Glossary

This glossary conforms to the CIWG (Compliance Interoperability

Workgroup).

A

Analyzer

An abstract description of test equipment that passively observes signals

on a link in support of response checking. Analyzers have different

capabilities, ranging from detailed observation of electrical signals to

observation of packets. An ideal analyzer records the entire history of

activity it observes.

C

Capability

An abstract definition of test equipment functionality. Capabilities are

used to implement response checking for test descriptions as well as to

specify stimulus generation. Capabilities are expressed as action phrases

with optional modifiers that parameterize the action.

Component

A device in a topology definition. Examples of components include a

switch, an endnode, or a cable.

Device Under Test (DUT)

The component that is the target of stimulus and whose responses are

checked as specified in a Test Description.

Endnode

An endnode is any node that contains a Channel Adapter and thus has

multiple queue pairs and is permitted to establish connections, end-to-

end context, and to generate messages. Functional capabilities of an

endnode are a superset of those of an endpoint. For the purpose of

defining topologies, Port 0 of a switch is considered an endnode in that it

consumes and generates MADs.

Endpoint

A node at the end of the link that is capable of maintaining the link state

and sends or receives packets but does not source or sink any InfiniBand

protocol data units. A switch is an example of an endpoint.
