Ensure That LSF with SLURM Is Not Activated
HP does not support the use of the Maui Scheduler with LSF with SLURM. These schedulers
have not been integrated and will not work together on an HP XC system.
Before you install the Maui Scheduler on an HP XC system, you must be sure that the HP XC
version of LSF with SLURM is not activated on the system. If LSF with SLURM is activated, you
must deactivate it before proceeding.
The following procedure describes how to determine if LSF with SLURM is activated and running
on the system and how to deactivate it. Deactivating LSF consists of first stopping the LSF service
and then disabling it.
1. From the head node, determine if LSF is installed on the system:
# which lsid
This command fails if LSF is not installed.
2. If the lsid binary is found, ensure that LSF is not running:
# lsid
• If the LSF service is running, perform step 3 to stop the service, then step 4 to disable
LSF on the system.
• If the LSF service is not running, perform step 4 to disable LSF on the system.
3. Stop the LSF service:
# pdsh -a /sbin/service lsf stop
4. Disable LSF:
# pdsh -a /sbin/chkconfig lsf off
Ensure That SLURM Is Installed and Running on the System
SLURM must be installed and running on the system before you install the Maui Scheduler.
Enter the following command to verify that SLURM is running on the system:
# pdsh -a service slurm status
n15: slurmd (pid 2682) is running...
n14: slurmd (pid 2372) is running...
n16: slurmctld (pid 3111) is running...
n16: slurmd (pid 3120) is running...
12.4 Installing the Maui Scheduler
Before starting this procedure, follow the recommendations in Section 12.3 (page 165). When
performing this procedure, it might be useful to have the Maui Scheduler Administrator’s Guide
available. The Maui Scheduler Administrator’s Guide has a section called “Building and Installing
Maui” which is very useful. You can find this guide at:
http://www.clusterresources.com/products/maui/docs/mauiadmin.shtml
In addition, it might be helpful to review the information on the SLURM Maui website:
https://computing.llnl.gov/linux/slurm/maui.html
The following summarizes the steps required to install and configure the Maui Scheduler to
work with SLURM on an HP XC system:
• “Download the Maui Scheduler Kit” (page 167)
• “Compile the Maui Scheduler from Its Source Distribution” (page 167)
• “Update the Maui Scheduler Configuration File” (page 167)
• “Edit the SLURM Configuration File” (page 168)
• “Configure the Maui Scheduler” (page 168)
