Glossary

A glossary is provided below for technical terms used in the documentation.

bandwidth

The rate at which data can be transmitted. This

 

represents the capacity of the network connection.

 

Theoretical peak bandwidth is fixed, but the effective

 

bandwidth, the ideal rate is modified by overhead in

 

hardware and the computer operating system. Usually

 

measured in bits/megabits or bytes/megabytes per

 

second. Bandwidth is related to latency.

BIOS

For Basic Input/Output System. It typically contains

 

code for initial hardware setup and bootstrapping.

build node

A machine on which source code, examples or

 

benchmarks can be compiled.

compute node

A machine used to run a job.

DAPL

For Direct Access Provider Library. The reference

 

implementation for RDMA transports. Consists of both

 

kernel mode (kDAPL) and user mode (uDAPL)

 

versions.

development node

Same as build node.

DHCP

For Dynamic Host Configuration Protocol. A

 

communications protocol for allocating IP addresses.

 

Also provides other basic networking information, such

 

as router addresses and name servers.

EATX

For Extended Advanced Technology Extended

 

motherboard.

fabric

The InfiniBand interconnect infrastructure, consisting

 

of a set of HCAs (and possibly TCAs) connected by

 

switches, such that each end node can directly reach

 

all other nodes.

front end node

The machine or machines used to launch jobs.

funneled thread model

Only the main (master) thread may execute MPI calls.

 

In InfiniPath MPI, hybrid MPI/OpenMP applications are

 

supported, provided the MPI routines are called only by

 

the master OpenMP thread.
