmin reconfig''' after making changes to lsb.resources

'''Note:'''
* SLOTS = 1 - User can submit more than 1 job but only 1 job will be active at a time. The rest will be in PEND state
* MEM = 100 - Restrict memory usage to 100MB
* USERS = user1 ~user2 - This limit apply to user1 but not user2
* If Both JOBS and SLOTS limits are define, the most restrictive limits is used
* Use '''bresources''' to check what resource limuits currently defined

Example:
'''bresources''' shows:
<pre>
Begin Limit
NAME = job_exec_resource_limits
USERS = user1 ~user2
SLOTS = 1
MEM = 100
End Limit
</pre>

Submit job as user1:
* bsub -R "rusage[mem=200]" ./myjob

Job will be submmited and it will be in pending state.
* Use '''bjobs''' to confirm
* Use '''bjobs -p''' to see the reason of the pending state

<pre>
bjobs -p
JOBID USER STAT QUEUE FROM_HOST EXEC_HOST JOB_NAME SUBMIT_TIME
490 user1 PEND normal vhpchead *nit2.bash Jun 4 12:34
Resource (mem) limit defined on user or user group has been reached;
491 user1 PEND normal vhpchead *nit2.bash Jun 4 12:35
Resource (mem) limit defined on user or user group has been reached;
492 user1 PEND normal vhpchead *nit2.bash Jun 4 12:36
Resource (mem) limit defined on user or user group has been reached;
</pre>

==== lsb.queues ====

'''Exclude user9 from a queue name normal'''

<pre>
Begin Queue
QUEUE_NAME = normal
.
.
USERS = ~user9
.
End Queue
</pre>

Submit job as user9:
* bsub ./myjob
<pre>
normal: User cannot use the queue. Job not submitted.
</pre>

'''Exclude Unix''' '''''users''''' '''group from a queue name normal'''
<pre>
Begin Queue
QUEUE_NAME = normal
.
.
USERS = lecturer1 ~users
.
End Queue
</pre>

* bqueues -l normal
<pre>
QUEUE: normal
.
.
USERS: lecturer1 ~users/
HOSTS: all
</pre>

'''Note:'''
* users group entry in /etc/group must define a list of 'user' in this users group, ie: users:100:userX. Otherwise, 'badmin reconfig' will fail. It is not enough just do 'useradd userX -g 100'
