15.3.4 Interactive Simulation Tutorial

This of this section provides an interactive tutorial to demonstrate the basics of the simulator's capacities in Moab. It is an example of what you can do once you have set up simulation. The commands to issue are formatted as follows: > showq along with the expected output.

The following commands are used:

• showq [-r] [-i]
• showstats [-g] [-u] [-v]
• mschedctl -l
• mschedctl [{-s|-S} [I]] [-k]
• checkjob
• mschedctl -m
• mdiag -n
• showres [-n jobid]
• setres

To run through the simulation mode tutorial

1. Run moab.

   > moab&

2. Check the status of the queue (see Checking the Queue Status).
3. Check the status of the job. If any jobs are not running, find the problem (see Determining Why Jobs Are Not Running).
4. Advance and check the status of Moab iterations and time in simulation mode (see Controlling Iterations).
5. View and manage reservations and their nodes and jobs (see Managing Reservations Applying to the Queue).
6. Verify that the Moab simulation is scheduling fairly (see Verifying Fair Scheduling).
7. Take down the entire system for maintenance (see Taking the System Down for Maintenance).
