Glossary

distributed application

The same application that runs independently o n several nodes, possibly

with different input parameters. There is no communication, shared

data, or synchronization points betwe en the nodes, so they are generally

considered to be coarse-grained.

distributed array

An array partitioned into segments, with each segment residing in the

workspace of a different worker.

DNS

Domain Name System. A system that translates Inte rne t domain

names into IP a ddre sses.

dynamic licensing

The ability of a MATLAB worker to employ all the functionality you are

licensed for in the MA TLAB client, while checking out only an engine

license. When a job is created in the MATLAB client with Parallel

ComputingToolboxsoftware,theproducts for which the client is licensed

will be available for all workers that evaluate tasks for that job. This

allows you to run any code on the cluster that you are licensed for on your

MATLAB client, without requiring extra licenses for the worker beyond

MATLAB Distributed Computing Server software. For a list of products

that are not eligible fo r use with Parallel Computing Toolbox software,

see

http://www.mathworks.com/products/ineligible_programs/.

fine-grained application

An application for which r u n time is significantly less than the

communication time needed to start and stop the program. Compare to

coarse-grain ed applications.

head node

Usually, the node of the cluster designated for running the job scheduler

and license manager. It is often useful to run all the nonworker related

processes on a single machine.

heterogeneous cluster

A cluster that is not hom og eneous.
