HP XC System Software Installation Guide Version 4.0

• If you intend to install another job management system, such as PBS Professional (see
Chapter 11 (page 159)) or the Maui Scheduler (see Chapter 12 (page 165)) enter n. Proceed
to step 25.
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 with SLURM or standard LSF.
21. Decide what type of LSF to install:
There are two types of LSF available to install:
1. Standard LSF: the standard Load Sharing Facility product.
1
2. LSF 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]:
1
If you install standard LSF, you are prompted to install the standard LSF (high
performance computing) extensions. These extensions include MPI and mpich
features.
Table 6-3 lists the features of LSF with SLURM and standard LSF to help you decide the
type of LSF to install.
Table 6-3 LSF with SLURM and Standard LSF Features
Standard LSFLSF 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 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.
22. If you are installing LSF 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 node: n[15-16]
Enter the Primary XC LSF node [n16] : n16
• If only one node has the resource_management role, the following appears:
n16 is the only node with the Resource Management role,
and it is the Primary LSF node.
