HP XC System Software Installation Guide Version 3.0

After cluster_config processing is complete, you have the option to modify default SLURM compute
node and partition information. This information is described in “Task 8: Modify SLURM Characteristics
(Optional)” (page 59).
8. Decide whether or not you want to install LSF as your job management system:
Do you want to install LSF locally now? (y|n) [y]:
Do one of the following:
• To install LSF-HPC with SLURM or standard LSF, enter y or press the Enter key. Proceed to step
9.
• If you intend to install another job management system, such as the Maui Scheduler (which is
documented in Appendix J (page 135)), enter n. Proceed to step 12.
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.
9. Decide the type of LSF to install:
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 4-6 describes characteristics of LSF-HPC with SLURM and standard SLURM to help you decide
which type of LSF to install.
Table 4-6 Characteristics of LSF-HPC with SLURM and Standard LSF
Standard LSFLSF-HPC With SLURM
•• A load-based scheduler, which is ideal for serial jobs.Parallel support for:
• Accounting
• Finds the free resource that is the least loaded and dispatches
the job to that node.
• Signal propagation
• Sufficient for sites that do not need the type of parallel job
support provided by LSF-HPC with SLURM.
• 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.
10. 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 is assigned 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 is assigned 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.
