M.4.5 Task 5: Configure the Maui Scheduler
After you install and set up the Maui Scheduler to interoperate with SLURM on HP XC, you must perform
the standard Maui Scheduler configuration steps. The configuration is complicated and is beyond the
scope of this document. The best resource for configuring the Maui Scheduler is the online information
available at the Maui Scheduler developer's Web site, which is located at:
http://www.supercluster.org
M.5 Verify Successful Installation of the Maui Scheduler
You can verify the success of the Maui Scheduler installation and configuration by executing various Maui
Scheduler commands.
Maui Scheduler commands such as showq, showstate, checknode, and checkjob can help you to
determine if the Maui Scheduler is operating properly on the system.
For example, you could verify Maui Scheduler operations by launching a job and using the following
commands:
• Show the state of the queue and other job and reservation data structures:
root@n16: showq
