Thread: Slot Restrictions for Individual User

Originally posted by: JPummill, Fri Jan 12, 2007 3:19 pm

I need to be able to assign a slot limit for a user (users) on an individual basis as we are about to start using one of our appliances for a teaching tool during the spring semester. I have one user who keeps the queue full of jobs (and I appreciate this ), but for the semester, I need to cut back the slots available to her so that half of the cluster is free for the class.

Easy mod?

There are several ways to keep one user from hogging all the job slots in LSF. Here's one way to do it...

Edit lsb.resources, add a "limit". Here's an example, using "vertical tabular format":

Begin Limit
USERS QUEUES HOSTS SLOTS
shirley normal - 5
fred - hostA 2
jane - - 4
End Limit

This would limit user "shirley" to only 5 job slots at a time in the "normal"
queue, regardless of what host she's running on. It also limits user "fred" to only 2 slots at a time on "hostA", regardless of which queue. And "jane" is limited to 4 slots at a time, no matter what queue(s) or host(s).

The man page for lsb.resources shows some other examples of this.

Hope this helps,
Dale
