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.
