Parallel Preferences

6-13

• Automatically create a parallel pool — This setting causes a pool to automatically

start if one is not already running at the time a parallel language is encountered that

runs on a pool, such as:

• parfor

• spmd

• distributed

• Composite

• parfeval

• parfevalOnAll

• gcp

• mapreduce

• mapreducer

With this setting, you never need to manually open a pool using the parpool

function. If a pool automatically opens, you can still access the pool object with gcp.

• Shut down and delete a parallel pool — The pool’s IdleTimeout property setting

causes a parallel pool to automatically shut down if the pool has been idle for the

specified amount of time. Whenever the pool is used (for example, with a parfor

or parfeval), the timeout counter is reset. When the timeout is about to expire, a

tooltip on the desktop pool indicator warns you and allows you to reset the timer.
