I have a workflow that uses the MATLAB project functions to retrieve information from the MATLAB project. I use currentProject() to get the matlab.project.Project object.
I am trying to run this workflow using the Parallel Computing Toolbox, but seems that the MATLAB project is not available in the MATLAB workers.
Tested it using this code:
parpool(2);
spmd
currentProject();
end
Does the MATLAB project gets transferred into the MATLAB workers, or only the MATLAB path?
Any workaround about how can I pull the Project Reference information in a distributed environment?
Thanks in advance!

You can open the project on all workers before the loop with parfevalOnAll.
gcp
rf = currentProject().RootFolder
parfevalOnAll(@()openProject(rf), 0)
parfor ii = 1:4
disp(currentProject().RootFolder)
end

I was having a similar issue with a test suite (and runInParallel) That solution works thank you @Sean de Wolski
In the future will this be changed so that the open projects are instantiated on the workers without user input? Or is this the intended behavior?
