HP XC System Software Administration 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
The private network w ithin the XC system that is used p rimarily for user f ile access and for
communications within applications.
interconnect
Provides high-speed connectivity b etween the nodes. It is used for message passing and remote
memory access capabilities for parallel applications.
Internet address
A unique 32-bit number that identifies a host’s connection to an Internet netwo rk. An Internet
address is commonly r epresen ted as a network number and a host number and takes a fo rm
similar to the following: 192.168.0.1.
I/O node
A nod e that has more storage av a ilab le than the majority of server nodes in an XC system .
This storage is frequently externally connected storage, for example, SAN attached storage.
When configured properly, an I/O server node makes the a dditional s tor a ge availa ble as glo bal
storage within the XC system.
IPMI
Intelligent Platform Management Interface. A self-contained hardware technology available on
HP ProLiant DL145 servers that allows remote man agement of any node within a system.
L
Linux Virtual Server
See LVS
load file
A file containing the names of multiple executables that are to be launched simultaneously by
a single comma nd.
Load Sharing Facility
See LSF
local storage
Storage that is available or accessible from one node in the XC system.
LSF
Load Sharing Facility. The batch system resource manager on an HP XC system. LSF places a
job in a queue and allows it to run when the necessary resources become available. LSF manages
just one resource, which is the total number of processors designated for batch processing.
LSF can also run i nteractive batch jobs and interactive jobs. A n LSF interactive batch job
allows you to interact with the application while still taking advantage of LSF scheduling
policies and features. An L SF interactive job is run without usin g LSF batch processing features
but is dispatched immediately by LSF on the LSF ex ecution host.
See also LSF execution host
LSF execution host
The node where LSF runs. A user’s job is submitted to the LSF execution host. Jobs are
launched from the LSF execution host and are executed on one or more com pute nodes.
