Ensure That LSF-HPC with SLURM Is Not Activated
HP does not support the use of the Maui Scheduler with LSF-HPC 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-HPC with SLURM is not activated on the system. If LSF-HPC with SLURM is
activated, you must deactivate it before proceeding.
The following procedure describes how to determine if LSF-HPC 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...
10.4 Installing the Maui Scheduler
Before starting this procedure, follow the recommendations in “Preparing for the Installation”
(page 157). 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:
http://www.llnl.gov/linux/slurm/maui.html
The following summarizes the steps to install and configure the Maui Scheduler to work with
SLURM on an HP XC system:
• “Task 1: Download the Maui Scheduler Kit” (page 159)
• “Task 2: Compile the Maui Scheduler from Its Source Distribution” (page 159)
• “Task 3: Update the Maui Scheduler Configuration File” (page 159)
