HP XC System Software Installation Guide Version 4.0

NOTE: After cluster_config processing is complete, you have the option to modify
default SLURM compute node and partition information, as described in Section 7.1.1
(page 123).
19. Define a SLURM user name and accept all default responses.
NOTE: The output looks different if you assigned the resource_management role to
one or more nodes because you will be prompted to assign the master and backup controller
nodes. This command example does not show that prompt.
This SLURM configuration needs a special SLURM user. The SLURM
controller daemons will be run by this user, and certain SLURM
runtime files will be owned by this user.
Enter the SLURM username [slurm]: Enter
User 'slurm' does not exist.
If this user account is created here, it will not have login
access. Do you want to create this user? (y/n) [y]: Enter
n16 is the only node with the Resource Management
role. Therefore the SLURM Master Controller daemon will be set up
on this node, and there will be no SLURM Backup Controller.
The current Compute Node configuration is:
NodeName=n[11-16] Procs=2
NOTE: The only Partition created by default is the xc
partition. If you want additional partitions, configure
them manually in the /hptc_cluster/slurm/etc/slurm.conf file.
The current Node Partition configuration is:
PartitionName=xc Default=YES Nodes=n[14-16]
Do you want to enable SLURM-controlled user-access to the
compute nodes? (y/n) [n]: n

SLURM configuration complete. Press 'Enter' to continue: Enter
Executing C91swmlogger gconfigure
Executing C95lsf gconfigure

By default, all compute nodes in the HP XC system are accessible by any user after
their user accounts have been set up. This prompt enables you to restrict individual
access to each compute node to the user who currently has the compute node
reserved within SLURM.
It is important that you assign a login role to each node on which you expect users
to be able to log in and use the system. If you answer yes here and configure all
nodes with the compute role (the default), but you do not configure any nodes with
the login role, non-root users will not be allowed to log in to the system.
20. Decide whether you want to install LSF as the job management system:
Do you want to install LSF now? (y|n) [y]:
Do one of the following:
• To install LSF, enter y or press the Enter key.
— If you elected to install SLURM, proceed to step 21 to choose the type of LSF to
install.
— If you did not elect to install SLURM, you cannot choose the type of LSF to install,
and standard LSF is installed automatically. Proceed to step 23.
