Parallel Computing: Execute GUI and programm parallel

7 次查看(过去 30 天)
Hello, I would like to start a GUI (GUIDE) and parallel execute another job. Is there any solution how to realise that problem. When I start the GUI for example in a parfor no User-Interface pops up.

It is not possible to do graphics from inside a worker.
There is a demonstration around, written by one of the Mathworks people, that deals with collecting results from multiple workers as they come in, and graphing the results. Unfortunately I do not seem to find that at the moment. It might have used parfeval.
The point is that with some care you can transfer data back to a controlling routine that plots data that has been generated by the workers; however, it does not allow multiple workers to draw graphics.

That means calling parfevalOnAll before calling the actual function?
I tried the following.
T = parfevalOnAll(@loadNetAssembly,0);
try
import ASAM.HILAPI.dSPACE.MAPort.*;
import ASAM.HILAPI.Implementation.Common.ValueContainer.*;
catch e
error(e.message)
end
F = parfeval(@batchTest,0, myview);
And the function loadNetAssembly looks the following.
function loadNetAssembly()
NET.addAssembly('dSPACE.HILAPI.MAPort');
NET.addAssembly('dSPACE.HILAPI.Common');
NET.addAssembly('ASAM.HILAPI.Implementation');
NET.addAssembly('ASAM.HILAPI.Interfaces');
import ASAM.HILAPI.dSPACE.MAPort.*;
import ASAM.HILAPI.Implementation.Common.ValueContainer.*;
I still get the same error. Sorry if I didn't unserstand it right.

I am not familiar with how NET and import works, sorry. Perhaps you need to attach files to the pool ? https://www.mathworks.com/help/distcomp/addattachedfiles.html
