HP XC System Software Administration Guide Version 3.2

Note:
The root-only lsf partition is provided for submitting and managing jobs through an interaction
of SLURM and LSF. If you intend to use SLURM independently from LSF, consider configuring
a separate SLURM partition for that purpose.
Table 15-2 describes the SLURM partition characteristics available on HP XC systems.
Table 15-2 SLURM Partition Characteristics
DescriptionCharacteristic
List of nodes that constitute this partition.
Nodes
A comma-separated list of group IDs that are allowed to use the
partition.
The default is ALL, which allows all users to access the partition.
AllowGroups
A text string, which must be either YES or NO.
The value YES indicates that the corresponding partition is the
default when users submit jobs without specifying a partition.
Default
A text string, which must be either YES or NO.
The text string YES specifies that only the superuser (root) can use
this partition.
RootOnly
Specifies the maximum count of nodes that can be allocated to any
single job.
The default is unlimited or -1.
MaxNodes
Specifies the maximum time limit (in minutes) allowed for jobs in
this partition.
The default is unlimited or -1.
MaxTime
Specifies the minimum number of nodes that can be allocated to
any single job.
The default is 1.
MinNodes
A text string that indicates whether node sharing for jobs is allowed:
YES
The node may be shared or not, depending on the
allocation.
FORCE
The node is always available to be shared.
NO
The node is never available to be shared.
Shared
The state of the partition.
The possible values are UP or DOWN.
State
Consider a system that has 128 nodes. The following line in the
/hptc_cluster/slurm/etc/slurm.conf file indicates that partition lsf controls all 128
nodes:
PartitionName=lsf RootOnly=yes Shared=FORCE Nodes=n[1-128]
However, you might prefer not to run jobs on the head node, n128. Simply modify the line to
the following:
PartitionName=lsf RootOnly=yes Shared=FORCE Nodes=n[1-127]
Consider an academic system with 256 nodes. Suppose you would like to allocate half the system
for faculty use and half for student use. Furthermore, the faculty prefers the order and control
imposed by LSF, while the students prefer to use the srun command. You might set up your
partitions as follows:
