host availability for a user with limits consideration

Question

Say I have a host with 10 slotsn I have applied a user limit to that host as following: SLOT = 5 JOB = 3

Is there a command to find whether this host can run more jobs from that user? OR, Is there a command to find whether the said host is closed for the said user.

Thanks in advance!

Answer 1

Taking your description of your limit, I imagine its definition looks something like this:

Begin Limit
NAME = L1
USERS = user1
SLOTS = 5
JOBS = 3
HOSTS = hostA
End Limit

If I then submit 3 jobs as user1, I can run the blimits -u user1 to see if there are any limits imposed on the user1, or blimits -m hostA to see if there are any limits relevant to hostA. I can also combine these filters to see if there are any relevant limits imposed on user1 on hostA:

$ blimits -u user1 -m hostA

    INTERNAL RESOURCE LIMITS:

        NAME          USERS            QUEUES           HOSTS           PROJECTS      SLOTS     MEM      TMP      SWP      JOBS
         L1           user1              -              hostA              -           3/5       -        -        -       3/3

The last column of this output (JOBS) shows me that this user has reached his limit for jobs on that host (running 3 jobs out of a possible 3 allowed).
