Q

E – Glossary

LID

For Local Identifier. Assigned by the Subnet Manager

 

(SM) to each visible node within a single InfiniBand

 

fabric. It is similar conceptually to an IP address for

 

TCP/IP.

Lustre

Open source project to develop scalable cluster file

 

systems.

MAC Address

For Media Access Control Address. It is a unique

 

identifier attached to most forms of networking

 

equipment.

machines file

Same as mpihostsfile.

MADs

For Management Datagrams. Subnet Managers (SMs)

 

and Subnet Management Agents (SMAs)

 

communicate via MADs.

managed switch

A switch that can be configured to run an embedded

 

Subnet Manager (SM).

MGID

For Multicast Group ID. An identifier for a multicast

 

group. This can be assigned by the SM at multicast

 

group creation time, although frequently it is chosen by

 

the application or protocol instead.

MLID

For Multicast Local ID for InfiniBand multicast. This is

 

the identifier a member of a multicast group uses for

 

addressing messages to other members of the group.

MPD

For Multi-Purpose Daemon. An alternative to mpirun

 

to launch MPI jobs, providing support for MPICH.

 

Developed at Argonne National laboratory.

MPI

For Message-Passing Interface. MPI is a

 

message-passing library or collection of routines used

 

in distributed-memory parallel programming. It is used

 

in data exchange and task synchronization between

 

processes. The goal of MPI is to provide portability and

 

efficient implementation across different platforms and

 

architectures.

MPICH

A freely available, portable implementation of MPI.

mpihosts file

A file containing a list of the hostnames of the nodes in

 

a cluster on which node programs may be run. Also

 

referred to as node file, hosts file, or machine(s) file.
