Glossary

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

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.

For Basic Input/Output System. It typically contains 
code for initial hardware setup and bootstrapping.

A machine on which source code, examples or 
benchmarks can be compiled.

A machine used to run a job.

For Direct Access Provider Library. The reference 
implementation for RDMA transports. Consists of both 
kernel mode (kDAPL) and user mode (uDAPL) 
versions.

Same as build node.

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.

For Extended Advanced Technology Extended 
motherboard.

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.

The machine or machines used to launch jobs.

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.
