Renamed Functions for Product Name Changes
As of result of the product name changes, some function names are changing in this

• dctconfig has been renamed pctconfig.
• dctRunOnAll has been renamed pctRunOnAll.
New batch Function
The new batch function allows you to offload work from the client to one or more
workers. The batch submission can run scripts that can include jobs that distribute
work to other workers. For more information, see the batch reference page, and Getting
Started in the Parallel Computing Toolbox User's Guide.
New Matlabpool Job
The batch functionality is implemented using the new MATLABpool job feature. A
MATLAB pool job uses one worker to distribute a job to other workers, thereby freeing
the client from the burden of tracking and job's progress and manipulating data. For
more information, see the createMatlabPoolJob reference page.
Enhanced Job Creation Functions
The createJob and createParallelJob functions have been enhanced to run
without requiring a scheduler object as an argument. This is also true for the new
createMatlabPoolJob function. When a scheduler is not specified, the function uses the
scheduler identified in the applicable parallel configuration. For details, see the reference
page for each function.
Increased Data Size Transfers
The default size limitation on data transfers between clients and workers has been
significantly increased. In previous releases the default limitation imposed by the JVM
