How to assign maximum cores to particular queue?

[zainul1114]

Hi Team,
We are using pbs_version = 19.1.1,

Please help us to explain the details for below scenario’s

We have two nodes with 16 cores each, Totally 32cores and We have 3 Departments.

1. How can we assign max 8cores to each Dept (D1, D2 and D3) remaining 8cores will be free. (Please clarify us, can we think department nothing but Queue)
2. How to control a user to submit only assigned dept (D1)
3. How to list assigned cores with respect to Dept(D1) and Node(cores from which node)
4. How to assign complete node to particular Dept (D1)
5. How to submit priority job with maximum cores (around 30cores)
6. Limit the maximum number of running cores (4) for all users in a dept(D1)

Regrads,
Zain

Please make sure

1. Please check this documentation on Server and Queue limits
   https://www.altair.com/pdfs/pbsworks/PBSAdminGuide2020.1.pdf
   The below section in the documentation has all the examples:
   5.15.1.9.ii Examples of Setting Server and Queue Limits

2. You can acl_users / acl_groups to control which queues the users are allowed to submit jobs.
   Also, you can have fine grained custom control by implementing queuejob hook
   in the above guide: search for acl_users , acl_groups , queuejob hook

3. You need need to write a json parser script, that would parse the output of qstat -fx -F json and get the desired results .

4. You can use Qlist set. Check the documentation and example at
   4.9.2.2.i Procedure to Associate Vnodes with Multiple Queues

5. You can use job sort formula to sort the jobs in which they get scheduled with ncpus has one fo the factor. In the above guide: check job_sort_formula and examples

6. Please check this documentation on Server and Queue limits
