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

We have two nodes(smaster, snode) with 16 cores each, Totally 32cores and
We have 3 Departments with 4 Students each.
1. How to create a cluster (ex: hpcc)
2. How to create an account(D1) and add to a specific cluster(hpcc).
3. How to create a user(d1user1) and assign to specific account(D1)
4. How can we assign maximum 8cores to each Dept (D1, D2 and D3)
5. How to control a user to submit only assigned dept (D1)
6. How to list assigned cores with respect to Dept(D1) and Node(cores from
which node)
7. How to assign complete nodes to particular Dept (D1)
8. How to submit priority job with maximum cores and maximum time (around
30cores)
9. Limit the maximum number of running cores (4) for all users in a dept(D1)
10. How to assign a user to run jobs in multiple departments like two
departments (D1,D2)
