Glossary
distributed computing
Computing with distributed applications, running the application on
several nodes simultaneously.
distributed computing demo s
Demonstration p rog rams that use Distributed Computing Toolbox, as
opposed to sequential demos.
DNS
Domain Name System. A system that translates Internet domain
names into IP addresses.
dynamic licensing
The ability of a MATLAB worker or lab to employ all the functionality
you are licensed for in the MATLAB client, while checking out
only an engine license. When a job is created in the MATLAB
client with Distributed C omputing Toolbox, the products for which
the client is licensed will be availabl e for all workers or labs that
evaluate tasks for that job. This allows you to run any c o de on
the cluster that you are licensed for on your MATLAB client,
without requiring extra licenses for the worker beyond MATLAB
Distributed Computing Engine. For a lis t of products that are
not eligible f or use with Distributed Computing Toolbox, see
http://www.mathworks.com/product s/ineligible_progra ms/.
fine-grained application
An application for which run time is significantly less than the
communication time needed to start and stop the program. Com pare to
coarse-grain ed app lications.
head node
Usually, the node of the cluster d esignated for running the job manager
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 homog eneo us.
homogeneous cluster
A cluster of identical machines, in terms of both hardware a nd software.
