Q

MTRR

For Memory Type Range Registers. MTRR For

 

"Memory Type Range Registers". Used by the

 

InfiniPath driver to enable write combining to the

 

InfiniPath on-chip transmit buffers. This improves write

 

bandwidth to the InfiniPath chip, by writing multiple

 

words in a single bus transaction (typically 64). Applies

 

only to x86_64 systems.

MTU

For Maximum Transfer Unit. The largest packet size

 

that can be transmitted over a given network.

multicast group

A mechanism that a group of nodes use to

 

communicate amongst either other. It is an efficient

 

mechanism for broadcasting messages to many nodes,

 

as messages sent to the group are received by all

 

members of the group without the sender having to

 

explicitly send it to each individual member (or even

 

having to know who the members are.) Nodes can join

 

or leave the group at any time.

node file

Same as hostsfile.

node program

Each individual process that is part of the parallel MPI

 

job. The machine on which it is executed is called a

 

node.

OpenIB

The previous name of OpenFabrics.

OpenFabrics

The open source InfiniBand protocol stack.

OpenMP

Specification that provides an open source model for

 

parallel programming that is portable across shared

 

memory architectures from different vendors.

OpenSM

Open source SM (Subnet Manager) that provides basic

 

functionality for subnet discovery and activation.

PCIe

For PCI Express. Based on PCI concepts and

 

standards, PCIe uses a faster serial connection

 

mechanism.

RDMA

For Remote Direct Memory Access. A communications

 

protocol that enables data transmission from the

 

memory of one computer to the memory of another

 

without involving the CPU. The most common form of

 

RDMA is over InfiniBand.

RPM

For Red Hat Package Manager. A tool for packaging,

 

installing, and managing software for Linux

 

distributions.
