See CHECKPOINTB ASE.

client

The MATLAB session that defines and submits the job. This is the

MATLAB s ession in w hich the programmer usually develops and

prototypes applications. Also known as the MATLAB client.

client computer

The computer running the MATLAB client; often your desktop.

cluster

A c ol lection o f computers that are connected via a network and intended

for a common purpose.

coarse-grained application

An application for which run time is significantly greater than

the communication time needed to start and stop the program.

Coarse-grained distributed a pplications are also called embarrassingly

parallel applications.

communicating job

Job composed of tasks that communicate with each other during

evaluation. All tasks must run simultaneously. A special case of

communicating job is a parallel pool, used for executing

parfor-loops

and

spmd blocks.

Composite

An object in a MATLAB client session that provides access to data

values store d on the workers in a parallel pool, such as the values of

variables that are assigned inside an

spmd statement.

computer
