HP XC System Software Hardware Preparation 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 installation, the head node acts as the image server and golden client.
Integrated Lights Out
See iLO
interconnect
Provides high-speed connectivity b etween the nodes. It is used for message passing and remote
memory access capabilities for parallel applications.
interconnect network
The private network within the X C system that is used primarily for user f ile access and for
communications within applications.
Internet address
A unique 32-bit number that identifies a h ost’s connection to an Internet netwo rk. An Internet
address is commonly represented as a netwo rk number and a host number and takes a fo rm
similar to the following: 192.168.0.1.
I/O node
A node that has more storage av ailable than the majority of server no des in a n XC system.
This storage is frequently externally connected storage, for example, SAN attached storage.
When configured properly, an I/O server node makes the addition a l stor age available as global
storage within the XC system.
IPMI
Intelligent Platform Management 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 Server
See LVS
load file
A file containing the nam es of m ultiple executables that are to be launched simultaneously by
a single command.
Load Sharing Facility
See LSF
local storage
Storage that is available or accessible from one node in the XC system.
LSF
Load Sharing F acility. The batch system resource m anager 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, wh ich is the total number of processors designated for batch processing.
LSF can also run interactive batch jobs and interactive jobs. A n LSF interactive batch job
allows you to interact with the application wh ile still taking advantage of LSF scheduling
policies and features. An LSF interactive job is run without using LSF batch processing features
but is dispatched immediately by LSF on the LSF execution host.
See also LSF execution host
LSF execution host
The node where LSF runs. A users job is su bmitted to the LSF execution host. Jobs are
launched from the LSF execution host and are executed on one or more compute nodes.
