HP XC System Software Installation Guide Version 3.0

Ensure That LSF Is Not Activated
HP does not support the use of the Maui Scheduler with LSF. 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
is not activated on your system. If LSF is activated, you must deactivate it before proceeding.
The following procedure describes how to determine if LSF is activated and running on your system, and
how to deactivate it. Deactivating LSF consists of first stopping the LSF service if it is running and then disabling
it.
1. Determine if the LSF service is running on your system:
# controllsf status
This command returns either up (running) or down (not running).
• If the LSF service is running, perform step 2 to stop the service, then step 3 to disable LSF on the
system.
• If the LSF service is not running, perform step 3 to disable LSF on the system.
2. Stop the LSF service by issuing the following command from the head node:
# service lsf stop
3. Disable LSF by issuing the following command from the head node:
# 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 your 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...
Installation Procedure
Before starting this procedure, follow the recommendations in “Before You Begin” (page 135). When performing
this procedure, it may 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 may be helpful to review the information on the SLURM Maui Web site at:
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:
1. Task 1: Download the Maui Scheduler Kit (page 136)
2. Task 2: Compile the Maui Scheduler from Its Source Distribution (page 137)
3. Task 3: Update the Maui Scheduler Configuration File (page 137)
4. Task 4: Edit the SLURM Configuration File (page 137)
5. Task 5: Configure the Maui Scheduler (page 137)
Task 1: Download the Maui Scheduler Kit
Follow this procedure to download the Maui Scheduler kit:
1. Log in as the root user on the head node.
2. Download the Maui Scheduler kit to a convenient directory on the system. The Maui Scheduler kit is
called maui-3.2.6p9, and it is available at:
