poolStartup

poolStartup runs automatically on a worker each time the worker forms part of a parallel pool. You do not call this function from the client session, nor explicitly as part of a task function.

To define the pool initialization on the worker, add MATLAB^® code to the poolStartup.m file. The worker looks for poolStartup.m in this order, executing the first one it finds:

To create a version of poolStartup.m for the AttachedFiles or AdditionalPaths properties, copy the provided file and modify it as required.

matlabroot/toolbox/parallel/user/poolStartup.m

Use the poolStartup function to run startup code required for parallel execution on the parallel pool. For example, you might want to include code for using mpiSettings. Because jobStartup and taskStartup execute before poolStartup, they are not suited to pool-specific code. Use taskStartup for setup code on your worker regardless of whether the task is from an independent job, communicating job, or using a parallel pool. Use poolStartup to setup code for pool usage only.

For further details on poolStartup and its implementation, see the text in the installed poolStartup.m file.
