Icon color and tool tips let you know if the pool is busy or ready, how large it is, and
when it might time out. You can click the icon to start a pool, stop a pool, or access your
parallel preferences.
New Parallel Preferences
Your MATLAB preferences now include a group of settings for parallel preferences.
These settings control general behavior of clusters and parallel pools for your MATLAB
session.
You can access your parallel preferences in these ways:
• In the Environment section of the Home tab, click Parallel > Parallel
Preferences
• Click the desktop pool indicator icon, and select Parallel preferences.
• Type preferences at the command line, and click the Parallel Computing Toolbox
node.
Settings in your parallel preferences control the default cluster choice, and the preferred
size, automatic opening, and timeout conditions for parallel pools. For more information
about these settings, see Parallel Preferences.
Automatic start of a parallel pool when executing code that uses parfor
or spmd
You can set your parallel preferences so that a parallel pool automatically starts
whenever you execute a language construct that runs on a pool, such as parfor, spmd,
Composite, distributed, parfeval, and parfevalOnAll.
