HP XC System Software Installation Guide Version 3.1

Do one of the following:
• To install LSF-HPC with SLURM or standard LSF, enter y or press the Enter key. Proceed to
step 15.
• If you intend to install another job management system, such as PBS Professional (documented
in Appendix L (page 177)) or the Maui Scheduler (Appendix M (page 183)) enter n. Proceed to
step 20.
If at a future time you want to install LSF, rerun the cluster_config utility, and answer y to
this question.
The remainder of this procedure does not describe how to install any other job management
system other than LSF-HPC with SLURM or standard LSF.
15. Decide what type of LSF to install, if any:
There are two types of LSF available to install:
1. Standard LSF: the standard Load Sharing Facility product.
2. LSF-HPC integrated with SLURM: the LSF High Performance
Computing solution integrated with SLURM for XC.
Which LSF product would you like to install (1/2)? [2]:
Table 3-8 describes characteristics of LSF-HPC with SLURM and standard LSF to help you decide the
type of LSF to install.
Table 3-8 Characteristics of LSF-HPC with SLURM and Standard LSF
Standard LSFLSF-HPC with SLURM
• Ideal for serial jobs because it is a load-based scheduler
• Finds the free resource that is the least loaded and
dispatches the job to that node.
• Sufficient for sites that do not need the type of parallel job
support provided by LSF-HPC with SLURM.
• Parallel support (through SLURM) for:
— Accounting
— Signal propagation
— I/O
— Job launching
• Designed to ensure that parallel jobs (MPI jobs) achieve
the best performance by dedicating whole nodes to parallel
jobs. This works well for systems with 2 processor and 4
processor nodes where jobs are expected to span across
nodes.
• Exclusive node allocation with exclusive user access
control.
• Presents the entire system as a single, large SMP host rather
than a large system of many hosts. This simplifies system
status commands because information is shown for one
host, which makes it desirable for large-scale systems.
16. If you are installing LSF-HPC with SLURM, your first decision is where to assign the primary LSF
node; this decision is not required for standard LSF.
• If more than one node has the resource_management role, you are prompted to identify the
primary LSF node, as follows:
Here is the set of nodes from which to select the Primary
XC LSF-HPC node: n[15-16]
Enter the Primary XC LSF-HPC node [n16] : n16
• If only one node has the resource_management role, the following is displayed:
n16 is the only node with the Resource Management role,
and it is the Primary LSF-HPC node.
