HP XC System Software Hardware Preparation Guide Version 3.1

PXE Preboot Execution Environment. A standard client/server interface that enables networked
computers that are not yet installed with an operating system to be configured and booted
remotely. PXE booting is configured at the BIOS level.
R
resource
management role
Nodes with this role manage the allocation of resources to user applications.
role A set of services that are assigned to a node.
Root
Administration
Switch
A component of the administration network. The top switch in the administration network; it
may be a logical network switch comprised of multiple hardware switches. The Root Console
Switch is connected to the Root Administration Switch.
root node A node within an HP XC system that is connected directly to the Root Administration Switch.
RPM Red Hat Package Manager.
1. A utility that is used for software package management on a Linux operating system, most
notably to install and remove software packages.
2. A software package that is capable of being installed or removed with the RPM software
package management utility.
S
serial application A command or user program that does not use any distributed shared-memory form of
parallelism. A serial application is basically a single-processor application that has no
communication library calls (for example, MPI, PVM, GM, or Portals).
An example of a serial application is a standard Linux command, such as the ls command.
Another example of a serial application is a program that has been built on a Linux system that
is binary compatible with the HP XC environment, but does not contain any of the HP XC
infrastructure libraries.
server blade One of the modules of an HP BladeSystem. The server blade is the compute module consisting
of the CPU, memory, I/O modules and other supporting hardware. Server blades do not contain
their own physical I/O ports, power supplies, or cooling.
SLURM backup
controller
The node on which the optional backup slurmctld daemon runs. On SLURM failover, this
node becomes the SLURM master controller.
SLURM master
controller
The node on which the slurmctld daemon runs.
SMP Symmetric multiprocessing. A system with two or more CPUs that share equal (symmetric)
access to all of the facilities of a computer system, such as the memory and I/O subsystems. In
an HP XC system, the use of SMP technology increases the number of CPUs (amount of
computational power) available per unit of space.
ssh Secure Shell. A shell program for logging in to and executing commands on a remote computer.
It can provide secure encrypted communications between two untrusted hosts over an insecure
network.
standard LSF A workload manager for any kind of batch job. Standard LSF features comprehensive workload
management policies in addition to simple first-come, first-serve scheduling (fairshare,
preemption, backfill, advance reservation, service-level agreement, and so on). Standard LSF
is suited for jobs that do not have complex parallel computational needs and is ideal for
processing serial, single-process jobs. Standard LSF is not integrated with SLURM.
