image server

A node specifically designated to hold images that will be distributed to one or more client

 

systems. In a standard HP XC installation, the head node acts as the image server and golden

 

client.

improved

A service availability infrastructure that is built into the HP XC system software to enable an

availability

availability tool to fail over a subset of eligible services to nodes that have been designated as

 

a second server of the service

 

See also availability set, availability tool.

Integrated Lights

See iLO.

interconnect

A hardware component that provides high-speed connectivity between the nodes in the HP

 

XC system. It is used for message passing and remote memory access capabilities for parallel

 

applications.

interconnect

A module in an HP BladeSystem server. The interconnect module provides the Physical I/O

module

ports for the server blades and can be either a switch, with connections to each of the server

 

blades and some number of external ports, it can be or a pass-through module, with individual

 

external ports for each of the server blades.

 

See also server blade.

interconnect

The private network within the HP XC system that is used primarily for user file access and

network

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 network number and a host number and takes a form

 

similar to the following: 192.0.2.0.

IPMI

Intelligent Platform Management Interface. A self-contained hardware technology available

 

on HP ProLiant DL145 servers that enables remote management of any node within a system.

ITRC

HP IT Resource Center. The HP corporate Web page where software patches are made available.

 

The web address is http://www.itrc.hp.com. To download patches from this Web page, you

 

must register as an Americas/Asia Pacific or European customer.

Linux Virtual

See LVS.

Server

 

load file

A file containing the names of multiple executables that are to be launched simultaneously by

 

a single command.

Load Sharing

See LSF-HPC with SLURM.

Facility

 

local storage

Storage that is available or accessible from one node in the HP XC system.

LSF execution

The node on which LSF runs. A user's job is submitted to the LSF execution host. Jobs are

host

launched from the LSF execution host and are executed on one or more compute nodes.

LSF master host

The overall LSF coordinator for the system. The master load information manager (LIM) and

 

master batch daemon (mbatchd) run on the LSF master host. Each system has one master host

 

to do all job scheduling and dispatch. If the master host goes down, another LSF server in the

 

system becomes the master host.

LSF-HPC with

Load Sharing Facility for High Performance Computing integrated with SLURM. The batch

SLURM

system resource manager on an HP XC system that is integrated with SLURM. LSF-HPC with

 

SLURM places a job in a queue and allows it to run when the necessary resources become

 

available. LSF-HPC with SLURM manages just one resource: the total number of processors

 

designated for batch processing.

 

LSF-HPC with SLURM can also run interactive batch jobs and interactive jobs. An LSF interactive

 

batch job allows you to interact with the application while still taking advantage of LSF-HPC

 

with SLURM scheduling policies and features. An LSF-HPC with SLURM interactive job is run

 

without using LSF-HPC with SLURM batch processing features but is dispatched immediately

 

by LSF-HPC with SLURM on the LSF execution host.
