When using the Parallel Computing Toolbox with the local scheduler it can only be used on that single machine.
If interested in utilizing workers on multiple computers, we offer MATLAB Parallel Server, which can be used across multiple machines. More information on MATLAB Parallel Server can be found here:
This is a bug in the "train" function of the Neural Network toolbox in the way the time information of the timedelaynet is analyzed prior to sending to the workers, making it appear internally as though the network training cannot be parallelized.
This behavior is a side-effect of the following bug:
