Toolbox and Engine Components
If you have a large cluster, you probably already have a sche duler. Consult
your MathWorks repres entative if you have questions about cluster size
and the job manager.
Who administers your cluster?
The person administering your cluster might have a preference for how
jobs are scheduled.
Components on Mixed Platforms or Heterogeneous
Clusters
Distributed Computing Toolbox and MATLAB Distributed Computing Engine
are supported on Windows, UNIX, and Macintosh platforms. Mixed platforms
are supported, so that the clients, job managers, and workers do not have to
beonthesameplatform.Theclustercanalsobecomprisedofboth32-bitand
64-bit machines, so long as your data does not exceed the limitations posed
by the 32-bit systems.
For a complete listing of all network requirements, including those for
heterogeneous environments, see the System Requirements page for the
MATLAB Distributed Computing Engine at
http://www.mathworks.com/products/distriben/requi reme nts.html
In a mix ed platform environment, be sure to follow the proper installation
instructions for each local machine on which you are installing the software.
MATLAB Distributed Computing Engine Service
If you are using the M athWorks job manager, every machine that hosts a
worker or job mana ge r sess io n m u st also ru n the MATLAB Di stributed
Computing Engine (m dce) service.
The mdce service recovers worker and job manager sessions when their
host machines crash. If a worker or job manager machine crashes, w hen
mdce starts up again (usually configured to start at machine boot time), it
automatically restarts the job manager and w orker sessions to resume their
sessions from before the s ystem crash.
