HP XC System Software Installation Guide Version 2.1

image server
A node specifically designated to hold images that will be distributed to one or mo re client
systems. In a standard XC i nstallation, the head node acts as the image server and golden client.
Integrated Lights Out
See iLO
interconnect
Provides high-speed connectivity between the nodes. It is used for message passing and remote
memory access capabilities for parallel applications.
interconnect network
The private network within the XC system that is used primarily for user file access and for
communications within applications.
Internet address
A unique 32-bit number that identifies a host’s connection to an Internet network. An Internet
address is commonly represented as a netwo rk number and a host number and takes a form
similar to the following: 192.168.0.1.
I/O node
A nod e that has more storage available than the majority o f server nodes in an XC system.
This storage is f requently externally connected storage, for example, S AN attached storage.
When configured properly, an I/O server nod e makes the additional s tor age avail a ble as global
storage within the XC system .
IPMI
Intelligent Platform Managem ent Interface. A self-contained hardware technology available on
HP ProLiant DL145 servers that allows remote management of any node within a system.
L
Linux Virtual Serv er
See LVS
load file
A file containing the names of multiple executables that are to be launched simultaneously by
a single comm and.
Load Sharing Facility
See LSF HPC
local storage
Storage that is available or accessible from one node in the XC system.
LSF HPC
Load Sharing Facility for High Performance Computing. The batch system resource manager
on an HP XC system . LSF HPC places a job in a q ueue and allows it to run when the necessary
resources becom e available. LSF H PC man ages just one resource, which is the total numb er of
processors designated for batch processing.
LSF HPC can also run interactive batch jobs and interactive jobs. A n LSF interactive batch job
allows you to interact with the applicatio n whil e still taking advantage of LSF HPC schedu ling
policies and features. An L SF HPC interactive job is run without using LSF H PC b atch
processing featu res but is dispatched immediately by LSF HPC on the LSF execution host.
See also LSF execution host
LSF execution host
The node where LSF runs. A u ser’s job is submitted to the LSF execution host. Jobs are
launched from the LSF execution host and are executed on one or more compute nodes.
