Is it possible to use pctRunOnAll as a batch?

Hi,

I have a script that will only allow me to parallel it if i use pctRunOnAll because it uses a simulation plugin that only likes one instantiation and does not like parfor. As a pctRunONAll, it works fine.

I want to get this parallel work to operate in a batch in the background. Is it possible to combine pctRunOnAll with a batch?

Am i able to do this?

 j = batch(pctRunOnAll 'script1', 'matlabpool', 10, 'CaptureDiary', true);

Thanks Bobby

While you can use pctRunOnAll with batch, it's a little awkward. Here's what you need to do:

j = batch(@pctRunOnAll, 0, {'script1'}, 'Pool', 10, 'CaptureDiary', true)

Here we're using the form of batch which takes a function handle - in this case @pctRunOnAll. Then, we must specify the number of output arguments from that function - which is 0, and then the input arguments as a cell array, {'script1'}.

One other option you might wish to explore is wrapping up your task inside a function, and then you can use parfeval to run multiple iterations. This is also compatible with batch.
